| Description |
mountain rocktansy, Sphaeromeria cana, California, White Mountains, Cottonwood Basin, Granite Meadow, Fishlake Valley drainage, elevation 3025 m (9925 ft). Another rock outcrop species found with the Jamesia posted earlier, this species is endemic to the Great Basin mountains of Nevada and adjacent southeast Oregon and eastern California, including the southern Sierra Nevada and northern Mojave Desert, up to about 3600 meters (12000 feet) elevation. The species is a calcifuge, liking granite crevices best, but found on other rock types as long as they have no significant carbonate content. In 1984 I had to backpack to some pretty remote granite outcrops to document this species in the White Mountains for the first time, and thought I had some unnamed sagebrush species until Mary Dedecker set me straight. It has since proven to be fairly frequent in the White Mountains, but is a late-flowering species, and when not in flower it looks exactly like sagebrush from a short distance, so had gone unnoticed here for a century. The similarity to sagebrush is no accident, as recent DNA studies have shown that the 9 species of Sphaeromeria originated from within Artemisia. For those who want to lump an ever bigger Artemisia, the name Artemisia albicans is available for this species. |
