14. VI. ’64

My dear Sir.

I shall be glad to do the little diagram as you request.—1 Have you read von Mohl’s “Bau und Winden der Ranken und Schlingpflanzen”?2 I have not read it myself,—but he refers to it in his “Anaty. &c. of the Vegetable Cell”.3 when he refers to the “enigmatl” phenomena of twiners,—the internodes of which he describes as (when they have attained a certain age) beginning to curl so that the upper parts are “continually carried round in a circle like the hand of a clock,” &c. &c.

Have you—to spare—a copy of the photog. of wh. one reached Dr. Hooker a few days ago,—reminding him of Moses,4 &c. I shd. much value one.

Yours very sincerely | Dal. Oliver.


In his letter of [c. 10 June 1864], CD had asked Oliver to draw a diagram to accompany his paper ‘Three forms of Lythrum salicaria, which was to be read at the meeting of the Linnean Society on 16 June 1864.
The reference is to Ueber den Bau und das Winden der Ranken und Schlingpflanzen (On the structure and coiling of tendril and twining plants) by Hugo von Mohl (Mohl 1827). An annotated copy of Mohl 1827 is in the Darwin Library–CUL (see Marginalia 1: 590–4).
Mohl’s work Grundzüge der Anatomie und Physiologie der vegetabilischen Zelle (Mohl 1851) was translated by Arthur Henfrey as Principles of the anatomy and physiology of the vegetable cell (Henfrey trans. 1852). Oliver refers to Henfrey trans. 1852, p. 157. An annotated copy of Henfrey trans. 1852 is in the Darwin Library–CUL (see Marginalia 1: 589–90).
