Four New Species of Hiraea (Malpighiaceae) and Review of H. brachyptera

Abstract

Four new species of Hiraea Jacq. (Malpighiaceae) from Costa Rica and Panama are proposed: H. hispida C. E. Anderson, H. oligantha C. E. Anderson, H. pleiantha C. E. Anderson, and H. velutinissima C. E. Anderson. A previously misidentified specimen from Panama is the first record of H. brachyptera Triana & Planch. in Central America. All species are described and illustrated. A key to species of Hiraea with multiflowered umbels occurring in Mesoamerica is provided.
