Morphological description (tenuipes Crudia C ToS 33 )
Tree to 27 m high and 38 cm in diameter; buttresses steep, 1.5 m high and 30 cm extending outwards from the base. Stipules intrapetiolar, minute, c. 1 mm long, caducous.
Leaves 2-4-foliolate, shortly petioled; petiole and rachis 1.5-7 cm long, not prolonged beyond the upper petiolule; petiolules short, c. 5 mm, glabrous. Leaflets firmly chartaceous, elliptic- or ovate-oblong, 7-20 by 3-7 cm, the lower ones usually smaller; apex acuminate or rather abruptly acuminate; base cuneate, acute, obtuse, or rounded, symmetric or slightly asymmetric; glabrous; nerves 5-7 per side.
Inflorescences racemose, axillary, up to 24 cm long, glabrous, loosely flowered; bracts triangular, up to c. 1.5 mm long, glabrous, caducous; bracteoles spaciously alternate at the lower half, or subopposite or opposite at the base, of the pedicel, triangular, minute, c. 0.2 mm long, glabrous, caducous; pedicels (7-)15-22(-30) mm, articulated at the base, glabrous.
Flowers greenish white, greenish yellow, or white, scented, glabrous outside. Hypanthium c. 2 mm long. Calyx lobes elliptic or ovate-oblong, 4-4.5 by 2-2.5 mm, the inner surface often puberulous on the longitudinal, central part, glabrescent, sometimes almost glabrous on some of the flowers. Stamens (8-)10; filaments up to c. 12 mm, glabrous; anthers 0.7-1 mm long. Pistil stipitate; stipe free, c. 1.5 mm long, glabrous; ovary c. 3 mm long, (2-)4(or 5)-ovuled; style up to c. 14 mm, glabrous except often hairy towards the base; stigma obscure, slightly thicker than the style.
Pods ellipsoid or fusiform, 5-8 by 2.5-3.5 cm, swollen, 1.8-2.5 cm thick, gradually narrowed from the middle towards both ends, or beaked at apex and obtuse at base, shortly brown hairy, valves 2, coriaceous, hard, 1- or 2(or more)-seeded.
Seeds transverse-oblong or slightly reniform, 2-2.2 by 3-3.7(-4.7) cm, slightly swollen, 1.8-2.3 cm, thick, smooth, shining.
Distribution
Malesia : Borneo (Sabah, Sarawak, Kalimantan).
Habitat & Ecology
Widespread in forests; sometimes found on limestone, coral limestone rock, sandy yellow loam. Up to 540 m altitude Flowering in Febuari-May, October, November; fruiting in April, May, July-September, December.
Note
Crudia tenuipes is characterized by the following characters:
l) Leaves 2-4-foliolate with glabrous leaflets,
2) pedicels rather long, usually 15-22 mm,
3) calyx lobes often puberulous on the inner surface, glabrescent, and
4) pods ellipsoid or fusiform, swollen, 5-8 by 2.5-3.5 by 1.8-2.5 cm, sometimes remains of calyx lobes which are sparsely hairy on the inner surface can be observed with a handlens of 10X.
