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.
