Description

Shorea singkawang is a large tree species native to Thailand, Peninsular Malaysia and East Sumatera, Indonesia, where it grows in lowland and hill dipterocarp forests (Whitmore, 1984). It is a member of the Dipterocarpaceae family, which includes many other important timber species found throughout tropical regions of the world. Locally, it is known as meranti sengkawang merah. The tree can reach up to 50 meters in height (Ashton, 1992) and has a straight, cylindrical bole with smooth, gray bark (Whitmore, 1984). The leaves of Shorea singkawang are oblong to lanceolate in shape and have drying reddish to purplish-brown colour (Ashton, 1992). The leaves are arranged alternately on the branches and are typically about 15-20 cm long (Whitmore, 1984). In Peninsular Malaysia, this species' habitat includes lowland dipterocarp forests as well as moist soil close to streams, frequently on well-drained, undulating land up to 400 m height.

The flowers of Shorea singkawang are small and greenish-yellow in colour (Ashton, 1992). They are arranged in clusters on the tree and have a strong, pleasant aroma (Whitmore, 1984). The flowers are an important source of nectar for a variety of insects, including bees, butterflies, and moths (Ashton, 1992). The tree also produces fruit with rudimentary wings (Wyatt-Smith & Kochummen, 1999).
