Guangxi province, Southern China. Over the years, we have noticed that the Bruguiera gymnorhiza species in Southern China appears to have calyxes that are deep red in colour, unlike the ones in tropical Singapore or Malaysia where the calyxes have a wide range of colour variation: from green to pink and to red.

The calyx colour of fresh propagules is very important to identify the different Bruguiera species.Over the years, we found that the best way to teach mangrove plant identification is to do the comparative approach. In this photo, Bruguiera gymnorhiza (left), is placed alongside Bruguiera sexangula (yellow), Bruguiera hainesii (pink), Bruguiera cylindrica (yellowish-green) and finally on the right, we have Bruguiera parviflora.

Previously thought to be extinct in Singapore, several trees of Bruguiera sexangula were accidentally discovered in 2002 on Pulau Tekong. Following which the propagules were collected and grown into older saplings for mangrove restoration projects in Chek Jawa (Pulau Ubin), Pasir Ris Park's mangroves, West Coast Park', and Sungei Buloh Wetlands Reserve. Recently in 2008, a new population of B. sexangula trees was discovered in Sungei Buloh Wetlands Reserve.
