The name Eriogonum angulosum has been applied to all of the members of its species complex except E. gossypinum. Since the 1950s, the name consistently has been applied to plants with long, exserted stamens and strongly angled stems of the Inner Coast Ranges (Alameda and Contra Costa counties south), the western foothills of the southern Sierra Nevada (Tulare County south), and the Central Valley (San Joaquin County south). The southern edge of the range is the northern foothills of the Transverse Ranges (Ventura and Los Angeles counties). The species can be common and occasionally abundant but rarely is weedy. A mixed collection (with E. gracillimum) from Barstow, San Bernardino County (K. Brandegee s.n., May 1913, UC), and two sheets of the species from San Diego gathered by Susan Stokes apparently in 1895 (B, SD) are discounted as to location. In late fruit, the bractlets at the base of the pedicel inside the involucres of Eriogonum angulosum often elongate and broaden into oblanceolate segments that fill the involucre. As a result, the involucre appears to have several rows of teeth. This feature may be seen also in E. viridescens, but typically the involucres there appear to have only two or three rows of teeth. This feature is seen rarely in E. maculatum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum pusillum is common to abundant but rarely weedy. It is found mainly in the northern Mojave Desert and in the Great Basin of the Intermountain West of California and Nevada, extending just into southeastern Oregon, western Utah, and northwestern Arizona. It supposedly was found near Wickenburg in Maricopa County, California (M. E. Jones s.n., 5 May 1903, POM), well out of the known range of the species today. The San Benito River canyon site in San Benito County, California (Mason 5543; UC), also is notably disjunct, and although the species has not been recollected there, that location record is more reliable. The Plumas County record is based on an 1880 Austin collection (NY), and the location should be regarded as questionable. Eriogonum pusillum is used as a food plant by the rare Mojave dotted-blue butterfly (Euphilotes mojave). Also, along with E. reniforme, it is an important food plant for juvenile desert tortoises (Gopherus agassizii). The Kawaiisu people of southern California gathered the achenes of E. pusillum, which were pounded into a powder and cooked into a mush or consumed dry (M. L. Zigmond 1981).
