Stems usually pubescent, rarely glabrous, hairs strictly or irregularly spreading, rarely ± crisped, sparse to dense, mostly 0.3–0.5 mm. Leaf-blades elliptic, ovate, or obovate proximally, becoming narrowly so to nearly lanceolate distally, mostly 7–20 (–27) × 3–10 (–18) mm, venation usually prominently and firmly reticulate, occasionally obscure, surfaces with pubescence similar to stems, or hairs slightly longer. Keel sacs glabrous or with scattered, spreading hairs proximally, hairs not incurved in distal 1/2.2n = 18.
Phenology: Flowering spring–fall (year-round).
Habitat: Limestone or caliche, sandstone, shale, infrequently on gypsum, granite, or igneous substrates on ridge tops, slopes, roadcuts, canyons in juniper-oak woodlands, grassland, thorn scrub, desert scrub, canyon brush.
