STEPHANOMERIA

From Botanical Knowledge
Jump to: navigation, search


Because all the species of Stephanomeria have not previously been examined at one time, the present treatment provides the first unified picture of their variability, ecologic specializations, and geographic distributions. The genus includes six annual species (all in the flora) and ten perennial species (eight in the flora, one in the mountains of northern Baja California, and one known only from Guadalupe Island, Mexico).
