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.
Elevation: 90–1600 m.

Distribution

Tex., Mexico (Chihuahua), Mexico (Coahuila), Mexico (Durango), Mexico (Nuevo León), Mexico (Tamaulipas)
