Morphological description
Tree 21 m high and 29 cm in diameter. Stipules lanceolate, 1.5-2 mm long, deciduous.
Leaves 1(or 2)-foliolate; petiole up to 12 mm, the apical part prolonged laterally at the base of the petiolule into a usually deciduous, short tip, petiolule up to c. 5 mm, both loosely puberulous. Leaflets chartaceous or subcoriaceous, oblong- or obovate-elliptic, 15-22 by 6-8 cm; apex rotund, or apiculate; base cuneate, symmetric; almost glabrous except sometimes sparsely puberulous often along the midrib above, loosely, minutely puberulous beneath; nerves c. 9 per side.
Inflorescences racemose, terminal, or sometimes seemingly axillary, solitary or up to 4 fasciculate, 7-12 cm long, erect, puberulous, densely flowered; bracts ovate, sometimes 3-lobed at the apical part, c. 2 mm long, puberulous outside, persistent; bracteoles at the lower part of the pedicel, very small, triangular, c. 1 mm long; pedicels c. 3 mm, articulated at the base, puberulous.
Flowers green, sparsely puberulous outside. Hypanthium c. 1 mm long, loosely puberulous inside. Calyx lobes ovate or obovate, 4-5 by 2.5-3.5 mm, glabrous inside. Stamens (8-)10; filaments 5-10 mm, glabrous; anthers c. 1 mm long; connective slightly broader than the anther cells. Pistil shortly stipitate; stipe c. 1 mm, free, slightly loosely puberulous; ovary 2-3 mm long, (3- or)4-ovuled; style 3-5 mm, hairy except glabrous at the apical part; stigma slightly thicker than the style.
Pods not seen.
Distribution
Malesia: Malay Peninsula (Pahang).
Habitat and Ecology
Alluvial valley floor. Flowering in Febuari.
Note
The species is only known from the type collection. In the original publication the leaves were described as simple (`foliis simplicibus'). However, they are distinctly either unifoliolate or 2-foliolate as examined from the isotype in Leiden.
