 Description

Though the three forms described below are very distinct there are intermediates and it seems inadvisable to create vars at present. It is not yet known how far the various forms noted are due to genetic differences and how far to modifications evoked by habitat conditions. No clear evidence has been adduced that hybridism plays a part. FL. 11–1. FT. 12–3.
