Stems erect or trailing; branches yellow-brown or gray-brown, (sometimes weakly glaucous), glabrous; branchlets yellow-green or yellow-brown, glabrous or puberulent. Leaves (marcescent); stipules absent; petiole 1.5-5 mm; largest medial blade usually amphistomatous, narrowly elliptic or elliptic, 9-26 × 3.8-7.5 mm, 2.4-4.3 times as long as wide, base cuneate, margins flat, entire, ciliate, apex acute, acuminate, or convex, abaxial surface glabrous or pilose, hairs wavy, adaxial slightly glossy, glabrous or pilose; proximal blade margins entire; juvenile blade glabrous or sparsely villous abaxially. Catkins: staminate (20-50 flowers), 12.5-26.5 × 5.5-9 mm, flowering branchlet 1-11 mm; pistillate moderately densely to loosely flowered, (15-35(-43) flowers), stout or subglobose, 10-23(-30 in fruit) × 5-8 mm, flowering branchlet 2-9 mm; floral bract brown, 1.6-2.6 mm, apex rounded, entire, abaxially sparsely hairy or ciliate, hairs wavy or straight. Staminate flowers: abaxial nectary (0-)0.2-0.6 mm, adaxial nectary oblong or square, 0.4-1.2 mm, nectaries distinct; filaments distinct or basally connate; anthers ellipsoid, 0.3-0.6 mm. Pistillate flowers: adaxial nectary oblong or square, 0.5-1.2 mm, longer than stipe; stipe 0-0.6 m; ovary pyriform, usually densely villous, beak abruptly tapering to or slightly bulged below styles; ovules 6-10 per ovary; styles 0.3-1 mm; stigmas slenderly cylindrical, 0.28-0.39-0.56 mm.
