Tropical plants, there are one genus and two species in Taiwan. In the north, you can see the chessboard-foot tree, and the south is the chessboard-foot tree. The growth pattern of flowers is slightly different from that of fruit. The leaves are alternate, clustered at the top, and the leaves can reach 30-40 cm. Inflorescences emerge from the top as racemes, and some also grow from branches.

Distribution：

It is a common plant in tropical Asia, Africa, Australia and Pacific islands, the coasts of Yilan, Keelung and Jinshan in northern Taiwan and the Hengchun Peninsula in the south.
