Summary

Germination of Cactaceae; CD wants seeds. Site of action of growth-stimuli.

Summary

Wants Trifolium resupinatum for "bloom" experiment.

Summary

Movements of cotyledons of Oxalis.

Francis Darwin at Würzburg with Julius Sachs.

Summary

Asks for some seeds of coniferous plants. Wants to examine their first leaves.

Summary

Heliotropism. Requires some plants for experiments.

Summary

Thanks for plants.

Thanks R. I. Lynch for information about "bloom" on leaves.

WTT-D should not write to Mr Smith about plants near seashore.

Summary

Wants some apheliotropic plants for experiments.

Summary

Asks specific questions on looking after plants of Dionaea. [The correspondent’s replies to the questions are written beneath them.]

Summary

Movements in cotyledons; outlines tracing technique. [A tracing of movements of red cabbage cotyledon enclosed.]

Summary

WTT-D’s statement perverted by Times [4 May 1878, p. 6, on WTT-D’s Royal Institution lectures on vegetable morphology].

S. H. Vines’s work on light inhibition of Phycomyces hyphae ["The influence of light upon the growth of unicellular organs" (1878), Arb. Bot. Inst. Würzburg 2 (1882): 133–47] suggests heliotropism in green plants is independent of, and more primitive than, photosynthesis.

Heliotropism in aerial roots.

Frank Darwin’s work.

Summary

Thanks for plants and seeds; requests for more to test Sachs’s notion on "bloom".

Summary

Requests seeds for experiments he and Frank are doing on automatic movements of cotyledons.

Summary

E. R. Lankester has been unfairly blackballed at the Linnean Society. He is to be proposed for a second time, with CD seconding the proposal. Urges ARW to attend the ballot.

Summary

Discusses fairy rings.

Summary

Has offered Carl Semper the writing machine.

Speculates on the mechanism of movement in plants and their reception of and response to stimuli.

Summary

Will call on addressee when he is next in London.

Summary

Extract from Athenæum 11 May [1878], p. 606, of R. I. Lynch on germination of the provision tree.

Summary

Describes the germination and early growth of Megarrhiza about which AG has been misinformed. The tubular petioles act functionally like a root.

Ipomoea did not germinate.

Summary

Cactus and Cycas seedlings: observations and queries.

Working hard on plant movements.

Summary

It would be interesting to prove that some plants feed on decayed animal matter whilst others like Drosera can digest fresh animal matter. Suggests the method for observing this.
