Description

Tree up to 15 m tall. Branchlets 3-13 mm thick, yellowish- to whitish-puberulous and with (rather) dense, brown, pluricellular hairs. Stipules 3-12(-15) cm long, caducous, white-puberulous to -subsericeous outside, densely hairy inside; petiole (2-)4-30(-46) cm long; blade subcoriaceous to chartaceous, entire, ovate to narrowly ovate to elliptic to narrowly elliptic and (6-)10-25 x (4.5-)6-10 cm or 3-lobed to 3-fid to 5-7-fid to -parted and 13-30(-42) x 13-30(-40) cm, apex acuminate (to obtuse), base (obtuse to) truncate to cordate, upper surface scabrous to scabridulous, sometimes smooth, lower surface on the main veins yellowish-appressed-puberulous, between the tertiary veins arachnoid-tomentellous; secondary veins (5-)12-25(-40) pairs, basal pair branched. Staminate inflorescences: peduncle 2.4-4 cm long; flowers solitary to loosely glomerate at the end of the branchlets, usually sessile; perianth 1-1.5 mm long; filaments shorter than the perianth. Pistillate inflorescences usually distinctly branched; peduncle 2-4 cm long; flowers (6-)10-ca. 50; pedicel 2-5 mm long; perianth 3-4 mm long; stigma discoid. Fruiting perianth ovoid to ellipsoid, ca. 1.5 cm long, scabrous; pedicel up to 0.8 cm long.
