Shrubs, 30–150 cm. Stems much branched from bases, pubescent, often glanddotted. Leaves opposite; petioles 4–12 mm; blades 3-nerved from bases, broadly ovate to deltate, 10–60 × 10–30 mm, bases truncate, hastate, or subcordate, margins usually toothed (1–3 sets of sharp teeth near bases), rarely subentire, apices attenuate, faces minutely pubescent. Heads in loose, paniculiform arrays. Peduncles 5–40 mm, pubescent and sometimes glanddotted. Involucres cylindric to campanulate, 8–12 mm. Phyllaries 17–22 in 4–6 series, greenish, often purple-tinged, 4–5-striate, unequal, margins scarious (apices acute to acuminate or mucronate, minutely pubescent); outer lanceovate to narrowly lanceolate (glabrous or sparsely pubescent), inner narrowly lanceolate to linear (glabrous). Florets 13–25; corollas pale yellow-green, often purple-tinged, 7–8.2 mm. Cypselae 3–5 mm, hispidulous, strigose, or glandular-pubescent; pappi of 28–40 smooth or barbellulate bristles.
