Annuals or perennials, 30-80 cm; taprooted. Stems lightly white-tomentose and/or glabrescent and green, minutely stipitate- or sessile-glandular beneath other in-duments. Leaf blades (not crowded, internodes mostly 5+ mm) oblanceolate-spatulate to obovate- or petiolate-spatulate, 5-10 cm × 10-20 mm (distal oblong to lanceolate or oblanceolate, 2-8 cm, slightly smaller), bases not clasping and decurrent 3-20 mm or clasping and decurrent 1-3 mm or not decurrent at all, margins flat to slightly revolute, faces bicolor, abaxial thinly white-tomentose, adaxial minutely stipitate- or sessile-glandular, otherwise glabrous or glabrate (bases of hairs persistent, enlarged). Heads in loose, corymbiform arrays. Involucres campanulate to turbinate, 3.5-4 mm. Phyllaries in 2-3 series, silvery white to tawny, oblong to oblong-ovate, (hyaline, shiny), glabrous. Pistillate florets 15-40(-64). Bisexual florets (1-)2-6. Cypselae ridged, papillate-roughened.

Leaves: Alternate, not crowded, spatulate or oblong to lanceolate or oblanceolate, 2-10 cm long, bases not clasping and decurrent, or clasping and decurrent, or not decurrent at all, the margins flat to slightly revolute, faces bicolor, minutely stipitate- or sessile-glandular, glabrous or glabrate, the undersides thinly white-tomentose. Flowers: Heads discoid, outer flowers slender and pistillate, the inner ones coarser and perfect, flowers all fertile, involucres campanulate to turbinate, 3.5-4 mm, phyllaries in 2-3 series, silvery white to tawny, oblong to oblong-ovate, membranaceous, shiny and glabrous, the heads in loose, corymbiform arrays. Fruits: Achenes ridged, warty. Pappus of capillary bristles. Ecology: Found from 5,000-7,500 ft (1524-2286 m); flowering September-November. Distribution: Arizona, New Mexico, Texas; Mexico.
