The volume CUL-DAR66 contains notes on 'bloom'. Francis Darwin explained: "His researches into the meaning of the 'bloom,' or waxy coating found on many leaves, was one of those inquiries which remained unfinished at the time of his death. He amassed a quantity of notes on the subject". LL3: 339. See an Introduction to these folders by Christine Chua & John van Wyhe.

Aug 21'— /77/ Abinger. [illeg]
Hedysarum coronarius? (French Honeysuckle white)
All leaflets well silvery above, wetted below.
[sketch] 1 or 2 pair of smaller leaflets
At night the lateral leaflets approach each other but do not touch, so as as to stand almost vertically, & the terminal leaflet bends upwards, as in annexed diagram, in which the terminal leaflet was during day in the same plane with the petiole
[sketch]
Whether petiole moves upwards I do not know.
Aug 23d I shook & syringed 2 vine leaves & cd perceive no trace of movement of leaflets
Aug 24th. Marked with parallel little twigs 3 leaves springing from ground, & could perceive no change during sleep of their petioles.— What a contrast in movement with Hedysarum gyrans.
