Description
The vernacular name for Hopea polyalthioides, Giam rambai refers to drooping leaf-sprays. It is a small-sized tree (not more than 30 m) and is endemic to Peninsular Malaysia. It inhabits lowland areas of dipterocarp forests (Chua et al., 2010). The leaf undersurface is velvety soft but later becomes glabrous as it ages. The flowers are pale pink and rather small when expanded. The fruit is about 2 cm long, the nut is ovate with a sharp-pointed tip and embraced at the base by the sepals. Giam rambai is a hardwood species but it produces a small pole and has no potential value in the timber industry. Due to its restricted distribution and habitat loss, Giam rambai is categorized as Endangered (Yong et al., 2011, Yong et al., 2021).
