Much interested in MTM’s lecture at Royal Institution ["On the relation between the abnormal and normal formations in plants", Notes Proc. R. Inst. G. B. 3 (1860): 223–7].

Asks for information about crossing of varieties of peas. Describes his own experimental results: "the offspring out of the same pod, instead of being intermediate, was very nearly like the two pure parents; yet in one, there was a trace of the cross & the next generation showed still more plainly their mongrel origins".

Discusses crosses in sweetpeas and the difference between monstrosities and slight variations. Discusses peloric flowers.

Thanks for correction about furze.

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.
