Juss. (Malpighiaceae) is a genus of vines and shrubs character- ized by distinctive, heart-shaped stipules; flowers with large, yellow, often fringed petals; and samaras with an elongate dorsal wing and two lateral winglets (Anderson 1982). Its range extends over much of Brazil south of the Amazon region and into adjacent Bolivia and Paraguay. The inflorescence units are 4-flowered umbels, which are usually arranged in compound dichasia or thyrses. In some species the secondary and tertiary inflorescence axes are suppressed at more distal nodes, such that the umbel is sessile in the leaf axil; the terminal node then bears 3 umbels and thus is 12-flowered. Recent collecting activity in eastern Paraguay yielded an additional species, here described, in which the inflorescence is so modified. The genus now comprises 29 species. Much of the range of Peixotoa is still only poorly known floristically, and more undescribed species may yet be discovered.Read More
