Summary

Thanks for CD’s ["Fertilization of orchids", Collected papers 2: 138–56].

Although Thomas Meehan’s paper ["Variations in Epigaea repens", Proc. Philadelphia Acad. Nat. Sci. (1868): 153–6] shows great variability in this genus, JTM sees a need to qualify the generalisation that there is as much variation in the wild as under domestication. He knows no evidence for a constant proportion between variability in the wild and under cultivation.

Observations on correlation between leaf size and exposure to sun and shade.

Has evidence for two varieties of Ophrys apifera in England, which live in mutually exclusive colonies.
