Character Abstract
Identification Comments:
Subspecies Comments:
Phenology Comments:Flowers mostly March through May.
Reproduction Comments:The species is an obligate outcrosser, dependent on bees and possibly other insects for successful reproduction.
Habitat Comments:Open, dry, spongy or powdery, often dissected ("badland") or hummocked soils with high gypsum content, often with well-developed soil crust, in areas of generally low relief on all aspects and slopes, with a sparse cover of other gypsum-tolerant species surrounded by Larrea tridentata, Atriplex, and Coleogyne ramosissima associations. On appropriate soil types, will often revegetate disturbances that have been allowed to recover if a soil seedbank remains.
Ecology Comments:
Inventory Comments:Surveys are substantially complete.
