Mr. Darwin notices a similar and, if possible, more curious structure in a species of catasetum.

This conjecture as well as other conclusions drawn by Darwin from catasetum have been confirmed by Cruger-assuredly the best proof of the acumen with which the wonderful floral structure of this "most remarkable of the Orchids" was interpretated far from its native habitat.

As is shown by what we have said about catasetum, other problems in addition to those concerned with fertilisation are dealt with in the Orchid book.
