Asks correspondent whether, when growing hollyhocks, he finds it necessary to space out the different varieties to prevent crossing and thus to obtain true seed [see Variation 2: 108].
Sends CD seeds of Cattleya crispa as requested [see Collected papers 2: 77–8].
Anticipates success for his attempts to cross orchids artificially. Has not had a single seed germinate from a pod that was not produced by artificial crossing.
Conducted crosses on Gladiolus varieties exactly according to CD’s letter. Flowers of same variety are self-sterile, whether from the same plant or not.

Provides evidence of self-sterility in Gladiolus.
Has observed three seed-leaves in some Dianthus seedlings.
Cannot cross, or grow from seed, Dielytra spectabilis.

Admits he may have drawn false inference from MTM’s division of peloria into two classes.
