Flowers: White or rarely red with 4 open and spreading petals, 4-8 mm long, opening at dusk, sepals 4, 4-8 mm long, reflexed singly or in pairs, longer stamens opposite sepals, anthers attached at middle, pollen grains 3-angled, stigmas hemispheric, hypanthium 4-8 mm long, inflorescences spike-like and nodding with inconspicuous bracts, flowers often absent at the proximal nodes. Fruits: Capsules cylindric and tapered to the tip, to 35 mm long and 1-3.5 mm wide, curved outward to strongly wavy and twisted, persistent, tardily dehiscent. Seeds 1-2 mm long, obovoid to oblanceoloid, minutely pitted in rows, pale to dark brown and minutely pi Ecology: Found on sandy soils on slopes, in washes and desert scrub communities, from 250-4,000 ft (76-1219 m); flowering February-May. Distribution: Arizona, California, Utah; Mexico. Notes: Keys for the subspecies are the inconspicuous bracts of the infloresences, the outward curving fruits 2-3.8 mm wide, and the stout plants with glabrous stems and leaves, arising from a well-developed basal rosette.
