Sends Ledum, the nectar of which catches many insects.
Describes his Primula varieties.
Has received Ledum with its captured flies.
"At present I care for nothing in this wide world except the biology of seedling plants."
Doubts Ledum warrants investigation. Glands probably serve only to protect the flowers against crawling insects, which would not cross-fertilise them.

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.

Thanks for sending Nature; plans to leave on 22 May; anecdote about Bernard.
Reports curious case of dimorphism in Rubiaceae. Encloses envelope containing bud samples.
