Uinta Basin Hookless Cactus
A small cactus nearly disappears into Uinta Basin gravel until a ring of vivid spring flowers briefly reveals it.
Artwork inspired by Maynard Dixon
Uinta Basin Hookless Cactus is a low globose plant with ribs, straight rather than hooked central spines, and pink to violet flowers. It occupies particular gravelly soils amid energy development, roads, invasive plants, and off-road disturbance.
Scan from existing roads or trails, use binoculars or zoom, and never handle flowers or test whether a spine is hooked. Precise locations should remain private. Search from established routes during spring bloom, when the small cactus is easiest to notice without approaching.
