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.

Discusses unusual primula flowers and asks for details of Rawson’s experiments with gladioli. Asks for loan of Cypripedium but admits he will probably mutilate it.

Provides evidence of self-sterility in Gladiolus.

Has observed three seed-leaves in some Dianthus seedlings.

Cannot cross, or grow from seed, Dielytra spectabilis.

CD thanks the sender of a Cypripedium. He finds its pollination contrivances interesting.

Has observed the scarcity of humble-bees and subsequently of holly berries this year. But does not think humble-bees ever visit holly flowers, however plentiful they may be.
