Ecology & Life History
Help
Basic Description: White balls or domes, very inconspicuous. Cactaceae.
Diagnostic Characteristics: "Sclerocactus pubispinus generally has one dark red, robust, hooked central spine and two less stout, hooked central spines that are initially dark red and quickly fade to white, and flowers that are usually yellow to bronze. By contrast, S. spinosior generally has three stout, dark red central spines, the abaxial spine hooked, and flowers that are usually purple to cream. However, in juvenile (pre-reproductive) stages, the species are nearly indistinguishable." (Flora of North America Editorial Committee (2003).
Duration: PERENNIAL
Terrestrial Habitat(s): Forest/Woodland, Shrubland/chaparral, Woodland - Conifer
Habitat Comments: Rocky hillsides of woodland and upper desert mountains.  "Shadscale, sagebrush, winterfat, rabbitbrush, and pinyon-juniper communities on calcareous and dolomitic gravels and outcrops at 1800 to 1955 m" (Welsh et al. 2008).  "Light colored soils of limestone or dolostone origin, sagebrush and shadscale flats, pinyon-juniper woodlands; 1400-2200 m" (Flora of North America Editorial Committee 2003).
