Description
Back to top

Mengarung (Dusun) and berangan entadu (Iban) are the local names for Castanopsis psilophylla. This tree’s bole can be around 50 cm in diameter and reach a height of 30 m. It has smooth or finely fissured brown bark. The sapwood is in yellowish or whitish colour. The branchlets are almost glabrous (smooth) from the beginning. Its ovate leaves are glabrous on both sides. Male flowers have obtuse perianth lobes and are distributed in clusters of 3 along the rachis, whilst female flowers have acute perianth lobes and are scattered singly. In each pear-shaped cupule, there are 3 to 5 asymmetrical seeds with thin wall but only one of them is well-developed. In addition, the seeds are known as edible (Soepadmo & Saw, 2000).

The distribution of Castanopsis psilophylla is within Borneo, the Philippines and Banguey Island. This species is usually found in Sabah. In Sarawak, it is only recorded from Limbang and Marudi districts. It inhabits in primary and secondary hill mixed dipterocarp forests at elevations of up to 1000 m (Soepadmo & Saw, 2000).
