Eriogonum spathulatum is fairly common in west-central Utah. The typical expression, tomentose plants with ochroleucous flowers, occurs mainly in Iron, southern Juab, Millard, Piute, Sanpete, and Sevier counties. Plants with pale yellow to yellow perianths are seen infrequently in a few populations; these are always intermixed with plants bearing non-yellow perianths. Mixed populations of plants with either tomentose or glabrous flowering stems and inflorescence branches occur on gravelly limestone ridges in Beaver County; those with glabrous flowering stems and inflorescence branches have been separated recently as var. kayeae. In aspect, these approach Eriogonum artificis, a plant of sandy volcanic soils. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
