To J. D. Hooker   25 November [1877]1

Down, | Beckenham, Kent.

Nov. 25

My dear Hooker

Could you not get Mr Lynch to answer this note?2

Two Neptunia oleracea of last lot have germinated in a pan kept at tremendous heat.— What had I better do with them? I thought to put pan, as soon as any true leaves appear, in larger vessel & fill with water up to bases of true leaves; but I am of course quite ignorant how to treat them.—3

Ever yours | C. Darwin

Could you send me seeds of Oxalis sensitiva

I want to see cotyledons.—4


The year is established by the relationship between this letter and the letter from J. D. Hooker, 13 November 1877.
Richard Irwin Lynch was foreman of the propagating department at Kew; his reply has not been found.
See letter to J. D. Hooker, 6 November [1877] and n. 2, and letter from J. D. Hooker, 13 November 1877. Neptunia oleracea is water mimosa or sensitive neptunia.
CD discussed the movement of the cotyledons of Oxalis sensitiva (a synonym of Biophytum sensitiva) in Movement in plants. See also letter to W. T. Thiselton-Dyer, [20–4 August 1877] and n. 2.


Movement in plants: The power of movement in plants. By Charles Darwin. Assisted by Francis Darwin. London: John Murray. 1880.


Neptunia seeds germinated by applying great heat. CD wants advice of Kew gardener, R. I. Lynch, on how to proceed.

Printed public oration for CD’s Cambridge doctorate enclosed.
