To T. H. Farrer 6 May [1869]
Summary
Dislikes the use of the term "degradation" as applied to the closed flowers of Viola species. Species with such self-fertilising flowers also have flowers adapted for crossing. The development of closed flowers adapted to ensure a sufficient stock of seed is progressive.
