Pteleocarpa lamponga (Miq.) Bakh. ex K. Heyne

A medium-sized tree up to 37 m tall; bole straight, cylindrical, up to 60 cm in diameter; crown bushy, open; bark surface smooth to shallowly fissured, yellowish to greenish-grey, inner bark laminate, pale brown to pale orange. Leaves alternate, simple, obovate, entire, exstipulate. Flowers in a many-flowered, terminal, paniculoid inflorescence, 5-merous; calyx imbricate; corolla yellow or rarely red, with a short tube; stamens with sagittate anthers; ovary superior, 2-locular with 1 upright and 1 pendulous ovule in each cell, style 1, divided to the base. Fruit a 1-seeded samara, suborbicular, with a wide, radially veined wing. Seedling with epigeal germination; cotyledons narrow, ovate, leafy; hypocotyl elongated; all leaves arranged spirally. Leaves wither yellow before shedding. Pteleocarpa is sometimes placed in the small family Ehretiaceae, which has been split off from the Boraginaceae, but it is actually unclear to which family this genus belongs. If it does prove necessary to create a new family to accommodate it, that family's taxonomic position will probably remain uncertain.

The winged fruits are wind-dispersed.

Pteleocarpa occurs scattered but may be locally common in well-drained, primary or secondary, lowland and hill forest. Habitat types include mixed dipterocarp and kerangas forest.

Pteleocarpa can be propagated by seed. Seeds of P. lamponga have about 55% germination in 3-7 weeks, whereas 80% of sown fruits germinated in 4-12 weeks. Fruits should be covered with about 2 cm of soil.

Pests: When seedlings are transferred to polythene bags they prove to be susceptible to nematodes (Meloidogyne spp.) causing swollen stems, knotty roots and finally dying of roots, and to secondary virus infections. To control this pest a nematicide should be applied 2-3 weeks before planting.

Ornamental: The trees are also planted as ornamentals. Shade or shelter: The trees are also planted as a shade.

Food: The ripe seeds are boiled and eaten as a flavouring. Timber: The wood of P. lamponga has been used for house building and interior construction.
