To Roland Trimen 31 January [1863]
Summary
Thanks RT for his letter and MS.
Is astonished by the different forms of orchids he describes.
Urges RT to describe and experiment with two or three of the more distinct genera.
"I believe, or am inclined to believe in one or very few primordial forms, from community of structure and early embryonic resemblances in each great class."
