Mangrove
Mangrove, the name of a group of trees mostly belonging to a small dicotyledonous order, the Rhizophoraceas, but applied also to the white mangroves (Avicennia), which belong to the verbena family. Mangroves grow on estuaries, salt marshes, and muddy shores along the coasts of both hemispheres within the tropics, flourishing in salt water, sending down numerous adventitious rootlets from their branches to the mud, and even tap-roots, from the seeds in the fruit still on the trees. Some have hard durable wood, and the bark is used in tanning. The common mangrove is Rhizophora Mangle.
