Taxonomy

The taxonomic status is pending for approval

Description

Seraya Timbau or Meranti Rambai is a large tree that may exceed 1 m in diameter. This species is endemic to Borneo. It grows in the mixed dipterocarp forests up to 400 m altitude and prefers on deep and well-drained sandy clay soils (Yong et al., 2011). In Sarawak, the fruits are a source of illipe fat (Blicher-Mathiesen, 1994). This dipterocarp species is categorized as Critically Endangered due to its threatened by rates of exploitation of major source of light red meranti timber for north-east Borneo (Ashton, 1998).
