This tree, called in po daeng Thai, has clustered leaves and its fruits consists of large, reddish-orange seedpods. It is known by a variety of common names, including Wild Almond Tree and Java Olive Tree.

It is similar and related to the Sterculia pexa, known in Thai as po khao, but the latter is smaller and has smaller fruits (fig.).

The seedpods often grow in star-shaped clusters and usually hold about 10-12 seeds each. When ripe, they will burst open and slowly change colour to brownish-orange (fig.).
