Discussion | Antennaria neglecta is a sexual progenitor of both the A. howellii and A. parvifolia polyploid complexes and has one of the more widespread ranges among the amphimictic species in the genus in North America. Amphimicts generally have small ranges compared to those of the polyploid agamic complexes derived from them. Characteristic features of A. neglecta are its lashlike stolons that bear reduced leaves (except at the ends), flags on the distal cauline leaves, and basal leaves that are green-glabrescent with age (R. J. Bayer and G. L. Stebbins 1982). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Antennaria rosulata is easily recognizable by its silvery gray leaves, dense, humifuse growth form, and heads borne singly (R. J. Bayer 1987b). Its distribution is centered on the four corners area (Bayer and G. L. Stebbins 1987). It has probably contributed to the origins of some of the clones of A. rosea with low stature and low numbers of flowering heads that are found in Arizona, Colorado, New Mexico, and Utah.
