To Asa Gray   4 December 1876

Plans to republish his paper on dimorphism with additions [Forms of flowers]. Is convinced it is necessary to compare pollen-grains and the state of the stigma to recognise dimorphic plants.

To Asa Gray   8 March 1877

Summary

Leucosmia burnettiana is in all probability dimorphic. Thinks Gilia is truly heterostyled and Phlox subulata was, perhaps, once heterostyled. Has good evidence of heterostyly in 39 genera from 14 families.
