Leaves: Basal, 3-10 per plant; blades dull green, somewhat fleshy, 1-2 mm wide, linear to subfiliform, 5-25 cm long. Flowers: Yellow, solitary at the ends of scapes, and subtended by a spathe (large bract); flowers erect to slightly inclined; perianth funnelform, 2-3 cm, yellow with whitish tips or tinged with purple or rose; anthers orange; spathe papery, 2-3 cm, pinkish or purplish. Fruits: 3-lobed capsule, glabrous or slightly depressed, 1.5 cm in diameter with black, obovoid seeds, 5-7 mm long. Ecology: Found on sandy, gravelly, alkaline, or limestone soils from 4,000-6,000 ft (1219-1829 m); flowers June-August. Distribution: Ranges from Arizona to Texas and south into Mexico. Notes: Distinguished by possessing a beautiful yellow flower at the end of a scape, with many linear leaves emerging from the coppery or reddish tinged bases. Ethnobotany: Unknown, but other species in the genus have uses. Etymology: Zephyranthes probably comes from the Greek Zephyros, the Greek god of the west wind, and the Greek anthos for flower, while longifolia means long leaf.
