Summary

Returns insectivorous plants to Kew, with questions about their range. Most species seem to have remarkably confined ranges.

Asks for a Bengal Aldrovanda leaf so that he can see whether it differs from the German species.

Roridula interested him extremely.

Summary

Thanks him for specimens.

Summary

Sends information about Indian and Australian species of Aldrovanda, Roridula, and Byblis.

Summary

Asks four favours: sort out confusion about the name Byblis gigantea or grandiflora; can he see dried specimens of Genlisea ornata; is there a more recent list of Drosera spp. than Steudel 1841; are there at Kew any dried specimens of Utricularia montana collected from the plant’s native haunts.

Summary

Sends capsules with results from Genlisea specimens and fragments of Polypompholyx.

Summary

Sends specimens of Byblis, Roridula, and Utricularia for CD’s examination.

Summary

Sends Utricularia montana and Byblis species.

Drosera census numbers 100 species.

Genlisea distinguished from Utricularia.

Summary

Thanks CD for his letter of 1 Jan 1875. Will send a paper on the genus Volvox ["Die Entwicklungsgeschichte der Gattung Volvox", Cohn Beitr. Biol. Pflanz. 1 (1875) Heft 3: 99–115].

Informs CD of his discoveries of the "house"-building capacity of Difflugia, one of the lowest forms of organism.

Sends CD his writing on Aldrovanda and Utricularia, which he is welcome to use in his forthcoming book [Insectivorous plants].

Has observed a Dionaea fertilised without insect aid.

Summary

CD’s observations [for Insectivorous plants] seem to indicate that the same species of Genlisea may bear two kinds of bladders, so he asks for rhizomes and leaves of three species to test this possibility.

Summary

Comments on R. L. Tait’s claimed isolation of digestive ferments from Nepenthes.

Summary

The generic name Genlisea must be preserved for Utriculariaceae with five-part calyces.

Summary

Returning the plants DO had sent him from Kew

Summary

Information about various species of Utricularia.

Summary

Hopes JDH will beat Sir Douglas Galton.

Continues to work on insectivorous plants.

Summary

Discusses the contraction of hygroscopic bundles in seed-pods,

and a paper by Hugo von Mohl ["Über dimorphe Blüthen", Bot. Ztg. (1863): 309–15, 321–8] in which he discusses Oxalis and determines that Fumaria is a necessarily self-fertilising plant.

Summary

Oliver will attend to his letter.

Tells of discovery and rediscovery of Aldrovanda.

Asks what CD thinks of "old Pritchard’s discourse" [C. Pritchard, Natural science and natural religion (1874)]. Does not affect evolution at all. It does affect the rather unprofitable doctrine of materialism.

His plans for the Royal Society Presidential Address.

Summary

CD’s Utricularia findings – bladders, subterranean roots, and insects decomposing in them – a grand discovery.

Summary

Thanks Balfour for Corydalis seed

and sends a photo of himself.

Summary

DO’s observations on polymorphism in Primula and Campanula. CD recognises three classes of dimorphism, as in Primula, Thymus, and Campanula and violets.

DO’s Campanula paper and Royal Institution lecture [Not. Proc. R. Inst. G. B. 3 (1858–62): 431–3].

CD’s interest in Fumariaceae from A. Gray’s comments on "selfing".

Bees bite holes in flowers when same species grows in high density.

Organisation of CD’s notes.

Summary

Thanks JDH for Asa Gray’s interesting letter.

Would like JDH’s copy of Coral reefs. Needs it for corrections for a new edition. Cannot buy one.
