Summary

Discusses heterostyly in Hottonia.

Criticises L. C. Treviranus’ statements on Primula longiflora’s having short-styled form.

Describes his results with crossing different coloured primroses. Will let CD, when he reads his paper, decide whether his finding white and red varieties perfectly sterile when crossed, yet fertile inter se, ought to be published.

Difficulty in getting his orchid paper published in Edinburgh New Philosophical Journal.
