To J. D. Hooker 9 October 1874

Oct 9th 1874
My dear Hooker
In your Edit of Decaisne, Byblis from Australia & Roridula from S. Africa are given under the Dros: & Lindley adds Sondera of Lehm.1 As I have examined 4 genera, I should very much like to see a leaf of any or all of these genera. But I do not know what I am asking, for these plants may be excessively rare; but if you can spare a leaf (especially one with the hairs or tentacles incurved) I could soak it, gum it on paper & return it. I suppose you could get one of yr assistants to look at the plants & settle whether a leaf could be spared. By the way in Descaisne I see “Morocco” added to the range of Drosophyllum, & “Bengal” to Aldrovanda; I presume that the square brackets mean that you have added these localities.2
Will you ask Oliver3 to do me a great favour; viz: to consider whether there is any anomalous sp of Utricularia, especially an epiphytic or marsh sp, & send me if possible an atom of a rhizome or branch, that I might soak it & look at the bladders.4 I have studied so carefully those which I possess, that I desire much to see how far their structure ever differs. No doubt Oliver can tell me whether other sp, besides U. montana, have tubers on the rhizomes.—5
I am keeping the 3 buds of Aldrovanda under 3 different temperatures, & they are all looking pretty well, so that I have hopes of the leaves opening.6 I am afraid this letter will bother you. Yours affectionately | Ch. Darwin
