Characteristics

An evergreen shrub or a small tree up to 8 m by 10 cm ø. Branchlets puberulous when young, glabrescent. Leaves chartaceous, nerves and veins on both surfaces usually covered with appressed hairs, sometimes the upper surfaces glabrescent; ovate-oblong, lanceolate, or sometimes ovate, 6½-23 by 2.5-9 cm; base obtuse or rounded, sometimes slightly cordate; apex acuminate (acumen up to 1.5 cm); margin glandulose-serrulate, or-crenulate, the upper part of the teeth callose, usually black, sometimes yellowish, blunt; petiole 7-15 mm. Inflorescences usually 1-2 cm long, sometimes even shorter, rarely up to 5 cm, sometimes branched almost near the base; peduncle very short, sometimes up to 2 cm. Bracts small, c. 2 mm long. Pedicels short, 0.5-1.5(-2.5) mm. Flowers white, or light greenish, small, c. 3 mm ø. Calyx lobes 5, deltoid, 0.5-2/3 mm long, sparsely puberulous on both surfaces, sometimes only on the inside especially towards the upper part. Petals 5, triangular, or ovate, 0.5-1.25 by 2/3-1 mm, sparsely puberulous on both surfaces, sometimes only puberulous on the margins. Disk shallow cupular, c. 1.5 mm ø. Stamens c. 2/3 mm long; filaments much longer than the disk. Pistil slightly united with the disk at the base, conical, c. 0.5 mm long, narrowed into a short style; stigma obscurely 2-lobed. Fruits globose or subglobose, 2½-3¼ mm, reddish black, 3-4-seeded, glabrous. Seeds subglobose, or slightly obovate, 1.5-2 mm long, sometimes cuneate at the base, foveolate-rugulose or tuberculate.
