Characteristics

Tree, up to 25 m, 40 cm dbh. Twigs glabrous to rather densely very shortly patently hairy. Axillary buds 2 (or 3), 1.5-2.5 mm long, shortly hairy, sometimes irregular and larger because of cork-forming in apical region. Petiole 6-11 mm, not transversely wrinkled, shortly patently hairy to glabrous; glands absent or small. Leaf-blade (5—)7—16 by (2-) 2.5-6.5 cm; above slightly bullate to flat between secondary nerves, dull, greyish green to light reddish brown, midrib glabrous to patently minutely hairy in basal half; beneath mostly rather dull, yellowish green, glabrous to minutely patently hairy, midrib slightly prominent to flat, secondary nerves 4-6 pairs, mostly forming a rather indistinct intramar-ginal nerve, venation mostly not very prominent, sometimes rather indistinct; glands (0-)4-25, often situated near midrib, 0.3-0.5(-0.7) mm diam.; basal glands often present, relatively large. Inflorescences much shorter than the leaves, un-branched; axes slightly angular, sparsely to rather densely patently shortly hairy. Pedicel (2.5-) 4-6(-10) mm, rather sparsely to densely minutely hairy. Sepals nearly glabrous outside; outer sepals 2.1-2.8 by 1.3-2.5 mm, inner sepals 2.5-4(-4.5) by 1.5-3.2 mm. Petals yellowish or white, when dry orange, the longest one 8—9(— 11.5) mm; carina sparsely to rather densely appressedly hairy outside, inside hairy to halfway or up to the apex; other petals glabrous to sparsely hairy outside, lateral petals hairy inside to halfway, upper petals hairy inside to apex. Stamens: filaments nearly free or connate over up to 1.5 mm; anthers c. 0.4 mm long. Ovary glabrous or less often rather sparsely appressedly hairy and probably soon glabrescent; style glabrous or less often sparsely appressedly hairy in basal part; ovules 4. Fruit globular, upto 1.8 cm diam., dull, wrinkled, light greenish brown; pericarp soft, thin; pedicel mostly up to 7 mm, reddish.
