Interesting Facts:

The Sea Apple is a coastal forest tree which can also be commonly found in young inland secondary forests in Singapore. It was first cultivated extensively as a wayside tree in the 1882 (Rao & Wee, 1989). They act as a fire screens (since they are resistance to burning) from the once lalang-rich grasslands that caught fire easily. At 2009, it is the 4th most abundant roadside tree in Singapore; numbering up to 18,106 individuals (Tan et al., 2009).

The flowers are visited by bees in the day, and bats at night; evident from a tree whereby its crown was facing my kitchen window before it was chopped down. The fruits are said to be bat-dispersed too (Rao & Wee, 1989).
