    • n rivina A genus of apetalous plants of the order Phytolacca-ceæ, the pokeweed family, type of the tribe Rivineæ. It is characterized by a globose and compressed fleshy fruit, and by flowers with a calyx of four small equal segments, four stamens, a short curved style, and capitate stigma. The five enumerated species are reducible perhaps to one, R. lævis, a native of tropical and subtropical America, extending into Texas and Florida, introduced in Asia and some African islands. It is an erect smooth or hairy herb with shrubby base, 6 or8 feet high, or in some forms much smaller, producing many two-forked and two-furrowed branches. It bears alternate slender-petioled thin ovate leaves, and slender pendulous racemes of small reddish-white flowers, followed by red pea-like berries. In the West Indies it is called hoop-withe. The smaller variety, humilis, is known as blood-berry, also as rouge-berry or rouge-plant, from a use made of its fruit before it becomes dry. Both plants, especially the latter, are somewhat cultivated for ornament.
