Description
Back to top

Dipterocarpus acutangulus, commonly known as Keruing merkah in Sabah, or Keruing beludu in Sarawak, is an emergent tree that can reach up to 60 m tall. The leaves are coriaceous with drying yellowish-brown colour. This species is commonly found in Sabah and Sarawak but rare in Peninsular Malaysia. It is also locally common in mixed dipterocarp forest on yellow sandy and sandy clay soils, at altitudes below 400 m (Soepadmo et al., 2004). This tree is used for timber and its wood types (medium hardwood) are used to produce furniture, flooring and construction (Meier, 2015).
