Eriogonum brachypodum is variable in overall shape, peduncle length, and shape and size of involucres and flowers. Spreading plants with longish peduncles and narrow involucres occur in southwestern Utah and adjacent portions of Nevada and Arizona; this is the “parryi” phase of the species. Typical E. brachypodum is low and flat-topped, with the inflorescence up to 10 dm across. The involucres are usually sessile and campanulate rather than turbinate. The two phases intergrade completely and a taxonomic distinction is not warranted. Dried plants of the typical phase often are used as decorations. The species is common and even weedy in places. It occurs from Churchill and Pershing counties, Nevada, south through Mono and Inyo counties to eastern Kern and San Bernardino counties, California, then eastward through Nevada (Clark, Esmeralda, Lincoln, Mineral, and Nye counties) into southwestern Utah (Beaver and Washington counties) and northwestern Arizona (Mohave County). It is much more common in the Mojave Desert than in the Great Basin. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum ampullaceum is the Great Basin counterpart to E. mohavense of the Mojave Desert. It is found along the eastern edge of the Sierra Nevada in Mono County, California, mainly in the Bridgeport, Mono Lake, and Long Valley areas (south of Mammoth). It occurs also in Alkali Valley in Mineral County, Nevada, and to the south in Fish Lake Valley of Esmeralda County. The species recently has been seen as a roadside weed along U.S. Highway 395 near Big Pine in Inyo County, California. The plants typically are infrequent and only occasionally locally common. The species is considered “sensitive” in Nevada. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
