Plants with relatively elongate basal leaves and cauline leaves little reduced distally (identified as Erigeron delicatus) are much different in general aspect; intermediates bridge the morphologic extremes. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Erigeron nanus is unusually variable in leaf vestiture. The tendency (especially in Cassia County, Idaho) for sparsely strigose adaxial and glabrous abaxial leaf faces is similar to that of the E. radicatus group; longer disc corollas and the strong tendency for unequal-length stem hairs, plus spreading-ciliate petioles, place E. nanus closer to E. disparipilus and E. poliospermus.
