XX.—Short notice of a Botanical Trip to the Highlands of Scotland. By Professor. J. H. BALFOUR, M.D.

THIS trip was made in August last, along with my friend Mr. Babington and several of my pupils. We first visited the Clova district, and collected most of the rare alpine plants which are known to exist in that part of the Grampian range. Sonchus alpinus was found in a new locality in Glen Dole. The cliff on which Astragalus alpinus used to be found abundantly was examined with care, but only two or three specimens of the plant were seen.

From Clova we proceeded by Glen Callatea to Braemar, and made several botanical excursions in the neighbourhood of Castleton.

In our ascent of Ben Aven, one of the lofty mountains in the Braemar district, we examined a hill called Little Craigindal, which deserves notice on account of the number of good alpine plants which it furnished. The hill has a rounded contour, is readily accessible, and is composed of loose dry granitic and micaceous rocks. We were delighted to find upon it Astragalus alpinus in great abundance, both in flower and fruit. In some places the turf was actually composed of this plant. Carex rupestris was also growing beside it in large quantity. The other plants seen on this hill were, Thalictrum alpinum, Viola palustris, Silene acaulis, Dryas octopetala, Potentilla alpestris, Rubus chamæmorus, Alchemilla vulgaris, β. subsericea, Epilobium alpinum and alsinefolium, Sedum Rhodiola, Saxifraga oppositifolia, aizoides and stellaris, Cornus suecica, Hieracium alpinum and murorum, β. pulmonarium, γ. Lawsoni, Saussurea alpina, Gnaphalium supinum, Vaccinium uliginosum, Arctostaphylos Uva-ursi, Azalea procumbens, Pyrola media and secunda, Veronica Chamædrys, var. hirsuta, and V. serpyllifolia, β. humifusa, Trientalis europæa, Armeria maritima, β. alpina, Oxyria reniformis, Salix herbacea and myrsinites, β. arbutifolia, Betula nana, Listera cordata, Tofieldia palustris, Juncus trifidus and triglumis, Luzula spicata, Carex rigida, capillaris and pauciflora, Aira alpina, Lycopodium alpinum. The hill at first sight appeared to be very unpromising in a botanical point of view, not presenting any of those wet, disintegrating, micaceous cliffs, on which the best alpine plants in Scotland are found; and I have therefore de-
