The largest of the three mangrove species, growing along the water edge with high stilt roots ( all mangroves have stiltroots). The most common mangrove in Liberia. See also PROTA database.All mangrove species have high and thin stilt roots; the leaves are ±similar, simple opposite, leathery, elliptic/oblong.. The terminal buds are covered by long, pointed stipules that leaf a circular scar when shed. The leaves are clustered a the end of the twigs, in whorls of 3..The distinction between species is mainly through the inflorescences and the germinating fruits on the tree; the three species occupy different habitats. The largest of the three mangrove species is R. racemosa, growing along the water edge between low and high water. lines No or only a few corky warts on the lower leaf surface.The inflorescence is much-branched, with many flowers; the germinating seed reaches 30 – 60 cm while still on the tree. The most common mangrove in Liberia. See also PROTA database. The other two Mangrove species are: R. harrissonii; smaller mangrove species, growing above the high water mark; shrub or small tree growing on the swampy and muddy flatlands bordering estuaries. Much-branched inflorescence with many flowers; germinating seed reaches 30 cm while still on the tree. Lower leaf surface glabrous or with a few scattered warts. R. mangle; small mangrove on the inner edge of the mangrove zone, with corky warts on lower blade surface; its presence in Liberia still to be documented. Inflorescence little-branched with only 2 – 4 flowers; germinating seed to 30 cm while still on the tree.
