Catkins: staminate 13-48 × 4-6.5(-8) mm, flowering branchlet 3-31(-50) mm; pistillate densely flowered, slender or stout, 18-56 × 4-10 mm, flowering branchlet 3-27(-40) mm; floral bract tawny, 0.8-1.6 mm, apex rounded, entire, abaxially densely hairy, hairs straight. Staminate flowers: abaxial nectary 0.6-0.8 mm, adaxial nectary narrowly oblong, 0.5-1.2 mm, nectaries connate and shallowly cup-shaped, or distinct; filaments distinct, hairy on proximal 1/2; anthers ellipsoid or globose, 0.3-0.5 mm. Pistillate flowers: abaxial nectary (0-)0.8-0.9 mm, adaxial nectary oblong, ovate, or narrowly oblong to almost filiform, 0.7-1.4 mm, shorter to longer than stipe, nectaries distinct or connate and cup-shaped; stipe 0.4-1.2 mm; ovary pyriform or obnapiform, densely short-silky, hairs cylindrical, beak abruptly tapering to styles; ovules 13-15 per ovary; styles connate 1/2 their lengths to almost distinct, 0.2-0.4 mm; stigmas flat, abaxially non-papillate with rounded tip, slenderly cylindrical, or 2 plump lobes, 0.2-0.28-0.36 mm.
