Lai Chi Wo
The mangrove in Lai Chi Wo consists of Looking-glass mangrove ("Heritiera littoralis") and White-flower Derris. Looking-glass mangrove is a species of mangrove whose biggest forest is to be found in Lai Chi Wo. Every April and May are their blossom seasons and fruits can be harvested from June to October. The fruit is round and green at first, and then become brown when it ripens. In the middle of the fruit, you may find a carinate tuber which makes it look like the Japanese Ultraman. Hence, it is commonly called "Ultraman Fruit". Heritiera littoralis is grand, peculiar and has a thick tree-crown. It is almost tall enough to reach the chest of people. The interlaced plank buttress serves to grasp the swampy soil in the tide zone to hold the body of the tree. And the "natural swing" around the forest of Looking-glass mangrove in fact is formed by the growing White-flower Derris.
