Asks for a specimen of Pinguicula.
Has some Utricularia minor for CD. Has found the bladders on U. vulgaris are not floats.
Thanks CD for book [Descent, 2d ed.].
Suggests experiments to try [with Nepenthes]. Asks JDH to test whether cabbage seeds and peas exposed to the ferment germinate.
Sends reference on Pinguicula [for CD].
Asks WED to visit Winchester soon and collect Utricularia for him
Has "given the slip" to Nepenthes, but is setting a plant up in an enclosure for special observation.
Has some splendid Sarracenia and will perform any miracle regarding them CD puts him up to.
Charmed with CD’s account of Pinguicula. Would like to try whether Lychnis has the same use of viscid fluid.
Has written for English Utricularia for CD.
Describes leaf movements of Pinguicula and Drosera in capturing prey. Notes effects of ammonium carbonate on leaves.
Cobra poison is a stimulant to protoplasm. Poison acts very differently on cilia and protoplasm of Drosera.
Sends further details on Pinguicula reference.
Thinks Frank and he have worked out Pinguicula well and they long to attack Utricularia. Tried several plants with sticky glandular hairs; some few absorb ammonia, but the greater number do not. If JDH sends plant or seed of Lychnis CD will examine it to see whether it catches many flies. Asa Gray has written him much about Sarracenia, with a specimen showing the splendid dodge by which ground insects are enticed up and then drowned. Describes how it may be investigated, to see whether it absorbs decayed matter from flies, or ammonia thus generated.
Sends results of his observations on Nepenthes. Would be grateful for any hints for further observations.
Has read THF’s article on Coronilla [see 9400] – "a very curious case"; is troubled by C. emerus.
