Discussion | Antennaria anaphaloides is native to the northern Rocky Mountains and is characterized by whitish phyllaries, each with a black spot at the base. Some morphologic overlap occurs between A. anaphaloides and A. pulcherrima; the two occur in different habitats: A. anaphaloides grows in dry meadows and aspen forest openings; A. pulcherrima is usually found in moist willow thickets along streams (K. M. Urbanska 1983). Antennaria anaphaloides is closely related to the other members of the Pulcherrimae group (R. J. Bayer 1990; Bayer et al. 1996).

Antennaria stenophylla is a xerophyte in the Argenteae group. It is distinguished by relatively narrow leaves, heads in subcapitate clusters, and light brown, dingy brown, or olivaceous phyllary tips. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
