Tree, up to 35 m, 40 cm dbh. Twigs (sometimes?) all curved downwards, pendent. Nodal glands often indistinct. Petiole 1.5-3 mm. Leaf-blade 2.6-7.5 by 0.7-2.6 cm, apex acuminate to cuspidate; above brown to olive-green, midrib sunken; beneath olive-greenish brown, papillose, secondary nerves c. 10 pairs, little more distinct than finer nerves, forming an indistinct intramarginal nerve; glands more than 10, in a row between margin and midrib, c. 0.1 mm diam. Inflorescences 2-5-flowered; axes hardly thicker than pedicel, glabrous. Pedicel c. 7 mm, glabrous. Sepals minutely ciliate, further glabrous; outer sepals c. 3.5 by 3.5 mm; inner sepals c. 4 by 4.5 mm. Petals unequal, white, when dry orange-brown, faintly ciliate, the longest one 15-16 mm; carina un-guiculate, boat-shaped, ciliate only at base; lateral petals narrowly boat-shaped; upper petals more or less straight, with cup-shaped apex. Stamens: filaments c. 0.5 mm connate, rather densely shortly hairy in basal part; anthers c. 1 mm long, glabrous. Ovary shortly stipitate, orange-brown, glabrous; style glabrous; ovules 18. Fruit pear-shaped (to broadly ovoid?), up to 4 cm diam., strongly wrinkled when dry, shiny, brown; pericarp probably very fleshy; pedicel 12-15 mm, blackish, shiny. Seeds more than 10, flattened-ovoid, c. 1 cm long; albumen nearly absent from lateral sides of cotyledons, at the broad side of these forming a layer equal in thickness to each cotyledon; embryo elliptic in side view, trans-versally flattened, cordate at base; cotyledons thickened; plumule not differentiated; radicle slightly ex-serted.
