Range Extent20,000-200,000 square km (about 8000-80,000 square miles)
Rank Reasons
Limited to southeast California in the Mojave Desert and the foothills surrounding the Owens Valley (Riverside, San Bernardino, Inyo, Mono counties) and Nye County, Nevada. Apparently "scattered," "occasional to rare"; number of occurrences unknown. Occurs in desert scrub communities, on rocky to gravelly limestone substrates on mesas, slopes, and summits (600 - 1600 m).
Range Extent Comments
Occurs in southeast California in the Mojave Desert and the foothills surrounding the Owens Valley, in Riverside, San Bernardino, Inyo, and Mono counties; also occurs in Nye County, Nevada, near Rhyolite (Holmgren et al. 2005).
Occurrences Comments
The Consortium of California Herbaria reports 67 California collections, although most of these were made before 1970. Not tracked by the California Natural Diversity Database or the Nevada Natural Heritage Program, so recent field survey efforts have likely been limited.
Ecology & Habitat

Diagnostic Characteristics

Diagnostic features include the very broad siliques and seeds with wide membranous wings disposed in two distinct rows in the siliques (Rollins 1993). One of the most distinctive species in the genus (Rollins 1941).

Habitat

Prefers rocky to gravelly limestone substrates on mesas, slopes, and summits. Occurs on open sites (sometimes near near granite boulders) or in association with desert shrubs which may be used for support. Plant community is desert scrub, from creosote bush to sagebrush. 600 - 1600 m.
