Calophyllum tetrapterum Miq.

Species:C. tetrapterum
Common Names:Bintangor Kuning


This is a medium-sized tree, sometimes up to 42m tall. No buttress. The bole is fawn, dark grey or yellow-brown in colour, sometimes with reddish patches. The bark is smoothed, cracked or with boat-like fissures. This can be confused with C. pulcherrimum, expect that the midrib of C. tetrapterum is clearly raised on the underside. Its apical bud are small, short and pointed and unlike that of C. pulcherrimum, is functional.  Leaf shapes can be variable, although they are usually broadly oblong, measuring 4 × 1.5 – 10 × 4 cm, with short, blunt tips. The secondary nerves are rather obvious on both surfaces. Flowers have white sepals and petals, in 4 and 4 or 2 and 0. The fruits are smaller than that of C. pulcherrimum and lack the thick outer layer and stone walls of the former.
