Crudia reticulata

Author: Merrill

Morphological description (reticulata Crudia C ToS 33 )
Treelet 5-9 m high and 7-15 cm in diameter, or tree to 18 m high and 20 cm in diameter, sometimes shrub -like (1-)3-4 m high, rarely a climber (?). Stipules intrapetiolar, falcate, 5-6 mm long, caducous.

Leaves (1-)2- or 3-(4-)foliolate, shortly petioled; petiole and rachis 0.5-2(-4) cm long, prolonged beyond the upper petiolule into a subulate tip c. 5 mm; petiolules short, 3-7 mm, glabrous. Leaflets firmly chartaceous, elliptic, elliptic-, ovate- or obovate-oblong, 10-29(-36) by 3-8(-12.5) cm, apex acuminate or rather abruptly caudate-acuminate, the acumen slender, 1.5-2.5(-3.5) cm long; base cuneate, acute, obtuse, or rounded, symmetric or slightly unsymmetric; glabrous or rarely sparsely minutely hairy below; nerves 5-9 (or more) per side.

Inflorescences racemose, axillary, up to c. 10(-28) cm long, the rachis puberulous, moderately flowered; bracts subulate and long-drawn, or 3-lobed with the central lobe relobed and bristle-like, slightly hairy, up to c. 8 mm long, sometimes many, aggregate, surrounding the base of the peduncle and brush-like, (semi-)persistent, puberulous outside, slightly ciliate on the margins, those at the base of pedicels rather small, triangular, 0.3-1.5 mm long; bracteoles minute, triangular, c. 0.5 mm long; pedicels 3-5 mm, articulated at the base, puberulous.

Flowers puberulous outside, glabrous inside. Hypanthium c. 1 mm long. Calyx lobes ovate or broadly ovate, 3.5-4 by 2-2.5 mm, with 3(-5) longitudinal veins. Stamens (8-)10; filaments 4-6 mm (or longer); anthers ellipsoid, c. 0.8 mm long. Pistil stipitate; stipe free, c. 1 mm long, slightly puberulous; ovary c. 2 mm long, (3 or)4(-6)-ovuled; style 4.5-5.5(-10) mm, glabrous except slightly hairy towards the base; stigma obscure.

Pods (young) ellipsoid or ovoid 8.5-12.5 by 3-4 cm, apex shortly acuminate, not beaked, base rounded or acute, densely shortly brown hairy.

Seeds broadly ellipsoid or suborbicular, 2.6-3.3 by 2-2.4 cm, c. 1.2 cm thick, testa rusty scurfy, finely rugose.

Malesia: Borneo (Sabah, Sarawak, Kalimantan).

Habitat & Ecology
Lowland primary forest, dipterocarp forest, marshy, periodically inundated, seasonal or peat swamp, sandy soil, moderately drained ground, loam soil with coral limestone, occasionally found in secondary forest, altitude up to 96(-250) m, once recorded found at 1000 m (Berau). Flowering January- April, July-September; fruiting April, June-October

1. In Crudia reticulata the nerves on the upper surface of the leaflets are often in slightly shallow grooves, horizontal or oblique and the distal ends joining together in a series of prominent arches up to c. 10 mm from the margin. The basal bracts of the peduncle are rather long (up to c. 8 mm), sometimes many, aggregate, (semi-)persistent, surrounding the base and bush-like. This kind of bracts is very characteristic for the present species.
2. There is one collection (SAN 49887, K, L) which was recorded as a `woody climber clinging on an obah (i. e. Eugenia ) tree'.
