Plants 0.3–1 m. Stems: branches gray-brown to redbrown, densely villous; branchlet color obscured by hairs, densely villous. Leaves: stipules sometimes marcescent, foliaceous (sometimes obscured by hairs) on early ones, foliaceous and prominent on late ones, linear to narrowly elliptic, 2–17 mm, apex acute to caudate; petiole 1–9 mm, villous adaxially; largest medial blade (hemiamphistomatous), sometimes narrowly oblong, 27–74 × 8–24 mm, 2.1–3.9 times as long as wide, base rounded, apex acuminate, convex, or acute, abaxial surface densely villous or villous-silky, hairs straight or wavy, adaxial moderately densely villous, or long-silky to glabrescent; proximal blade margins entire; juvenile blade densely villous or long-silky. Catkins: staminate 14–26 × 8–14 mm, flowering branchlet 1–14 mm; pistillate stout or subglobose, 15–54 × 7–15 mm, flowering branchlet 2–19 mm; floral bract tawny, light-brown or bicolor, 1.2–2.2 mm, apex convex, hairs straight, wavy, or crinkled. Staminate flowers: abaxial nectary 0.3–1 mm; filaments distinct or partly connate, glabrous, or hairy on proximal 1/2. Pistillate flowers: adaxial nectary sometimes flask-shaped, (0.4–) 0.6–1.8 mm; stipe 0.4–1.8 mm; ovary obclavate or pyriform, very densely villous or tomentose, beak abruptly tapering to styles; ovules 10–20 per ovary; styles connate to distinct, 0.4–1 mm; stigmas slenderly cylindrical, 0.3–0.8 mm. Capsules 4.5–7.5 mm. 2n = 76, 114, 152.
