Asks for more flowers of Epipactis palustris. Asks AGM to experiment on Epipactis.
Asks for specimen of Orchis latifolia and O. maculata. " … as some Botanists doubt whether they are distinct species it would be rather curious to show them insects distinguish them".
Found a lot of bee orchids. "All facts point clearly to self-fertilisation in this species; yet I cannot swallow the bitter pill."
Thanks for Epipactis palustris. Doubts moths are the visitants. Thanks for experiment.
