    • n Rhizophora A genus of polypetalous trees, the mangroves, type of the order Rhizophoraceæ, and of the tribe Rhizophoreæ. It is characterized by a four-parted calyx, surrounded with a cupule or involucre of partly united bractlets, by its four petals and eight to twelve elongated and nearly sessile anthers, which are at first many-celled, and by a partly inferior ovary which is prolonged above into a fleshy cone and bears two pendulous ovules in each of its two cells. There are 2 (or, as some regard them. 5) species, frequent on muddy or coral shores in the tropics, there forming dense and almost impassable jungles known as mangrove-swamps. They are trees with thick cylindrical and scarred branchlets, bearing opposite thick and smooth coriaceous leaves, which are ovate or elliptical and entire. Their large rigid flowers are borne in axillary clusters, followed by a nut-like one-seeded fruit. The seed is remarkable for germinating while yet in the longpersistent fruit. It contains a large embryo with a very long club-shaped radicle, which soon pierces the point of the hard pericarp and lengthens till it reaches the mud, or becomes a foot long before falling. The mangrove is also remarkable for spreading by aërial roots. The ordinary species is R. mucronata, which reaches to semitropical Florida, the delta of the Mississippi, and Texas. See mangrove, 1.
