Characteristics

Small tree to 10 m; young branches finely pubescent. Leaves chartaceous, lanceolate or narrowly to broadly elliptic, c. 5-10 by 1.5-5 cm, base attenuate, apex long-acuminate, margin entire or remotely and finely dentate, becoming glabrous or pubescence persisting on midrib and main veins below or occasionally also on the lower surface; petiole 5-10 mm, glabrous or pubescence persistent. Monoecious. Inflorescences axillary or supra-axillary, dichasia or few-flowered pleiochasia, rachis, branches, bracts and receptacles pubescent, the rachis slender with a long peduncle below the first branches, branches opposite or subopposite, singly or in clusters. Male receptacles globose, narrowed into the pedicel, 2-2.5 mm ø; tepals 4, rounded, minute; stamens 4, 1.5 mm long, filament pilose. Female receptacles similar but larger, c. 4 mm ø at anthesis, at and near the ends of inflorescences (when present); tepals 4, minute, inner surface long-pilose, carpels numerous, c. 2.2 mm long, ovary pilose, style awl-shaped, glabrous. Fruiting receptacle slightly enlarged, leathery. Drupes ovoid, 11-14 by 9-11 mm, verrucose, sessile or shortly stipitate.

Leaves glabrous; petiole 4–6 mm long; lamina narrowly elliptic to elliptic, 4.5–14 cm long, 1.2–5.4 cm wide, cuneate to attenuate at base, entire or irregularly and sparsely toothed, acute to mostly acuminate; midrib prominent on both surfaces, flattened above, raised beneath. Male inflorescences 2–3 cm long, 3 (–5)-flowered, appressed-pubescent. Male flowers ± globose, c. 3 mm diam.; tepals as 2 pairs; stamens as 2 pairs, rarely only 1 pair; filaments 2 slightly longer, 2 slightly shorter, slightly pubescent, dark. Female inflorescences 2–3 cm long, 3-flowered, shortly pubescent. Female flowers globose to depressed-globose, c. 3 mm tall, c. 4 mm diam.; tepals as 2 pairs over ostiole; carpels 8–12, c. 2.5 mm tall; the ovary pubescent; stigma elongate, with 4 lines of pubescence.
