Summary:

Can only conjecture that the problem occurs because the plant is not living in its natural conditions. Refers to what he said on Acropera [in Orchids]. Many plants under culture have sexual functions altered.

Asks PHG to look at bee Ophrys at Torquay to see if pollinia are ever removed. "It is my greatest puzzle."

Summary:

PHG’s hypothesis [regarding the self-fertilising mechanism of Stanhopea] may prove quite true, but CD suggests that PHG should observe another spike to make sure. CD will observe his Stanhopea if it flowers.
