Shrubs, 0.3-1.5 m. Stems: branches red-brown, not or weakly glaucous, glabrous or villous in patches; branchlets red-brown or violet, moderately densely and coarsely villous, (bud-scale oily). Leaves: stipules (sometimes marcescent), foliaceous, (resinous, 1.5-7.5 mm), apex acute; petiole shallowly grooved, or convex to flat adaxially, 4-15 mm, villous or puberulent adaxially, (weakly ventricose around floral buds); largest medial blade narrowly to broadly elliptic, oblanceolate, or obovate, 35-95 × 10-29 mm, 2.2-4.2(-5) times as long as wide, base usually convex, rounded, or cuneate, sometimes cordate, margins flat, entire, apex acute, convex, or acuminate, abaxial surface not glaucous, moderately to very densely long-silky tomentose to glabrescent, hairs wavy, adaxial slightly glossy, sparsely villous or pubescent to glabrescent; proximal blade margins entire; juvenile blade color sometimes obscured by hairs, very densely long-silky abaxially, hairs white. Catkins flowering before leaves emerge; staminate stout or subglobose, 20-57 × 13-18 mm, flowering branchlet 0-2 mm; pistillate densely flowered, slender to stout, 28-92(-105 in fruit) × 12-19 mm, flowering branchlet 0-5 mm; floral bract brown or black, 2.8-5.2 mm, apex acute to convex, abaxially hairy, hairs straight. Staminate flowers: adaxial nectary narrowly oblong to oblong, 0.4-1.8 mm; filaments distinct; anthers yellow or purple turning yellow, ellipsoid or shortly cylindrical, 0.4-0.6 mm. Pistillate flowers: adaxial nectary narrowly oblong to oblong, 0.6-1.3 mm; stipe 0.2-0.6 mm; ovary pyriform, (hairs refractive), beak gradually tapering to styles; ovules 16-21 per ovary; styles 0.6-1.8 mm; stigmas 0.28-0.47-0.64 mm.
