Description and Ethnobotany

Growth Form It is a tree, up to 40 m tall, with mall thin buttresses and stilt roots. The trunk can reach up to 0.7 m in girth. The bark is smooth and can become scaly.
Foliage Leaves are ovate, measuring 5 – 8 cm long and 2.2 – 4.5 cm wide, and have a thinly leathery texture. The leaves are green when fresh, and turning brown before falling off. Each leaf has 8 – 11 (– 13) pairs of lateral veins. The leaf tip is long (caudate), up to 1.5 cm long, while the leaf base is wedged shaped (cuneate). Domatia are absent. The leaf stalk (petiole) is 1.2 – 1.7 cm long. Stipule is linear-laneolate, measuring 1 – 1.5 mm long and 0.25 – 0.8 mm wide.
Flowers Flowers occur in a cluster (panicle) at the axis or terminal end (rarely) of the branches. Each inflorescence is up to 4 cm long and bearing up to 5 flowers. Flowers are small and cream coloured. Each flower has 15 stamens in whorls and round anthers. The connectival appendage about the same length as the anther. The ovary is ovoid and glabrous.
Fruit The fruit is winged and dry. They are borne on stalks which are 2 mm long. Each fruit comprises of two wing-like calyx lobes, measuring up to 6 cm long and 1.4 cm wide, three shorter lobes (up to 0.9 cm long and 0.7 cm wide) and one oval-shaped nut (up to 0.8 cm long and 0.7 cm wide) with a short style remnant at the tip (about 0.2 mm long).
Habitat It is found in rainforest, up to 400 m.
Associated Fauna Flowers are pollinated by insects.
Cultivation It can be propagated by seed.
Etymology The genus Hopea commemorates John Hope (1725-1768), the first Regius Keeper of the Royal Botanic Garden, Edinburgh. The specific epithet latifolia, in Latin, means broad leaves.
Ethnobotanical Uses Timber & Products: It produces merawan timber that is prized regionally for construction, such as joists, beams, house construction, door and window frames, ship building, plywood and veneer. The tree produces clear resin (dammar) which is sometimes traditionally used by local people for torches, varnish, caulking boats and applied externally to heal sores and wounds.
