Morphological description
Tree 10.5- 20 m high. Stipules intrapetiolar, c. 3 mm long.
Leaves (2 or)3-or 4-foliolate, shortly petioled; petiole and rachis (1.5-)3-5(-9) cm long, glabrous; petiolules short, 2-5 mm, glabrous. Leaflets chartaceous or subcoriaceous, elliptic, elliptic-lanceolate, ovate- or obovate-elliptic, 6-14.5 by 3-4.5 cm, the lower ones usually smaller; apex acuminate or caudate; base obtuse or cuneate, more or less symmetric; glabrous, sometimes sparsely puberulous usually on the midrib beneath when young; nerves 6-10 per side (lanceolata Crudia lf/infl FT23).
Inflorescences terminal or axillary, solitary or rarely 2 in an axil, pendulous, up to 22 cm long, puberulous, rather loosely flowered; bracts up to c. 3 mm long, some of them 3-lobed and the middle lobe pinnately relobed with 1 terminal and 2 pairs of side lobelets; bracteoles minute, triangular, c. 0.3 mm long; pedicels 2-6 mm, articulated at the base, sparsely puberulous.
Flowers easily falling off, sparsely puberulous, glabrescent, or almost glabrous outside. Hypanthium c. 1 mm long, glabrous inside. Calyx lobes unequal, broadly ovate or suborbiculate, 3-4 by 2.5-3 mm, glabrous inside. Stamens 10; filaments (observed from flower buds or young flowers) 2-5 mm, glabrous; anthers c. 1 mm long. Pistil shortly stipitate; stipe c. 1 mm long, free, glabrous; ovary c. 2 mm long, 4(or 5)-ovuled; style c. 3 mm, glabrous; stigma obscure, slightly thicker than the style.
Pods broadly elliptic, 6 by 4-4.5 cm, with a short beak c. 7 mm long, brownish hairy, 1(or 2)-seeded.
Seeds suborbiculate, c. 2.5 cm across.
Distribution
Thailand (Peninsula); in Malesia : Malaya (Langkawi I., Selangor, Johore).
Habitat & Ecology
In forest, ridge top and hillside, up to 150(-400) m altitude Flowerin from March-December; fruiting from Febuari-November.
Note
The type of Crudia lanceolata Ridley was collected by Mohamed Haniff (or Aniff) from Langkawi and was cited in the protologue without the collector's number. Ding Hou (1996: 585) examined the type in K, which is numbered '15539 ' in Ridley's handwriting, and which was previously named and reported by him (1911) as Crudia curtisii Prain. This rather high collection number is treated here as belonging to (Herb.) Ridley or his series.
