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 siskiyouense is restricted to the ridge system that extends from the Scott Mountain area to the Mt. Eddy region of Siskiyou and Trinity counties. The vast majority of individuals in a population have a single involucre atop each flowering stem, but at lower elevations and in somewhat more protected sites the inflorescence may be umbellate. The Siskiyou wild buckwheat does well in cultivation if its soil requirements are fulfilled. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
