To Daniel Oliver 18 December 1874
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.

- … r F. could judge this. It ought to be done neatly. — The extreme marginal Hairs are long-headed; whether on this scale the difference could be represented, I know not. — Secondly would you put little fly on exact middle of leaf, & after Hairs are well clasped get a drawing made on same scale. Thirdly, perhaps, sketch of leaf of Dionæa, just to interest Reders. I shall have copied from Trécul the minute structure of Hairs. — My dear Sir | Yours very sincerely | C. Darwin …

Thanks for information and extracts.
M. A. Curtis, quoted in ["Dionaea"] Penny encyclopedia [(1837) 8: 508], gives the only full account of Dionaea.
Concurs in DO’s explanation of Dionaea footstalk cells, which CD took for stomata.
Is using carbonate of ammonia as a substitute for flies and colour change in glands as index of action on Drosera. Suspects other nitrogenous compounds do not act till decomposed into carbonate of ammonia. Beginning to write Drosera paper. Action of nitrogenous compounds.
