Characteristics

Small trees up to c. 15 m. Twigs glabrous, bud scales up to 13 by 11 mm, dark and hard. Leaves oblong to elliptic, 8.5-13.5 by 3.5-5.5 cm, base acute to rounded, margin finely crenate to serrate, entire only at extreme base, apex acute, sometimes acuminate, with up to 14 pairs of secondary nerves, often not distinguishable from stronger tertiary nerves, venation widely reticulate, not prominent, with few hairs on both surfaces when very young, quite glabrous when mature. Petiole 2-3 cm long. Stipules awn-shaped, 4.5-5.5 by 1 mm, with ex-centric midrib, early caducous. Inflorescence corymbose to semi-globular in shape, up to c. 8 cm long, with up to 12 first order laterals, these up to 9 cm long and branched again, the lowermost ones in axils of leaves, rachises including the 2.5-4 mm long pedicels glabrous or faintly hairy. Flowers 5-merous, rarely 4-merous. Hypanthium obconoid, 1.5-2 mm high, upper half free from the ovary, glabrous outside. Sepals broadly triangular, 1-1.2 by 1.2-1.8 mm. Petals suborbicular to broadly ovate, 3-4.5 by 3-3.5 mm, white. Stamens 16-20, filaments up to 3 mm, glabrous, anthers 0.5-0.8 mm long. Ovary hairy on the free top, 2-, rarely 3-celled, styles up to 2.5 mm long, free. Fruits subglobular to obovoid with flattened apex, up to c. 5.5 by 6 mm when dry, upper part of hypanthium and sepals closely appressed against top of fruit, exocarp red (to purple?), mesocarp fleshy, endocarp rather hard. Seeds 2-4(-6), ellipsoid, c. 3 mm long, with firm, brown testa, endosperm a thin layer, cotyledons rather flat.
