Source of text:
DAR 92: A38–9
Summary:

Thanks RC for photograph and for papers, which are of highest interest to CD. He is not fully convinced about the rose by RC’s graft-hybrid paper [Bull. Congr. Int. Bot. & Hortic. Amsterdam (1865): 65–80]. Still retains faith in his own view that no plant is perpetually self-fertilised.
