Interesting Facts:
This attractive and commonly cultivated tree was first introduced around the 1938 near the former Bukit Panjang village (Wee & Corlett, 1986). It bears imparipinnate leaves which are distinctly glossy. The seed pods become brown upon maturity and splits to reveal two or three large, brown, and hard seeds. Wild individuals of Callerya atropurpurea have been observed in the Bukit Timah Nature Reserve (LaFrankie et al., 2005), Central Catchment Nature Reserve (MacRitchie Reservoir area; pers. obs.), and Botanic Gardens' Jungle (Turner et al., 1996).
