The Charles Darwin Collection
The Darwin Correspondence Project is publishing letters written by and to the naturalist Charles Darwin (1809–1882). Complete transcripts of letters are being made available through the Project’s website (www.darwinproject.ac.uk) after publication in the ongoing print edition of The Correspondence of Charles Darwin (Cambridge University Press 1985–). Metadata and summaries of all known letters (c. 15,000) appear in Ɛpsilon, and the full texts of available letters can also be searched, with links to the full texts.

Enquiring about cleistogamic flowers of Oxalis.
Discusses possible cleistogamic flowers in Oxalis.
Is it now thought that the spongioles of rootlets secrete carbonic acid which acts on bones and rocks?
Thanks for the information about the action of roots on rocks.
Thanks him for specimens.
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.
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.
Returning the plants DO had sent him from Kew
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.
