Johanneshowellia
Johanneshowellia puberula
Species 2 (2 in the flora).
With recognition of Johanneshowellia, all members of Eriogonum have their involucral bracts fused into a distinct, turbinate to campanulate or hemispheric, tubular structure. In Johanneshowellia, the four to seven, distinct, involucral bracts are arranged in a tight spiral. Each 0.5–1.2 mm, awnless, entire to deeply lobed bract subtends a flower-bearing pedicel. These involucral bracts are themselves usually obscured by inflorescence bracts that subtend each node. As a result, care must be taken to observe the true nature of the involucral complex. The genus is allied with Eriogonum subg. Oregonium.

Johanneshowellia puberula is infrequent to occasionally locally common. Populations are widely scattered from the Cottonwood Mountains of Inyo County, California, across northern Clark, southern Eureka, Lincoln, Nye, and White Pine counties of Nevada, into Beaver, Iron, Millard, and Washington counties in Utah.
