Many-petaled Mangrove reproduces by vivipary. The propagules are considerably thicker than those of Kandelia obovata and Aegiceras corniculatum, and they look like cigars hanging on trees. The plant tissue contains a high content of tannin, which tints the plant red. Many-petaled Mangrove is easily distinguishable from other mangrove species because of its large leaves and the red calyx of its flowers.
