Erigeron flettii differs from E. grandiflorus in having fewer, wider, consistently white rays, broadly spatulate basal leaves with bases constricted into narrow petioles longer than the blades and apices rounded or obtuse, less dense involucral vestiture, and strongly barbellate pappus bristles. It is known only from the Olympic Mountains. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Erigeron velutipes is known from a single locality in southern Arizona. It is closely similar to E. lobatus and E. piscaticus. The group needs detailed study. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
