Characteristics

Treelet or tree, (2.5-)6-15(-20) m, bole up to 10 m and 20 cm Ø; bark smooth, brownish-grey, shallowly lengthwise fissured. Branchlets with pustules on older parts. Leaves variable in shape and size, oblong to subobovate-oblong, sometimes obovate, short-acuminate or obtusely apiculate, rarely rounded, base cuneate, subcoriaceous to coriaceous, smooth, i.e. practically not tubercled, a little shining above, dull beneath both in the fresh and dry state, (6-)8-12.5(-14) by (2-)2.5-4 (rarely-7) cm, nerves c. 15 pairs, with other shorter ones between, rather straight and sub-parallel, very slightly prominent on both faces, or not rarely almost obscure beneath, similar to those of S. secundiflorus var. secundiflorus, re-ticulation of veins faintly visible above only, or obscure at all; petiole 1-1.5(-1.8) cm by (1-)1.5-2 (rarely-2.5) mm. Peduncle of the umbel-like inflorescence generally rather slender (1 mm, rarely up to 2 mm Ø), 1-2 cm long, with 3-5 branchlets of the umbel (2-)3-10 mm long, each bearing (3-)4-6 flowers crowded at the very end, the flowers seemingly on top of the peduncle when the branches of the umbel are very short; bracts at the base of the umbel ovate-oblong or broadly linear, obtuse, persisting during anthesis only, c. 2 by 2 mm. Calyx cup-shaped, c. 2 mm, rather deeply and obtusely lobed. Petals (2.5-)3(-4) mm, white-yellowish to dull pink, fragrant. Disk cup-shaped. Drupe subovoid-oblongoid, attenuate and sometimes a little curved distally, 4.5-5 by (1-)1.5-2.2 cm, pink or pale brown below, merging into pale green in the upper part.
