The buttonwood mangrove is found along the coast, but in dryer conditions than the red mangrove. Take a look at those red button-shaped flowers. You can easily remember the name of this tree because of these flowers which are shaped like old-time buttons. The leaves are semi succulent, green and have two red notches located at the base.
The soil where the plant grows is very salty, because the plant grows near the coast. Somehow the plant must find a way to get rid of the extra salt it intakes; otherwise, it will die. So how does the plant survive these salty conditions? Salt is ejected through the two red notches located at the base of the leaf. When it rains, the salt is washed away from the plant and the process just continues as long as the tree is living and healthy.
