Eriogonum apiculatum is restricted to the San Jacinto, Santa Rosa, Palomar, and Cuyamaca mountains of Riverside and San Diego counties. Two collections are discounted as to location: Hall 1025 (MIN), purportedly from the San Bernardino Mountains, certainly was labeled erroneously by the Parish brothers, who redistributed the sheet; and Jaeger s.n. (19 May 1940, DS, IDS, UTC, WTU) from “Falcon Flat” in the Little San Bernardino Mountains appears to be another of the small but significant list of Jaeger specimens with highly dubious label data. No such place is known in Joshua Tree National Park. The phase of the species named var. subvirgatum, with nearly sessile involucres, occurs intermixed with the typical expression. A yellow-flowered population was found at the eastern end of the San Bernardino Mountains, San Bernardino County. Recent attempts to relocate those plants have been unsuccessful, and they remain undescribed. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum fusiforme is widespread and common in southwestern Wyoming (Sweetwater County), eastern Utah (Carbon, Duchesne, Emery, Garfield, Grand, Kane, San Juan, Uintah, and Wayne counties), and adjacent western Colorado (Delta, Garfield, Mesa, Montrose, and Rio Blanco counties). In a “good” year, millions of individuals carpet the heavy clay flats and slopes (typically Mancos Shale), especially in Utah and Colorado. The plants can be so abundant and closely arranged that it can be difficult to walk through the tangle of stems and branches. This species is absolutely distinct from E. inflatum and no intermediates have ever been observed. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
