Discussion | Species 1. Gilmania is restricted to the valley edges and low mountains surrounding Death Valley in Inyo County. In a “good” year, tens of millions of plants carpet the area, giving the edge of the valley a ring of golden yellow. Each individual produces thousands of flowers, and seed set in the plush years is enormous, thereby assuring long-term survival even in this harsh environment. The genus is allied to Eriogonum subg. Ganysma. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
