Description:
Species Description - Glabrous, Subscandent shrub, treelet, or tree 3-10(-16) m tall; trunk to 15 cm diam.; bark rugulose, greenish to grayish. Branchlets finely striate, subterete. Leaves ovate to elliptic or oblong, sometimes broadly so, apex more or less abruptly acuminate for 0.5-1.5 cm, tip blunt, base cuneate to the petiole, thin-chartaceous to subcoriaceous, rarely firmly so, shiny or dull, remaining usually green in the dry state and subdensely wrinkled and/or tuberculate on both surfaces, the latic-ifers not or not much visible in general, edge a little revolute, (4-, 6-) 10-18(-25) x 3-5(-6, -9) cm, midrib slightly prominent above, more distinctly so beneath, lateral nerves 6-9 pairs arcuately ascending and rather distinctly looping before the edge, usually slightly impressed above, raised beneath as are a number of shorter nerves between, reticulation of veins and veinlets rather dense, distinct to subinconspicuous; petiole 5-10(-15) mm long. Flowers (1-)3-6 in a fascicle per foliate or defoliate axil, arising from a small cushion formed by numerous thin small bracts; pedicels 1-2 mm long. Calyx patently cup-shaped, shortly 5(-6)-dentate, green, ca. 1 mm high, 2 mm diam. Petals 5(-6), ovate-lanceolate, coherent below, sometimes so to the middle, white, densely hispidulous-hairy inside, 4-5(-6) mm long, 1.5(-2) mm broad at base. Stamens 10(-12); filaments slender, 1 mm; anthers subglobose, 0.4 mm. Ovary depressedly globose, 10-sulcate; style thickish, short. Drupe ellipsoid-oblongoid, sometimes subobovoid, apex mucronulate by the remaining style-base, first green, then pale yellow to orange at maturity, 10-11 (-14) x 6-8 mm, the subtending fruit-calyx becoming thickish, but only slightly accrescent, including only the base of the drupe, greenish to dull red, 2-3(-5, -7) mm diam., 1.5-2(-3) mm high; peduncle stoutish, 1.5-4 mm long; pericarp thin, brittle, smooth or a little wrinkled in the dry state.
