Maurandia semperflorens = scandens. Sept. 8th

Young shoot made two circles in 3° 32'. ∴ each in 1°. 46'.— Petioles sensitive to loops of threads — climbs exactly like other species — Put loops of thread & strong & stick against young peduncles. yesterday & today, I can see no clasping movement—

I think certainly 5 inch loops of strong cause considerable curvature in peduncles.— Better Taller climber, apparently than other species

Sept 9th & 10 Shoots not sensitive to rubbing — as might have been expected from Lophospermum & what follows—

I shd not have noticed this species, had it not been for following unique case.— Two flower peduncles in bud, from extreme tip to axis base 1 1/2 inch in length were observed under bell-glass & were in constant movement—

Sept 12th: Upper one moved, chiefly downwards & t. in curved crooked course, making little crooked circles or ellipses, & one moved a good deal to west. — The lower flower bud did not move in so crooked a course & moved almost vertically downwards & in night both some way upwards — I shd have imagined from position of plant that both avoided light; but next day showed this not the case

Sept. 13th. Upper one moved less in space & (in fact very little indeed) The lower bud made 3 narrow vertical irregular ellipses, moving a little to east, in 7° 10; each on average in 2° 23'; and at least 1 1/2 more circles in the next 3° 46'; which is at nearly same rate. The upper flower-bud also made very similar, but fewer ellipses. — Hence we must admit that these young flower-buds

How will old flowers behave??

Must introduce in both Summaries — Strike out passage after.

Passifloraceæ.—

(Movement & sensibility by some correlation of growth seem to have passed from shoot & petioles into peduncles. —)

Sept 27' & 28 A.m — young peduncle made all day very small circle— An old bud, just coloured & when expanded motionless —

Oct 27th Though favoured by pea-sticks & many plants, peduncle in not one case grasped Twigs.— If other Scroph. had flower tendrils, the power might have been a remnant as it is can hardly be so— nor is it of any use — a correlated faculty which might be worked in for good—.

spontaneously revolve in very small ellipse & sometimes take independently of light much larger movements

I was led to these observations by Mohl's statement that M. scandens (a syn by Steudel of this species) acts like tendril— I have not seen this, & am much surprised for flower peduncles generally attached to arise from stem already recurved by petioles.—

Sept. 14th at 11°. 47' rubbed upper side of one above peduncle & lower side of other in 1°. 15' neither bent again rubbed them several times with twig by 3° both bent towards rubbed side.

At 5° both nearly straight again— They became only slightly bent— so with loops of thread & strong several times; never nearly clasped

[98]

Give Mohl whole sentence [insertion:] He refers to peduncle of Valisneria to Tendrils — say never saw or could make one act — nor wd it be of use for position; except in hanging branches — Therefore following facts are curious — spont. movement & irritability—

No more apparent use that spont movement of Hedysarum or irritability of primrose or oxalis— But might be utilised if carried a little further on or perfected — Peduncle after touching often become permanently flexuous & this I presume has misled Mohl & is mentioned as a Botanical character

Young [illeg] shoots hardly yet bear flower-buds—

I put grand plant to branched twigs.

them; only slightly bent, whereas same loops of thread were clasped by the petioles with which they accidentally came in contact.—

Sept 15th I rubbed same 2 peduncle on opposite sides., both exteriorly to each other & after two rubbings they just diverged in perceptible manner.—

Sept 15th A thin upright stick pressing all day on same 2 peduncles caused no flexure; nor did it on former occasion.—

Generally 5 inch strong does nothing; but occasionally seems certainly to cause flexure.

Sept 20th rubbed several times lightly 2 peduncles, one on upper & one on lower side.— (these were younger than last & under 1 1/2 inch in length) & they became in 4 or 5 hours, greatly & conspicuously bowed. Some older ones did not become bowed. There cd. be no doubt—

[4v]

The above straightened themselves in 24° to 30°

Sept 20' Two peduncle only .3 in length bent from light rubbing — now this cd be of no use.

It is strangely capricious how loops of 5 & 10 inches of string act— I believe young alone are sensitive— —

Could Mohl's "scandens" (synonym by Steudel) be a distinct var. or species? My plants, though raised in autumn grew most vigorously.—

Mine certainly never acted as tendrils.—

Sept. 21— Two other peduncle above 3/4 of inch in length rubbed curved conspicuously towards each other became bowed & chord moved nearly 90°. — Rubbing far more effect than 5 inch loops of string — wd never clasp a stick put along-side
