An uncommon tree from the lowland forest that can grow to 27 m tall. The flowers are white. The fruit is dark purplish, 1.2 cm across and depressed globose in shape.
Previously recorded as extinct in Singapore, this species was recently re-discovered in Singapore in 2006 when keen eyed botanists at the Singapore Zoo and NParks came across this tree.
The species is naturally distributed in Peninsular Malaysia and Singapore. Syzygium is well represented in the Singapore forest and trees of the genus have similar leaf morphology. Therefore, it may take further investigation into the reproductive structures like flowers and fruits when available in order to uncover the tree species.
This rare Syzygium conglomeratum had a large girth of 2.65 m when it was endorsed as a Heritage Tree in 2020.
