Summary

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. Requests specific plants to test for dimorphism and would welcome examples from any family in which he has not encountered dimorphic species.
