Species Description - Erect shrub 1-2 m tall, with many lateral branches; stems pubescent to sometimes glabrate, irregularly angled. Leaf blades 4-15 x 1.5-6 cm, broadly elliptic to lanceolate, chartaceous to nearly coriaceous, the upper surface puberulent to nearly glabrous, the lower surface pubescent to puberulent, weakly glandular, the margins entire to subentire; petioles 0.5-1.5(-2.5) cm long, pubescent to densely so. Inflorescence a broadly rounded corymbiform panicle to 15 x 20 cm, with numerous heads. Heads 6-8 x 8-10 mm; involucre hemispheric to bell-shaped, 3-4-seriate, ca. 5 mm tall; involucral bracts many, pubescent, occasionally weakly glandular, becoming glabrous, especially toward tips of inner involucral bracts, the outer ones ovate, apically rounded, the inner ones linear-lanceolate, apically attenuate to acuminate, very innermost late-deciduous; receptacle glabrous, ca. 2 mm broad; peduncles 4-10 mm long, densely pubescent. Outer flowers with corollas 3.5-4 mm long. Inner flowers 15 or more; corollas 4-5 mm long, lightly glandular at tips. Achenes filiform, 0.5-1 mm long, weakly puberulent, ribs obscure or 1 or 2 apparent; pappus of ca. 10 bristles, ca. 4 mm long.
