Ecology: Found in a range of habitats from pine forests and woodlands to pine-oak woodlands, canyon bottoms to ridges, from rocky soils and ridgetops to deep soils in dry canyons from 5,000-9,000 ft (1524-2743 m), flowers July-October. Distribution: Ranges across Arizona to Colorado, south to southern Mexico and into Baja California. Notes: Not well described in recent literature, this species description draws from Duke 1961, who characterized the holotype D. leptophylla as being D. leptophylla var. leptophylla. Distinguished by the bifid petals and the generally linear leaves. Ethnobotany: Unknown Etymology: Drymaria comes from the Greek drymos for forest, while leptophylla means with slender leaves.
