Rhizophora is a genus of tropical mangrove trees, sometimes collectively called true mangroves. The most notable species is the Red Mangrove (Rhizophora mangle) but some other species and a few natural hybrids are known. Rhizophora species generally live in intertidal zones which are indundated daily by the ocean. They exhibit a number of adaptations to this environment, including stilt-roots that elevate the plants above the water and allow them to respire oxygen even while their lower roots are submerged, and a cytological molecular "pump" mechanism that allows them to remove excess salts from their cells. The generic name is derived from the Greek words ριζα (rhiza), meaning "root," and φορος (phoros), meaning "bearing," referring to the stilt-roots.
The beetle Poecilips fallax is a common pest of these trees.
The Red Mangrove is the state tree of Delta Amacuro in Venezuela; a dark brown dye can be produced from it, which is used in Tongan ngatu cloth production.
