Physaria newberryi var. racemosa Rollins

Plants usually not mound-forming. Caudex simple or few-branched (some populations on shifting substrates with elongated branches). Styles less than 4 mm, shorter than fruit sinus. 2n = 8, 16.

Flowering Mar-May. Low elevation blackbrush, pinyon-juniper, Gambel oak, and ponderosa pine communities; 800-2400 m; Ariz., Nev., N.Mex., Utah.

Supposed differences between subspp. newberryi and racemosa do not hold up in light of recent collections that show a continuum in replum and raceme lengths.
