Woody shrub, 0.3-3 m tall, branching pattern variable, stem strongly to faintly striate, densely adpressed pubescent. Leaves alternate, sessile, lamina narrowly elliptic to narrowly ovate, 10-25 mm long, 3-8 mm wide, densely adpressed pubescent above and below with many interspersed sessile glands, pubescence above and below usually sufficiently dense to obscure leaf surface, margin entire and unlobed, leaf apex mucronate, leaf base attenuate, leaf venation obscured by pubescence. Capitula usually solitary at ends of leafy branches, capitula pedicellate, pedicel 5-20 mm long, densely long adpressed pubescent, hairs drying white-yellow; usually with a single bract length 7-10 mm long, bract abaxially adpressed pubescent. Capitula discoid, homogamous; involucre broadly and shallowly campanulate, 9-18 mm in diam.; c. 40 phyllaries, multiseriate, width 0.5-1 mm, length 1.5-2.5 mm, phyllaries often abaxially pubescent with spreading hairs that dry yellow. Receptacle steeply conical at maturity, c. 3 mm diam. c. 2.5 mm tall, florets sessile. Florets hermaphrodite, c. 130 corollas yellow and four-lobed, tube 1.5-2.5 mm long, c. 1 mm diam.; distinction between tube and throat not conspicuous; lobes c. 0.4 mm long, acute and slightly inturned forming a hood; anthers drying white, c. 1.3 mm long, apical anther appendage rounded; basal anther appendages very short and triangular, anther collars inconspicuous and not pigmented. Mature achenes large, c. 3.4 mm long, c. 2 mm wide, with wings that dry pale brown, setulae usually absent, sparsely to densely glandular; pappus absent.
