Distribution
From Burma and southern China towards Peninsular Malaysia, Sumatra, Borneo and Palawan (the Philippines); the presence in southern India is probably due to an introduction.
Uses
The timber is used as derum if trees of sufficient size can be found. Sometimes grown as an ornamental.
Observations
- A small to medium-sized, deciduous tree of up to 33 m tall, bole often of poor shape, sometimes fluted at the base, up to 55 cm in diameter, bark surface smooth, peeling off in angular pieces or long strips with age, light brown to yellowish-brown, inner bark light green to greenish-yellow.
- Leaves elliptical to ovate-lanceolate or lanceolate, 3-10.5 cm × 1-4 cm, with an obtuse to acutely acuminate apex, glaucous beneath.
- Inflorescence consisting of small 1-5-flowered terminal or axillary cymes; flowers heterodistylous, petals dark red to pink or orange, without a nectary scale.
- Seeds (5-)6-8 per locule, unilaterally winged.
C. cochinchinense is locally common in both primary and secondary forest, as well as in open woodland and grassland. It is often found along water courses and sometimes in peat swamps up to 750 m altitude (up to 1200 m in China). The correctness of the inclusion of C. ligustrinum (Spach) Blume in the present taxon is sometimes questioned. The density of the wood is 790-1000 kg/m3 at 15% moisture content.
