Characteristics

Tree 4-5 m. Twigs 1—1.5(—2) mm diameter, glabrescent, hairs shaggy, 1 mm long; older twigs neither Assuring nor flaking; lenticels not apparent. Leaves (thinly) chartaceous, (elliptic-)oblong, 6-12 by 2-4 cm, base attenuate, apex (acute-)acuminate; upper surface olivaceous or brown, lower surface yellowish brown by persistent fine felty hairs mixed with appressed stouter hairs 0.5 mm, partially late glabrescent leaving a grey undersurface; not papillose; dots absent; midrib flat above; lateral nerves 10-15 per side, at 45(-60)° to the midrib, flat and indistinct above, lines of interarching and venation indistinct on both surfaces; petiole 0.6-15 by 1-2 mm; leaf bud 8-13 by (1.5-)2-2.5 mm, hairs conspicuous, 1 mm long. Inflorescences between the leaves, axillary or to 1.5 mm supra-axillary, ± rusty pubescent, mostly to 3 mm pedunculate, almost sessile, ending in a simple or forked scar-covered brachyblast to 5 mm long; in male: with clusters of 3-5 flowers, buds of various sizes; bracts 1 mm or less, pubescent, caducous; in female (from infructescences): peduncle short, 1-3-flowered; flowers with scurfy hairs 0.1-0.4 mm. Male flowers: pedicel often ± curved, 1.5-3(-3.5) mm long, bracteole ovate, (0.5-) 1-1.5 mm long, persistent or late caducous; buds (ovoid-)oblong, 7-8 by 1.5-2 (-2.5) mm, narrowed from the middle to the apex, base broadly rounded, cleft c. 1/7, lobes membranous, 0.7-1 mm, c. 0.3 mm thick, perianth inside smooth or in the lower half finely warty-bullate. Androecium slender, 6-6.5 mm; androphore 3-4 by 0.4-0.5 mm, hairs dense, 0.5-0.8 mm; synandrium 2-3.5 by 0.5-0.6 mm, thecae 8—10(—12), sterile apex ± slender, ± acute, 0.6 mm, reaching the base of the perianth lobes. Female flowers (from perianth remnants under immature fruit, Staujfer c. s. 5552): pedicel 3 mm long; buds 6 mm, lobes 1 mm long. Fruits solitary, ellipsoid, 2.5 by 2 cm, hairs dense, rusty, scurfy, 0.2-0.4 mm, stouter (0.5 mm) towards the base and apex; pericarp 1-1.5 mm thick, seeds not seen (probably 1.5-2 cm); fruiting pedicel slender, 5 mm long.
