Glad to hear of MTM’s papers [? "On a peloria and semidouble flower of Ophrys aranifera, Huds.", J. Linn. Soc. Lond. (Bot.) 8 (1865): 207–11 and "Observations on the morphology and anatomy of the genus Restio, Linn.", J. Linn. Soc. Lond. (Bot.) 8 (1865): 211–55].

CD doubts the value, for origin of species, of parallels between peloria in "distinct groups".

Gärtner proved the stigma can select its own pollen from a mixture of foreign pollens. But much evidence shows varieties of same species are prepotent over a plant’s own pollen.

MTM’s father [William] believes that variation goes on for a long time once it has commenced.
