Müller’s observations on orchids excellent.
The Origin converted him from a Linnean interpretation of flowers and mosses.

Plans to repeat CD’s orchid experiments.
Sends interpretation of the floral anatomy of Lopezia miniata.
Thanks for "Climbing plants" offprint and for references on fertilisation of flowers.
Considering the bounty of work already done, he is looking for something original to do.
Subularia does not grow in Westphalia.
Thanks for German version of Origin [1867].
