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.
Asks DO to return enclosed post-card with locality of Genlisea aurea specimen that DO had sent.
