Is pleased that CD has [Roland] Trimen to collect specimens of Cape orchids. Suggests directions for securing dry specimens of what he draws.
Identifies Disa barbata and D. Cornuta of the Ophridiae.

I am right glad to find you have got so capital a worker on Cape Orchids, which I have been longing to have investigated on the spot, from
sometimes a mere thread
and sometimes as as in Brownlia, nearly disappears altogether, & is adnate to the column.
In Satyrium the two spurres affair is a true labellum—the sepals & petals small & crowded together at the front of flower—the opposite to Disa.
Yours truly | W. H. Harvey
- f1 3966f.f1Harvey refers to Roland Trimen. Having read Orchids, Trimen sent CD a letter, probably early in January 1863, with which he enclosed a manuscript and sketches detailing observations he had made on a number of South African orchids. CD sent Trimen's sketches to Harvey, asking him to identify two unnamed species (see letter to Roland Trimen, 31 January ). Neither Trimen's letter to CD nor CD's letter to Harvey has been found. Harvey was the author of several works on the taxonomy of South African plants (see W. H. Harvey 1838 and 1859--63, and W. H. Harvey and Sonder 1859--65).
- f2 3966f.f2Harvey's initial response to Origin had been hostile (see Correspondence vol. 8, letter from W. H. Harvey, 24 August 1860, and Appendix VII). Harvey was more favourable to CD's views after reading Asa Gray's interpretation of Origin (A. Gray 1860a), which argued that natural selection provided evidence of purposeful design in nature (see Correspondence vol. 8, letter to Asa Gray, 26 September , n. 14). CD sought to strengthen this favourable impression by ensuring that Harvey received a copy of Gray's pamphlet Natural selection not inconsistent with natural theology (A. Gray 1861a; see Correspondence vol. 9, letter to Asa Gray, 23 [January 1861], and Appendix III). Harvey was also on CD's presentation list for Orchids (see Correspondence vol. 10, Appendix IV).

- f4 3966f.f4CD enclosed this copy, made by Henrietta Emma Darwin, with the letter to Roland Trimen, 16 February .
