Rivina (ri-vi'nä), n. [NL. (Plumier, 1703), named after A. Q. Rivinus: see Rivinian.] Agenus of apetalous plants of the order Phytol acc a ceæ, the pokeweed family, type of the tribe Rivi It is characterized by a globose and compre ed nex. fleshy fruit, and by flowers with 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. læris, 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 or 8 feet high, or in some forms much smaller, producing many two-forked and two-fur rowed 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.
