Oxalis sensitiva

Dec. 6th 4 seedlings — some a week old & 2 other only 1 to 2 days old. r Sun was shining & well illuminated in Hot Case, & then put into dark cupboard in Hot House at 12º 10'— The Cots. owing to circumnutation held very different positions & I may add till 4º 20' continually changed their position in the dark, & at this hour were just beginning I believe permanently to close.— I will describe only 2 cases.

at 12º 10' thus [sketch] (1) à [sketch] (3)

12º 43' no change of any importance

1. 28' (1) somewhat raised above Horizon — almost closed

2º 13 (1) about the same. much more open

2. 58 almost Horizontal still more open

3. 25 about 25º above horizon almost closed

4. 20 more closed more closed.

It is clear that complete darkness after sun-light, in course of 4º did not act paratonically, nor prevent circumnutation— yet sensitive to touch & raps — what a contrast with Cassia.

There can be no doubt that jogging pot causes Cots to rises after about 10' & still more after 17'— after about 80' considerably open.— It was a prolonged jogging of about 5'.

At close of Bassoon notes by F some good observations well worth giving on rate of circumnutation with given time of Cotyledon-Hypocotyls free.

Sole case of same cot. standing vertically up & down in day time— so give

Dec. 7' 4 seedlings with position of Cots. sketched, pot carried on tray with no precautions to my Study, so got moderately jogged: this at 12º 43'.—

After 11' I will describe 2 some cases (No 6) Cots at first greatly below horizon at least 30º after 11' horizontal— after 17'; about 45º above horizon; after 47' the 2 cots together formed only an angle of 45º, so each had risen about 82º. in course of 1º addition 40' additional more open.

(No 2. at first a little below horizon, say 10º horizontal after after 11', after 17' about 30º or 35º above horizon; after 47', 2 cots about 90º apart, this older seedling; so each had risen about 55º; in 40' subsequently opened a little—

(Nor 3. at first horizontal after 11' greatly risen, after 17' completely shut, so in 17' each had (younger seedling) risen 90º; after 47' still closed & after 40' additional still closed.)

Nor 4 at first considerably raised, after 11' more raised; after 17' almost shut; after 47' do — after additional 40' more open.
