To P. H. Gosse 5 June [1863]

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.

Summary
Encourages JS to continue work on coloured primrose. No one has noticed this since Gärtner. CD will send his own data for JS’s use and will read MS when ready. Advises JS to repeat experiments if evidence is weak – for his reputation’s sake and for satisfaction at fully establishing a fact.
