Plants with strongly corrugate leaf margins from Ash Meadows, Nevada, are var. corrugata. Cronquist believed that corrugate-leaved plants from other areas in southern Nevada were a result of drying in press; D. L. Sanders (unpubl.) showed a gradual drop-off in corrugation of living leaves in the region to the east of Ash Meadows.
