Annuals or perennials, 20-50 cm; taprooted. Stems loosely and densely woolly-tomentose (hairs usually with reddish or purplish cross walls), not glandular. Leaf blades linear-oblanceolate to linear-lanceolate, 2-6 cm × 2-7 mm, bases not clasping, decurrent 3-15(-20) mm, margins weakly and narrowly revolute, faces concolor to weakly bicolor, tomentose (hairs commonly with reddish or purplish cross walls), not glandular. Heads borne singly or in terminal glomerules or corymbiform arrays. Involucres turbinate-campanulate, 5-6 mm. Phyllaries in 4-5 series, usually brownish to tawny, rarely slightly rosy (opaque, shiny), ovate-lanceolate to lanceolate, glabrous. Pistillate florets (25-)30-49. Bisexual florets (1-)3-6. Cypselae ridged, papillate-roughened. Flowering Aug-Sep. Open woodlands and chaparral [wide ranging habitats in Mexico, agricultural land to oak and pine woodlands]; 1600-2300 m; Ariz., Tex.; w Mexico. Pseudognaphalium arizonicum is superficially similar to P. stramineum in its narrow, concolor leaves; P. stramineum has non-decurrent leaves, light yellowish phyllaries, and more pistillate and bisexual florets.

Duration: Annual Nativity: Native Lifeform: Forb/Herb General: Herbaceous annuals, to 50 cm tall, stems loosely and densely woolly-tomentose, not glandular, the plants taprooted. Leaves: Alternate, linear-oblanceolate to linear-lanceolate, 2-6 cm long, 2-7 mm wide, the bases decurrent, margins entire, weakly and narrowly revolute, faces concolor, tomentose, not glandular. Flowers: Heads discoid, medium-sized, the outer flowers slender and pistillate, the inner ones coarser and perfect, flowers all fertile, receptacle , without leafy bracts, involucres turbinate, 5-6 mm long, strongly overlapping, phyllaries in 4-5 series, brownish to tawny or rosy, ovate-lanceolate to lanceolate, scarious throughout, heads 30-50, borne singly or glomerate at branch tips. Fruits: Achenes ridged, warty. Pappus of capillary bristles. Ecology: Found in pine forests, open woodlands and chaparral, from 5,000-7,500 ft (1524-2286 m); flowering August-October. Distribution: Arizona, Texas; Mexico. Ethnobotany: Unknown Etymology: Pseudognaphalium is false gnaphalium, the former genus name, while arizonicum means of or from Arizona.
