Chili; Bridges, (n. 511). Cuming, (n. 90.) Buenos Ayres; Tweedie.—We scarcely think Humboldt's plant can be distinct from ours. Cathartic powers are stated by Humboldt to be attributed to it. Tweedie remarks that it has the property of rendering meat that has been almost putrid, sweet.

1123. (3.) X. ambrosioides (Hook. et Arn.); spinosum tomentoso-incanum, caule procumbente, foliis bipinnatifidis, segmentis oblongis obtusis margine revolutis, capituli fœminei solitarii aculeis tenuibus setiformibus patentibus apice uncinatis, spina terminali valida recta.—β. capituli fœm. spina valida nulla.—Los Caldanes, Province of Cordova; Dr Gillies. Buenos Ayres; Tweedie.—This very distinct species has the finely cut foliage of Ambrosia, and the fruit of Xanthium. The terminal spine of the female capitulum is frequently wanting.

Prodr. v. p. 549.—Mendoza and La Aguadita, province of San Luis; Dr Gillies. Buenos Ayres and Monte Video; Tweedie, (n. 372.)—Pappi paleæ paucæ, breves, 1—2 longiores ut in Heliantho, sect. Harpalio, at omnes in pappum coroniformem coalitæ, haud, ut in Heliantho, liberæ.—All authors indicate Chili as the native country of this plant; probably Mendoza is meant in those cases; for we have not seen any specimens from the Chilian side of the Andes.


Capitulum homogamum. Involucrum subbiseriale. Receptaculum paleaceum. Paleæ lineares. Antheræ nigricantes, exsertæ, ecaudatæ alis cordato-oblongis. Stylus Tagetis (i. e. alte bifidus, ramis sursum latioribus, cono acuto superatis, pube e coni basi sursum adscendente deorsumque descendente.) Achænium compressum, obcordatum, omnino calvum, conforme, glabrum, disco epigyno inconspicuo.—Frutex ex insulis Gallipagensibus. Folia lineari-lanceolata, utrinque attenuata, alterna, supra scabriuscula, subtus pubescentia, integerrima. Capitula basi subintrusa, axillaria, breviter pedunculata.

Prod. vii. p. 308.—Hook. ic. ined.—Gallipagos; Cuming, (n. 106.).—A very distinct genus unlike any with which we are acquainted. Leaves 4—6 inches long, much attenuated at both extremities, subsessile, penninerved, scabrous above, downy and paler beneath. Capitula nearly an inch broad. Involucre campanulate, slightly downy. Corollas all tubular, pale, apparently white. Anther-tube exserted, black, tipped with white. Paleæ nearly as long as the florets, linear, rigid.

Helianthus rivularis, Poep. Pl. Exsicc. n. 716.—Tetrachæte Chilensis, (H. et A.) mst.—Banks of the River Valdivia, Chili ; Bridges, (n. 764.)—The leaves are slightly scabrous on the upper side; the ovaries in our specimens are young, but appear to have a pappus of four equal bristles, so very caducous, that we have seldom been able to detect the whole number although the marks where the others have existed are visible. De Candolle describes the mature achenium with only two bristles. The branches of the style of the disk are tipped with a very short fleshy cone, on which account we have placed the genus with the Senecionideæ whicle De Candolle places it in Asteroidæ, near Siegesbeckia.


* Foliis alternis.

1135. (1.) Leighia anchusæfolia (DC. Prodr. v. p. 580); herbacea strigoso-pubeseens, foliis alternis sessilibus calloso-strigosis lineari-oblongis subintegerrimis triplinervibus, nervis lateralibus prope margines, pedunculis corymbosis elongatis perve-foliatis, involucri 3—4-serialis strigosi disco brevieris foliolis oblongo-lanceolatis ext. minoribus apice recurvis, achenio parce sericeo.—Top of the hill of Monte Video; Tweedie, (n. 865.)

Prodr. p. 581., but the stem is scabrous, and the marginal nerves of the leaves can leaves can be traced.

1137. (3.) L. Gilliesii (H. & A.); suffruticosa? scabra, foliis alternis brevi-petiolatis anguste lanceolatis attenuatis basi in petiolum acuminatis integerrimis trinerviis, nervis lateralibus prope marginem, pedunculo solitario valde elon-

Perhaps L. calendulacea, DC., may be a state of this very common plant of South Brazil and the Platte river.

1140. (6.) L. Silphoides (H. & A.); herbacea? hispida, foliis petiolatis oppositis in petiolum decurrentibus, caulinis sagittato-ovatis inciso-dentatis angulatisque, superioribus hastato-oblongis serratis, omnibus supra venisque subtus calloso-hispidis subtus inter venas velutinis vel dense pubescen-

1149. (3.)

Prodr, p. 614?—Buenos Ayres; Tweedie.

[page] 316

1150. (.4.) V. helianthoides (H. & A.); herbacea? foliis (ramorum) opposites hirsutis inferioribus oblongis superioribus lineari-lanceolatis dentatis, pedunculis solitariis versus apicem villosis involucri laxi foliolis exterioribus villosis spathulatis acutis basi attenuatis internis glabriusculis acuminatis, radio discum superante, acheniis radii triaristatis disci biaristatis.—Dry pasture-fields in the interior of Entro Rios; Tweedie.

1151. (1 .) Oligogyne? Synedrelloides, (H. & A.); herbacea parce strigilloso-pubescens, foliis oppositis petiolatis ovatis acutis serratis, pedunculis petiolum raro superantibus in dichotomia solitariis ad ramorum apices ternis, involucro subbise- riali, foliolis exterioribus majoribus elliptico-oblongis acutis, radio brevi, acheniis obcompressis radii brevissime disci longiuscule biaristatis.—Rio Grande; Tweedie.—This may possibly be the O. Megapotamica, DC. Prodr.5 p. 629; but the involucre is not decidedly in a single row as he characterizes the genus. It has quite the habit of Synedrella nodiflora.

1152. (1.) Ximenia microptera, DC. p. 627.—X. enceloides, Don, in litt. (non Pav.)—Cerro del Diamante, Mendoza; Dr Gillies. Buenos Ayres; Tweedie.—Herba annua, cenescens. Folia opposita et alterna, sublonge petiolate, integra, sublangulato-ovata, inæqualiter serrata, sabtus incanostrigillosa, basi in petiolum subdecurrentia. Petioli basi ex-auriculati. Pedunculi 1—3-ni, terminales.—This differs from X. enceloides, Cav., at first sight, by the petioles not expanding into foliaceous acuricles at the base. The bristles at the apex of the ovary are very small, inconspicuous, and easily broken off, but we fear that character is not constant. In-deed Cavanilles himself has represented the original species in the same way, although in the cultivated specimens of it, in our Herbarium, we find always very decided awns. Kunth describes ray as neuter in the new species he refers to this genus: Cavanilles makes it female, as does Lessing, who, however, suspects the achenium to be unfertile; but we possess specimens having the achenia of the ray perfect. It is ovoid, much warted and wrinkled, without any a wing. It

[page] 317

is therefore probable that the species wait a neuter ray ought to be referred to Coreopsis, or that Simsia ought again, as Cassine and De Candolle suggest, to be restored for them.

1153. (1.) Spilanthes (Salivaria) Macræi (H. & A.); stolonifera, foliis lineari-spathulatis obtusinsculis sessilibus utrinque glabris vel pilis brevibus raris adspersis versus basin ciliatis, pedunculo foliis vix duplo longiore pilis brevibus plus minusve adsperso, involueri foliolis ovalibus interioribus apice erosis, radio nullo, disco hemispherico.—S. leiocarpa, DC. Prodr. 5. p. 626?—Conception, Chili; Macrae.—S. leiocarpa, DC. agrees tolerably well with this, and it is also a plant of Macrae; but, as stated by De Candolle. discovered "ad Sinum Chorillo in Peru," whereas ours is from Chili.

1154. (2) S.(Salivaria) pusilla,(H. & A.); repens, foliis spathulato-linearibus obtusiusculis basi in petiolum attenuatis glaberrimis, pedunculo foliis duplo longiore versus apicem subpubescente, involucri foliolis late ovalibus margine scariosis minute fimbriatis, radio nullo.—Road-sides about Bue-nos Ayres; Dr Gillies. Banda Orientale; Tweedie.

1155.(3.) S. (Acmella) helenioides, (H. & A.); erecta glabra, foliis oblongis lineari-lanceolatis linearibusve calloso-apiculatis basi attenuatis integerrimis vel utrinque sub-dentatis, pedunculis valde elongatis, radii flosculis patenti-recurvis apice tiifidis disco subcylindrico longioribas.— Mendoza and Buenos Ayres; Dr Gillies. Uraguay and Rio Grande; Tweedie, (n. 864, 858, and 867.)

1156. (4.) S. (Acmella) affinis, (H. & A.); decumbens, caule glabro, foliis linearibus utrinque attenuatis calloso- apiculatis hinc inde calloso-denticulatis, pedunculis elongatis versus apicem dense pubescentibus, flosculis radii disum, conicum subæquantibus obtuse tridentatis.—Los Loamos in, Patagonia; Tweedie (in Herb. Arn.)—Very nearly allied to S. stenophylla, and to S. helenioides, but the florets of the ray are only toothed, not trifid.

1157. (5.) S. (Acmella) stenophylla, (H. & A.); decumbens glabra, foliis angustissime linearibus calloso-apiculatis bine

S. wedelioides, (H. & A.); decumbens, caule pedunculis petiolisque strigoso-pubescentibus, foliis obovatooblongis trinerviis basi in petiolum breviusculum paullum attenuatis glabris margine scabridis integerrimis, pedunculo gracili, capitulo basi subtruncato, flosculis radii (pallidis) oblongis involucrum hand superante, rachidis bracteolis subulatis corollas disci superantibus, ovarii marginibus inferne glabriusculis apice villosiusculis, setis perbrevibus mucroni- formibus!, styli ramis subtruncatis pube descendente obsessis!—Within the tide of La Plata. Tweedie, (in Herb. Arn.)—The style has no appendage or cone; but its pubescence is not manifestly longer than the apex, as in the true species, of the genus. The external appearance of the style is thus more of the Asteroideæ than of the Senecionidæ; but the stigmatic lines reach to about the apex, and therefore much beyond the commencement of the pubescence.


Adenocarpus. Don, mst. (non DC.)

GEN. CHAR. Capintulum heterogamum. Involucrum duplici ordine 10-phyllum, æquale, foliolis oblongis obtusis margine membranaceis. Styli rami radii lævissimi breves exappendiculati, disci appendiculis linearibus longissismis superati. Achenium verrucosum erostre, radii cylindricum exalatum calvum disci obcompressum bialatum, alis apice in mucrones tuberculiformes brevissimos ac lævissimos excurrentibus. Rachis bracteolata.

1159. (1.) A. tuberculatum, (H. & A.)—Adenocaripum tuberculatom, Don, mst.—Province of Cordova; Dr Gillies. Cordova; Tweedie, (n. 1109).—A small, procumbent, berbaceous plant, with the habit of Heterospermum pinnatum. Leaves altertnate,on long petioles, tripinnatifid, strongly nerved and reticulated, pellucid in the areolæ; segments linear-lan-

ceolate very acute or mucronate. Capitula small, hemispherical, on axillary and terminal peduncles. The genus is very closely allied in character to Isostigma of Lessing, and indeed only to be distinguished by the achenia and styles: but in habit the two genera are totally dissimilar.

sifolia ; β. Bridgesii, DC. Prodr. v. p.665.—Valparaiso and Quepay; Bridges, (n. 449.); Cuming, (n. 724.)—Our plant is certainly the Hymenatherum Kunthii of Lessing, and we prefer his specific name as he is the first describer of it. It is certainly the Rancagua Bridgesii Endlicher and Poeppig, although our plant is not glabrous, and the paleæ of the pappus are narrow linear-subulate, and very obscurely and simply serrated, The R. Feuillei, Endl. and Poepp., (Lasthenia obtusifolia, α of DC.) has a different structure of the paleæ of the pappus, which are much shorter than the corolla, though the two plants are in other respects very similar.

1167. (1.) Hymenatherum Candolleanum (H. & A.); perennis pubescens, ramis simpliciusculis, foliis oppositis sessilibus ad basin subpalmatis pinnato-partitis lobis sub 5 spinoso-filiformibus rigidis integerrimis inferioribus minoribus terminali elongato, pedunculis elongatis 1-cephalis nudis, involucro biseriali 14—20-dentato, pappi uniserialis squmellis 10 omnibus basi membranaceis apice trifidis, lobo medio setiformi scabro, lateralibus brevibus membranaceis.—H.

Patagonia ; Tweedie.—We almost incline to think that this may be the same as Cassini's H. tenuifolium, (from "Chili,") and the same as what De Candolle had from Née, (probably from Mendoza,) both of which De Candolle is inclined to refer to his H. tenuilobum, a Mexican plant. Lessing's genus Hymenaherum, it will be observed, is very different from this of Cassini, and is Cassini's Losithenia.

Subtrib. V. HELENIEÆ. Less.

1168. (1.) Bahia ambrosioides, Less.—DC. Prodr, v. p. 657.—Valparaiso, Cuming, (n. 769.) Bridges, (n. 60.) Mathews, (n. 168.)— Fruticulus dense pubescens. Folia opposita biternatim secta; segmmentis cuneoto-oblongis, acutis. Capitula coymbosa, heterogama, radio 5—9-flavo. Involucrum sub-

biseriale, sub-9-phyllum foliolis cuneato-rotundatis. Styli disci rami cono brevi carnoso glabriusculo apiculato superati. Achenium tetragonum, basi longe attenuatum, glabriusculum. Pappi paleæ 8—10, cuneato-obovatæ, æquilongæ latitudine, inæquales, apice obtusæ, vel truncatæet eroso-dentatæ, corneo-membranaceæ.—Perhaps the genus Bahia ought to be restricted to this plant. B. artemisiæfolia, and probably all the other species from California and Mexico have truncated styles, as Lessing indeed defines Bahia, and belong to Eriophyllum, Lag., from which Trichophyllum, Nutt., is not distinct. Erioph. trolliifolium, having a pappus of 4 acute paleæ, seems to belong to Hymenoxys.


Capitulum homogamum. Receptaculum epaleaceum. Involucri squamæ 5,uniseriales, cuneato-obovatæ, obtusissimæ. Corolla brevis, 5-dentata. Styli rami cono brevi hirsuto superati. Achenia breviter turbinata, tetragona, glabriuscula. Pappi paleæ 8—10, cuneato-obovatæ æquilongæ, latitudine paullo inæquales, obtusæ, muticæ, corolla paullo breviores, corneo-membranaceæ, pinnatifido-striatæ, eroso-denticulatæ. —Herba annua pusilla glabra pice corymbose ramosa. Folia inferiora opposita, superiora alterna, subpedatim secta, segmentis angustissime linearibus obtusis. Capitula solitaria breviter pedunculato.

1169. (1.) A. pusillus, (H. et A.)—Coquimbo, Cuming,(n. 885.)—This genus differs from Achyropappus, in the form of the style, the want of a ray, and habit; from Florestina by the absence of the subulate hairy appendages to the style; and from Hymenopappus by the involucre, the style, and the achenia. In character it is most allied to the original Bahia, but there is no ray, and the habit is totally dissimilar.

Buenos Ayres; Tweedie.—In this and the next species, the branches of the style are tipped with a short cone, and the achenia are remarkably hirsute at the very base, and sprinkled upwards with a few stiff hairs.

1171. (2.) S. multiflora, (H. et A.); strigoso-pubescens, foliis inferioribus oppositis superioribus alternis subtripinnatisecits, segmentis anguste linearibus obtusis, capitulis sublonge pedunculatis multifloris homogamis? involucro subtriseriali 12—18-phyllo foliolis subæqualibus, corollis 5-dentatis, achenio basi hirsuto, pappi paleis 8 subæqualibus scariosis basi crassinerviis, 4 obtusis v. acutiusculis, 4 setigeris. —Achyropappus schkuhrioides, Don, (non Link.)—Mendoza; Dr Gillies.—We do not find any ligulate floret in this species; but the ligules may have fallen off, as our specimens are considerably advanced.

1172. (1.) Jaumea linearifolia, Pers.—DC. Prodr.v.p. 663. —Kleinia linearifolia, Juss. in Ann. Mus. ii. p. 424. tab. 61. f. 1. (non Linn.)—In salt marshes of St Lucia and Monte Video, also at Bahia Blanca, N. Patagonia; Tweedie.—De Candolle, who does not appear to have seen the plant, describes the pappus of 8—10 squamellæ but Jussieu correctly figures and describes the squamellæ as numerous.

1173. (1.) Cercostylis scabiosoides, (Arn.); foliis oblongolanceolatis acutis vel semel bisve pinnatifidis,—Arn. in DC. Prodr. vii. p. 293.—Cephalophora scabiosioides, Don, mst.

1174. (1.) Hymenoxys anthemoides, (Cass.?); herbacea glabra humilis divaricato-ramosa, foliis biternatim sectis vel superioribus alte trifidis segmentis filiformibus, involucro fructus connivente, squamis ovalibus obtusis serie interiore exteriorem superante, capitulis discoideis, pappi paleis ovalibus subiter acuminatis.—DC. Prodr. v. p.661.—Buenos Ayres; Tweedie.—We have little doubt of this being Cassini's

[page] 323

plant, and the Hymenopappus anthemoides of Juss., although the remarkable tendency of the involucre to become connivent by age, has not been observed by any of these botanists. If it be really a distinct species, it may be named H. connivens. The branches and peduncles are deeply striated as in H. Hænkeana, from which it is distinguished by its more compound leaves.

1175. (2.) H. Tweedei, (H. et A.): herbacea glabra sub elongata decumbens, foliis anguste linearibus obtusis vel ad medium 2—3-fidis, capitulis radiatis, involucro campanulato squamisoblongo-ovalibus obtusis serie interiore subæquilongo, pappi paleis 5—6 oblongis sensim acuminatis.—Rio Grande, and dry pastures, road sides of Los Loamos, N. Patagonia; Tweedie, (n. 859.)—In this and the last species the inner leaflets of the involucre are coriaceous and flat, the outer ones slightly carinate at the base.

1176. (1.) Cephalophora glauca, Cav.—DC. Prodr. v. p. 662.—Valparaiso and Conception; Cuming, (n. 126, and 553.) Bridges, (n. 220.) Valdivia; Bridges, (n. 651.)—Casa Blanca, Chili; Dr Gillies.

1177. (2.) C. aromatica, DC. Prodr. v. p. 662.—Græmia aromatica, Hook.—Valparaiso; Bridges, (n. 219.) Buenos Ayres (cultivated;) Tweedie.—Although in deference to De Candolle, we retain these two species as distinct, we believe they are mere varieties, and that his C. plantaginea is another form. The difference pointed out in the shape of the leaves is certainly not permanent, and the only one we know lies in the annual or biennial duration of the root, and the size of the capitula; but this last is likewise variable. Both vary from glabrous to canescent; the lower leaves are toothed, the upper entire; those at the base of the ramifications, particularly in our specimens from Tweedie, are slightly decurrent.

1178. (3.) C. heterophylla, (Less.—DC. Prodr. v. p. 662); suffruticosa ramosa canescens, foliis linearibus vel dentatopinnatifidis, involacri squamis adpressis, corollis radii 3-lobatis pallidis, disco purpurascente, pappi paleis circiter 10 elongatis, achenio argenteo-sericeo.—Buenos Ayres; Tweedie,

[page] 324

(n. 889.)—De Candolle has inadvertently made it a part of the generic character that the leaves of the involucre are always reflexed; whereas the greater part of his section Actinella, to which this and the next species belong, has them adpressed.

1179. (4.) C. Doniana, (H. et A.); canescens suffruticosa, foliis linearibus integris acutiusculis, involucri squamis adpressis, corollis radii trilobatis discoque concoloribus, pappi paleis 6—8 breviusculis, achenio fulvo-sericeo.—C. suffruticosa, Don, mst.—C. elongata, Don, mst. (ex parte.)—San Isidro, Mendoza, and Saladillo, province of Cordova; Dr Gillies, (n. 64, and 62, partly.)—Our specimens from Dr Gillies of what he informed us Mr Don has called C. elongata, belong partly to this species, and partly to Cercostylis scabiosoides. Several other species are suffrutescent, whence we have rejected the unpublished name given by Mr Don.

1180. (1.) Calea pinnatifida, Br.—Less. in Linn. v. p. 158, (cum synon.); DC. Prodr. v. p. 674.—St Catharines; Tweedie,(n. 1022.)—Some of our specimens from St Catharines, have the upper leaves quite entire, and agree with the description of C. glabra, DC., found there by Gaudichaud; but our plant has the leaves always more or less scabrous on the upper side.

1181. (2.) C. cymosa, Less. l. c. DC. Prodr. v. p. 674.—S. Brazil; Tweedie, (n. 1066, 1069.)—Our specimens accord with De Candolle's specific character, except that the upper leaves are occasionally slightly obtuse, and that the scales of the involucre are either obtuse or acute in the same corymb: the leaves are scabrous on both sides.

Prodr. v. 673.—C. uniflora, forma discoidea, (Less. l. c. p. 158.)—Banda Orientale; Tweedie, along with the last species.— Lessing is probably correct, when he unites these two species; the only difference lies in the presence or absence of a ray. The following description applies to both.—Folia sessilia, ovata vel ovato-

lanceolata, grosse dentata, utrinque scabra vel hirsuta, triplinervia: involucri foliola vittis longitudinalibus 5—7 purpureis oleo farctis lineolata: pappi paleæ utrinque attenuatæ, sæpissime secus strias pinnatifido-laceræ; receptaculi bracteolæ subsetaceæ, corneæ.

San Isidro, Andes of Mendoza, and frequent in the Quebradas above Mendoza, "where it is in common used as a medicine instead of wormwood;" Dr Gillies.—We cannot see that the A. Absinthium, and the plant is probably an introduced one in the above stations. There is a South Brazilian species called A. Montevidense by Sprengel, very imperfectly described, and we doubt if any Artemisia has been found in a perfectly wild state in the southern hemisphere.

Cape Tres Montes; C. Darwin, Esq.—β. major; minus villosa, foliis glabriusculis segmentis magis discretis, capitulis majoribus.—Fields at chumpulla, near Valdivia; Bridges, (n. 756.)—In our specimens from Mr Bridges, there are no traces of ligulate or marginal female florets, but those of the disk are male in as far as the styles are simple, as in Blennospermum. Ovaries of the male flowers, obovate, compressed, glabrous, and apparently bialate.

1192. (1.) Soliva sessilis, R. P.—DC. Prodr. vi. p. 143.—Valparaiso; Cuming, (n. 475.); Bridges, (n. 539.) Buenos Ayres; Dr Gillies, Tweedie. —The wing of the achenium has, as it were, a peice cut out on each side near the base; and we are of opinion, that the Soliva pterosperma, Less., and DC., (Gymnostylis, Juss.) and the Gymnostylis Chilensis and alata of Sprengel, all belong to this species.

1193. (2.) S. araulis (H. & A.); Acaulis, foliis longe petiolatis pilosiusculis bipinnatisectis, segmentis anguste oblongolinearibus, acutis, capitulis sessilibus radicalibus congestis, acheniis anguste oblongis alis crassiuseulis transversim rugulosis apice villosis in cornua brevissima patentia excurrentibus. —Buenos Ayres; Tweedie. This seems to be very closely allied to S. Lusitanica, Less. (Hippia stolonifera, Brot.) Is it not possible that this, the only species accounted European, may have been introduced by the Portuguese from Buenos Ayres? We have not seen any plant agreeing with S. nasturtiifolia, (Juss.) said to be from Buenos Ayres.

Cuming, (n. 63.)—The root is woody, fusiform, branching above. Stems ten inches to a foot long; capitula crowded, dirty yellow, or cream-coloured; not glossy, but rather opaque; each about four inches long, broad above, and tapering into the short pedicel.

(n. 332.)—We adopt the name of Kunze, which, according to De Candolle, was given in Poeppig's collection of dried specimens the year before our description appeared in the Botany of Beechey's Voyage. We believe that a very limited number of that dried collection was on sale, if they were on sale at all; and we have long endeavoured to obtain access to a set, but in vain. De Candolle gives G. Piravira of Lessing as the same as this, and he places it, though we think incorrectly, in his § AXANTHINA.

Darwin, Esq., (n. 333.)—A very variable species assuredly: we possess specimens from six inches to a foot and a half full, and leaves from one to six inches long. We fear that Gn. Americanum is not distinct from this , and we believe it will be found very general on the North and South American continents. We have specimens from Peru, Columbia and Mexico, West Indies, &c., and they have a striking similarity with the G. sylvaticum and its varieties of Europe.

Mas Afuera; Cuming, (n. 1353.) Andes of Mendoza; Dr Gillies. Maldonado; Dr Gillies. Buenos Ayres; Tweedie. Port George, Patagonia; King's Voyage.—This again is sometimes difficult to be distinguished from the preceding. The glomerules of capitula are less compactly spiked; but it seems to pass into G. spicatum, and it is hardly possible accurately to define any of the species of De Candolle's group, "Capitulis in spicam racemosam dispo-

sitis." Probably some of our varieties of that and the preceding species may be found to answer to the G. stachydifolium, Lam. and DC., and G. Chamissonis, DC.; the first a native of Monte Video; the second of Chili.

2001. (5.) G. alienum, (H. et A.); ramis sterilibus densis brevibus cæspitosis floralibus elongatis gracilibus simplicibus foliisque albo-lanatis, foliis lineari-spathulatis superioribus linearibus, capitulis in spicas terminales interruptas dispositis basi densissime lanosis, involucri cylindracei basi attenuati pulcherrime rosei squamis oblongis acutis erectis imbricatis. —Chili. Cuming, (n. 64.)—This has altogether a very peculiar aspect, something like that of our European Xeranthemum, and quite unlike that of any American Gnaphalium. Perhaps it should form a second species of Helichrysum of that country. The female florets are in several series in the circumference; the hermaphrodite, about six, in the centre; the receptacle is small, naked? The root is small, woody, fusiform; from its top spring many dense, short, leafy branches, 1—2 inches long, and from among them, 4—6 flowering branches, 5—6 inches high, slender, and like the whole plant, except the involucre, clothed with short, white, compact wool; at the base of the involucre the wool is loose and very copious, forming a dense white tomentose cup from which the glossy deep rose-coloured scales of the involucre arise.

Patagonia; Tweedie.—δ. macrantha; ramis elongatis erectis, foliis longioribus siccitate nigrescentibus omnibus indivisis, cpitulis majoribus.—Bahia Blanca, coast of Patagonia; C. Darwin, Esq., (n. 351.)—A very variable plant assuredly; and we think we are correct in bringing the above several varieties under this species. Leaves 2—3 inches long, tipped with a soft mucro, fleshy and as it were compressed, when recent.

[page] 331

2008. (2.) S. vaginatus, (H. et A.); caule erecto fruticoso? glabro subsimplici, foliis carnosis lineari-subulatis acutis erecto-patentibus glabris supra canaliculatis subtus teretibus basi dilatato-vaginatis in axillis (supremis præcipue) lanatis, capitulis paucis subcorymbosis, involucri lato-campanulati subpubescentis foliolis acutis non sphacelatis basi bracteolis paucis parvis subulatis, ligulis 14—15 oblongo-linearibus discum multiflorum subæquantibus.—Berkeley Sound, Falkland Island; C. Darwin, Esq., (n. 362. and 376.)—A very singular species. The leaves are one and a half to two inches long, rigid, and almost black in the dry state. Involucre short in porportion to its breadth. Flowers rather large.

2009. (3.) S. farinifer, (H. et A.); fruticosus pubescentitomentosus, ramis elongatis erectis gracilibus subangulatis, superne subaphyllis, foliis lineari-subulatis mucronatis planis integerrimis uninerviis, capitulis solitariis v. corymbosis; involucri campanulati farinoso-glanduliferi foliolis acuminatis non sphacelatis basi pauci-bracteolatis, ligulis 10—12 latolinearibus discum æquantibus.—Near Vina de la Mar, Chili; Bridges, (n. 223). Valparaiso; Cuming, (n. 583.)—This is a very peculiar plant, of which we find no description among the numerous Chilian species of Senecio, described by De Candolle. The branches are from six inches to a foot long. The flowers moderately large; in the older specimens more than an inch across.

2010. (4.) S. Chilensis, Less.—DC. Prodr. vi. p. 415.—Cineraria Montevidensis, Spr. (fide Lehm. in Herb. Nostr.)—S. cuspidatus, DC. Prodr. vi. p. 419.—Monte Video; Tweedie.—Maule Province; Cuming, (n. 337.)—We can perceive no difference between the specimens found on the Pacific and the Atlantic side of America.

2011. (5.) S. phagnalodes, DC. Prodr. vi. p. 415.—S. gummifer; H. et A. mst.—Conception; (D'Urville); Cuming, (n. 825.)—This has smaller and much more crowded leaves than S. Chilensis, and the flowering branches are more elongated and almost leafless. There is too in our specimens, a

[page] 332

viscid substance, which causes particles of fine black sand to adhere to the branches and leaves.

2012. (6.) S. ceratophyllus, (Don, mst.); suffruticosus lana arachnoidea decidua vestitus, ramis angulatis superne subaphyllis monocephalis, foliis lineari-spathulatis mucronatis planis apice tridentatis supremis nunc integerrimis, involucri campanulati foliolis subulatis basi pauci-bracteolatis non sphacelatis sub-14 lato-linearibus.—α. major; ramis foliisque elongatis, foliis superioribus integerrimis.—Bahia Blanca, N. Patagonia; Tweedie, (n. 40) C. Darwin, Esq., (n. 368).—β. nana; ramis brevissimis dense foliatis, foliis omnibus tridentatis carnosis. S. Chili; Captain Reynolds.—The capitula are alike in both these varieties; our β may, perhaps, form a distinct species. Our α. is closely allied to S. Chilensis, and may possibly be a state of it with trifid leaves.

2013. (7.) S. Donianus, (H. et A.); suffruticosus? dense albo-lanatus lana demum decidua, foliis remotiusculis subcarnosis lato-lanceolatis basi attenuatis grosse dentato-pinnatifidis, corymbis oligocephalis, involucri campanulati foliolis acuminatis, ligulis.…?—S. lanuginosus, Don, (non Spr).— Summit of the Cumbre, and Paramillo delas Cuevas, Andes of Mendoza; Dr Gillies.—Our specimens of this plant are very imperfect; we are even doubtful if the capitula be not discoid rather than radiate, and if the stems be not herbaceous; but the leaves are very peculiar, and about an inch long.

2014. (8.) S. Eightsii, (H. et A.); humilis fruticosus valde ramosus, ramis brevibus erectis glabris inferne nudis cicatricatis superne dense foliosis, foliis spathulatis apice æqualiter profunde trifidis subtus deciduo-tomentosis marginibus subrevolutis laciniis linearibus obtusis, capitulis solitariis terminalibus sessilibus, involucri campanulati foliolis acutis apice nigro-sphacelatis glabris basi paucibracteolatis tomentosis, ligulis sub-12.—Staten Land, Cape Horn; Dr Eights, n.39.)—A small, well marked species, 4—6 inches high, with copious, alternate, erect branches; very leafy above, bare beneath, and marked with the scars of fallen leaves. Flowers

[page] 333

about three-fourths of an inch across. Scales of the involucre tipped with deep black.—It cannot be the S. trifurcatus, DC. (Cineraria, Spr.), from the Straits of Magellan; for that has an herbacceous and scapiform stem.

2015. (9.) S. Darwinii, (H. et A.); humilis fruticosus dense albo-arachnoideo-lanatus, ramis apice subaphyllo monocephalo, foliis patentibus obovato-spathulatis coriaceis apice trifidis, involucri late campanulati foliolis acuminatis demum glabris basi pauci-bracteolatis, ligulis 12—14 lato-linearibus distincte 3-nerviis disco brevioribus.—South part of Terra del Fuego; C. Darwin, Esq., (n. 359.)—β. laxus; foliis remotis basi sublonge attenuatis.—Same locality; C. Darwin, Esq.

2016. (10.) S. heterotrichus, DC. Prodr. vi. p. 419.—Puerto Bravo, S. Brazil; Tweedie, (n. 1353.)—This is well names and well described by De Candolle. In some specimens the toothing of the leaves is very distinct, and the teeth terminated by a black gland.

** Foliis pinnatifidis, lobis magis minusve profundis.

2017. (11.) S. limbardioides, (H. et A.); fruticosus glaber, ramis elongatis striatis copiose foliatis, foliis lanceolatis basi attenuatis subcoriaceis enerviis pinnato-lobatis lobis brevibus integerrimis acutis, corymbis terminalibus pedunculis pedicellisque gracilibus, involucri campanulati basi calyculati foliolis acutis vix sphacelatis, ligulis lato-oblongis discum multiflorum superantibus nervosis.—Sandy hills about Quintero; Bridges, (n. 393)—β. Foliis angustioribus lobis paucioribus nune integerrimis.—Valparaiso; Cuming, (n. 614.)—This must, we should think, be described in De Candolle, yet we do not find that the charcter of any of his species corresponds with it. The leaves are two inches long, half an inch broad, narrower in β., and less pinnatifid; indeed this latter is as much entitled to rank in the preceding as in the present group.

2018. (12.) S. Berterianus, Colla.—DC. Prodr. vi. p. 417.—Coquimbo; Cuming, (910.)—Habit of the last; but with a

[page] 334

glandular pubescence, longer and narrower leaves, the lobes more numerous, short, but frequently toothed, as well as the rachis, giving a ragged appearance to the margin of the leaves. Our S. bipinnatifidus, Bot. of Beech. Voy. p. 32, is probably not different from this.

2019. (13.) S. alcicornis, (H. & A.); fruticosus glaber, ramis elongatis strictis striatis superne subaphyllis, foliis lanceolatis acuminatis irregulariter laciniato-pinnatifidis laciniis elongatis lineari-acuminatis foliorum supremorum angustissimis, corymbis terminalibus 4-8-cephalis, involucri lato-campanulati foliolis acutis non sphacelatis basi bracteolis tenuibus, ligulis sub-10 latiusculis nervosis disco brevioribus.—Coquimbo; Cuming, (n. 859.)—The very ragged appearance of the leaves, from the irregular manner in which they are divided, is quite peculiar, as far as we know, to this species: the segments are much acuminated. The texture is thin, and there is an indistinct reticulated venation. Yet there is a good deal of similarity of habit in this and the two preceding species.

2020. (14.) S. barbatus, (Don. mst.); humilis fruticosus dichotome ramosus, ramis pedunculis foliis axillisque præcipue laxa densissima laxa demum decidua vestitis, foliis brevibus coriaceo-carnosis acutis bipinnato-lobatis subtus canaliculatis, lobis brevibus acutis rachibusque lato-linearibus, capitulo solitario terminali, involucri campanulati foliolis paucis (sub-10) acutis margine diaphanis basi calyculatis lanatis non sphacelatis, ligulis 10 brevibus ovali-oblongis.—Ascent of El Alto de los Manantiales, Andes of Mendoza; Dr Gillies.—A very singular looking, tortuous, little, shrubby plant; so woolly, especially in the axils of the leaves, that the branches look like those of some of the South American woolly Talina. Leaves short, scarcely half-an-inch long, rigid, pungent. Leaflets of the involucre singularly pale, and diaphanous at the margins.

2021. (15.) S glandulosus, (Don. mst.); fruticosus pubescenti-glandulosus, foliis remotiusculis lineari-lanceolatis acutis pinnato-lobatis marginibus reflexis, lobis paucis brevibus acutis, capitulis terminalibus solitariis vel 2-4 subcorymbosis,

involucri campanulati foliolis acutis glandulosis busi calyculatis, ligulis .…?—Andes of Mendoza; Dr Gillies.—Base of the plant quite woody; the flowering branches, except at the base, herbaceous and pubescenti-glandular. Our specimens are not very perfect; but we know of nothing which will accord with it.

Haheæfolius, to which De Candolle attributes quite entire lobes to the leaves, in our specimens, passes gradually into those states with variously compound leaves; indeed entire leaves,and pinnatifid, and bipinnatifid, may often be seen on one and the same plant: we doubt if the viscid character of the branches (by no means constant,) can be considered a distinctive character or even the glands our var. γ.

Brazil ; Tweedie, (n. 1071, 1072.) This is a splendid plant, from one to three or four feet high, with flowers two inches and more in diameter, the ray purple.

2029. (23.) S. Brunonianus, (H. & A.); annuus albo-pubescenti-tomentosus ramosus, ramis striatis, foliis inferioribus lanceolato-spathulatis integris reliquis lineari-lanceolatis obtusis pinnatifidis lobis brevibus inæqualibus, corymbis foliosis, involucri campanulati glabri bracteolis minutis calyculati foliolis acuminatis sphacelatis, ligulis lato-linearibus sub-12 disco longioribus.—Coquimbo; Cuming, (n. 898.)—This has a small annual tap-root, throwing up three or four stems, which are a span to a foot high, and dichotomously branched every where, as well as the leaves hoary with whitish tomentum, more lax and arachnoid on the branches, and terminated by many yellow flowers, an inch and a half in diameter.

2030. (24.) S. adenotrichius, (DC. Prod. vi. p. 416?); elatus totus hirsuto-vel pubescenti-glandulosus, caule striato, foliis sessilibus pinnatifidis ac inciso-lobatis segmentis acutis, corymbis amplis polycephalis foliosis,capitulis magnis, involucri calyculati late campanulati foliolis acutis exterioribus subulatis laxis interiora subæquantibus, ligulis numerosis angustis vix discum æquantibus.—Chili, near Quillota; Bridges, (n. 391.)

four, or five inches long. Flowers yellow, an inch and a-half in diameter. Our specimens have no great resemblance to the figure of De Candolle's plant, given in the Bot. Reg. t. 1190, under the name of adenotrichia amplexicaulis; but as that represents it in a state of cultivation, they may prove the same.

2032. (26.) S. Cumingii, (H. & A.); elatus, caule hirsutoglanduloso, ramis sparse pubescenti-glandulosis, foliis (amplis) late ovatis obtusis pinnatifidis sinuato-lobatisque, inferioribus petiolatis petiolis lato-alatis basi auriculato-amplexicaulibus, intermediis sessilibus lato-auriculatis, supremis acuminatis dentatis, corymbis terminalibus subaphyllis, pedicellis elongatis superne incrassatis, involucro lato-campanulato non sphacelato hirto-glanduloso, ligulis latis discum subæquantibus. Valparaiso; Cuming, (n. 329.)—Leaves large, two and three inches broad. Flowers large, with broad ligules. Involucre and pedicels very glandular, the latter with several subulate bracteas.

2033. (27.) S.

Our specimen is evidently only an upper branch. This is every-where, as well es the involucre, thickly clothed with viscid, patent, glandular hairs. The flowers are very large, nearly three inches in diameter; the ligules deep yellow.

Radical leaves a span long, and thin petioles still longer. Corymbs large or long, almost naked stalks, which are again divided. Involucre with rather broad acuminated leaflets, nearly black when dry. We do not find any specific difference between the plant of Tweedie from Buenos Ayres, and that from Valdivia.

2041. (35.) S. Bonariensis, (H. & A.); erectus glaberrimus simplex, caule fistuloso parce folioso, foliis oblongo-lanceolatis obtusiusculis subdentatis, radicalibus longe, petiolatis petiolo basi dilatato, caulinis sessilibus basi latis subsagittatis, corymbo denso, pedicellis bracteatis, involucri calyculati foliolis sub-14 acutis lanceolatis subsphacelatis, ligulis sub-12 latis disco brevioribus subenerviis.—Buenos Ayres, Tweedie.—Scarcely a foot high. Leaves three, four, and five inches long, the radical ones on stalks equal to the

Radical leaves several, spathulate, somewhat fleshy, 3-5 lobed at the apex, lobes ovate obtuse, with a somewhat callous point; the base is dilated, and sheathing. Cauline leaves linear-subulate with a membraneous almost sheathing base. This seems

[page] 342

to answer to the Cineraria trifurcata, Spr., as far as do lower leaves are concerned, and it is from pretty near the same locality. We may observe, however, that the structure of the stem-leaves is very similar to that of our S. vaginatus. The flower is about an inch across. Involucre campanulate, scarcely calyculate, not sphacelate, of about 10-12 sharp glabrous leaflets, and with about as many yellow ligules.

2046. (40.) S. zosterælius, glaberrimus parvus annuus, radice fibrosa, caule scapiformi simplici folioso gracili monocephalo, foliis radicalibus linearibus obtusissimis enervibus basi dilatatis diaphanis subvaginantibus, caulinis sensim brevioribus subulatis, involucro lato-campanulati ecalyculati foliolis sub-14 acutis non sphacelatis, ligulis totidem brevibus obtusis estriatis integerrimis.—Margins of the Laguna de Ranco, near Valdivia; Bridges, (n. 632.)—This is a very remarkable looking plant, and has all the appearance of being an aquatic; the texture of the leaves is very similar to that of Zostera. Flower about three-fourths of an inch across, probably yellow where recent, but greenish where dry.

Darwin, Esq., (n. 367). Port Famine, Patagonia; Capt. King's Voyage.—This, and the two preceding, have a good deal the appearance of Culcitia. The present one is about a foot high, with long narrow radical leaves which have singularly long sheathing bases, and a scapiform stem. Capitulum about an inch in diameter.

in a young state to have been covered with a cobwebby wool, and on its falling away, the plant has the peculiar hoary tint which is seen on many species of Atriplex, and other marine plants, yet there is no appearance of tomentum or of scales or any mealy covering.

Leaves and involucres a good deal resembling those of the preceding C. leplophyllus; but the lobes of the former are not at all subulate, and the scales of the latter are much broader. In our var. β. the leaves and capitules are larger.

The capitula are too imperfect for description, but we believe the plant is certainly of this genus.

Latest Intelligence from Mr Gardner.

RIO DE JANEIRO, NOV. 18th, 1840.

MY DEAR SIR,—It gives me much pleasure to be able to inform you of my safe arrival at this place, with all the collections which I have been making since July of 1839. I remained in Minas Geraës till the beginning of October, and I arrived here on the first of this month. My headquarters in Minas, was Morro Velho, and from it I made several excusions, one of which was to the top of the Serra de Puda-do, which is the highest in Minas, and not with standing that my journey was made at the very worst season, I found some
