Characteristics

Spreading canopy tree, 6-25 (-30) m, bole straight, up to 12 m, up to 50 cm ø, with slender and weak pneumatophores in wet places; bark grey to brown, smooth or cracked. Branchlets robust, often covered with resinous exudation as are the inflorescences. Leaves elliptic or oblong-elliptic, apex obtuse or slightly emarginate, base broadly cuneate to rounded, coriaceous, firm, shining green above, dull and greyish or yellowish green beneath, glabrous, 14-22 by 4-8(-12) cm, nerves in 20-25 pairs, straight and parallel to each other, slightly raised on both faces, reticulation dense, visibly raised above only; petiole 2-3(-4) cm by 2(-3) mm, minutely transversely wrinkled. Inflorescences axillary, solitary, with 3 or 4 secondary peduncles (1-3 cm) crosswise and umbellately spreading from top of main peduncle (2.5-4 cm by 1.5-2 mm), flowers several, close together, scorpioid, uni-or biseriate, on the upper ± recurved part of the secondary peduncles, thick-pedicelled for 0.5-2(-3) mm; bracts at base of secondary peduncles knob-like, rather obscure. Calyx obconical-cupular, maybe suddenly narrowed at base for 1-2 mm to a kind of foot for 1-2 mm, rugose, persistent and more spreading or almost patellar under the ripe fruit, 4-5 by 6-7 mm. Petals chartaceous, glabrous, veined length-wise, becoming free only in uppermost part, remaining connate for the rest, oblong, white with cream centre or greenish-yellowish, with sweet smell, (12-)13-15 by 3-4 mm. Filaments linear, fleshy, 9-10 by 1 mm, with longish white hairs below the anthers inside and at connective outside; anthers linear, thecae spreading below, 4 by 1 mm. Ovary ovoid-conical, truncate, hollow at apex, its edge folded in dry specimens, 3.5-4 by 2-2.5 mm. Drupe oblong-ellipsoid, apiculate, reddish and smooth in the lower ¾, papillate and greyish-yellowish in the upper ¼ part, 3.5-4 by 2-2.5 cm.
