Summary:
Enthusiastic about JS’s work on Passiflora self-incompatibility.
CD quotes JS on rostellar pollen germination [in "Fertilisation of orchids", Collected papers 2: 77–8]. H. Crüger attributes it to ants’ carrying stigmatic secretion to pollen.
Homomorphic cowslip seedlings are, sadly, showing variation.
