Discussion

Antennaria soliceps is a high-polyploid apomict known only from limestone talus at treeline in the Spring (Charleston) Mountains, Nevada (R. J. Bayer and T. M. Minish 1993). It is probably most closely related to A. aromatica, an amphimictic species occurring in the northern Rockies, and is characterized by a cushion-plant growth form and heads borne singly (Bayer and Minish).
