Low shrub or small tree, 3-12 m, 18-20 cm dbh. Twigs often sparsely appressedly hairy when young, soon glabrescent. Nodal appendages bluntly conical to triangular, up to 0.2 mm long but often smaller. Axillary buds 2-3, up to 2 mm long, sessile or the upper very shortly stipitate, acutish, often distinctly keeled, more or less densely shortly hairy. Petiole 3-5 mm, ± indistinctly transversely wrinkled, brownish, often sparsely thinly hairy when young, glabrescent. Leaf-blade 5-14 by 1.4-4(-5.5) cm, margin more or less distinctly undulate, often a little incurved, apex acutish, rarely shortly acuminate; above yellowish green to brown, midrib flat to slightly prominent in apical half, in basal half with a central groove; beneath light yellowish or brownish, papillose, midrib glaucous or sometimes sparsely appressedly hairy, secondary nerves mostly hardly distinct from finer veins, c. 8-14 pairs, not forming an intramarginal nerve; glands mostly numerous, 0.2-0.3 mm diam., but sometimes larger (up to 0.8 mm) and then of irregular form. Inflorescences mostly longer to much longer than the leaves, basally branched but sometimes seemingly unbranched if lower bracts resemble normal leaves; axes mostly distinctly flattened basally, rust-brown, more or less densely patently shortly hairy; in basal part flowers with 3-5 together, solitary in apical part. Pedicel 2-3.5 mm, ± densely patently shortly hairy. Sepals: outer sepals 1.7-2.2 by 1.5-2 mm; inner sepals 2.2-2.7 by 2-2.9 mm. Petals pinkish or white, the upper ones often with a yellow spot, when dry yellowish, the longest one 6-9 mm long; carina rather densely (woolly) hairy outside; other petals hairy at very apex. Stamens 8, rarely in some flowers 9; anthers 0.3-0.5 mm long. Ovary appressedly hairy; ovules 4.
