Var. lactea, while varying greatly in size, remains rather uniform in most characters throughout its whole range. The glandular hairs of the infl. distinguish it immediately from all forms of O. crosbyi, with the distribution of which it overlaps; vegetatively the latter sp. differs in its generally more elongate lvs with rather more sharply toothed margins and in having hairs on the undersurface of lvs between as well as on veins.
