Khaya nyasica is native to Tropical Africa and was introduced to Singapore in the late 1970s. It produces small, white, sweet-scented flowers which then give way to tennis-ball size fruits. These fruits spilt open when ripe to release many flat brown winged seeds. The surrounding area used to be a Malay settlement in the early 19th century which grew coconut plantations in the mid-1850s before cultivating lemongrass, hence the name Geylang Serai (serai = lemongrass). The Geylang police post used to be situated here in the 1970s, before it was converted into a green space where these trees were planted. Khaya nyasica trees are now uncommon in our landscape, and this cluster of four Heritage Trees serve as a reminder of our past floral heritage. This Heritage Tree had a girth of 2.2m when measured in Year 2001.
