Purshia tridentata is a shrub in the genus Purshia, and family Rosaceae. It is native to mountainous areas of western North America. [1]
Common names include antelope bitterbrush,[2] antelope brush, buckbrush, quinine brush, and less commonly deerbrush, blackbrush, and greasewood. Some of these names are shared with other closely related species.
Distribution
The plant is found from southeastern British Columbia in the north, east to Montana and Wyoming, south to New Mexico, and west in California.[3] It grows on arid mountainsides and slopes.
In California it occurs between 700–3,400 metres (2,300–11,200 ft) above sea level, including in the Peninsular Ranges, Transverse Ranges, and Sierra Nevada, and southern Cascade Range.[4][5] Further north it occurs at lower elevations, such as at 320–1,065 metres (1,050–3,494 ft) in British Columbia.[6]
