ResumoInstituto de Botanica Darwinion, Casilla de Correo 22, (1642) San Isidro, Argentina. ABSTRACT: Ruellia sanguinea (Acanthaceae) and allied species in Argentina, Uruguay and southern Brazil. In this area, species allied to Ruellia sanguinea Griseb. are characterized by their narrow red corollas with small semierect lobes which suggest hummingbird pollination, their few-seeded clavate capsules, and their glabrous seeds with hairy margins. Four species are delimited, described, and illustrated, and distribution maps are given. A new combination is proposed: Ruellia brevifolia (Pohl) Ezcurra, and the names R. graecizans Backer, R. serratitheca Rusby, and R. kuntzei Lindau, are reduced to synonymy for the first time. Ruellia longipeduncu lata Lindau, known for Bolivia, is now reported for Argentina. The area of Ruellia angustiflora (Nees) Lindau ex Rambo is expanded to southern Brazil, SE Paraguay, NE Argentina and northern Uruguay, and R. sanguinea, having been erroneously confused with that species, is excluded from that area, thriving instead in southern Bolivia and NW Argentina.
