From T. H. Farrer 20 September 1868
Eashing | Godalming.
My dear Mr Darwin,
I venture to add a few words to the Lobelia paper. if you happen to think it worth printing. The comparison of structure & function in neighbouring genera always seems to me most interesting.1 It was especially so in the Orchid—2
I was delighted with an opening bud of Campanula Rotundifolia— The adaptation of Corolla, anthers and brush is beautiful. The brush & its rows I found in Lindley—but he says Brongniart said it had nothing to do with fertilization—true enough as regards self fertilization3
I wont put any more questions to you though I am sorely tempted
Sincerely yours | T H Farrer
C Darwin Esq FRS
You wont be much more bothered with me as holiday & flowers are alike nearly over.
Sends an addition to Lobelia paper; admires adaptations for fertilisation.
