Ellipanthus conduplicatus, a New Endemic Species of Connaraceae from Madagascar

Abstract

Ellipanthus conduplicatus T. Scott, Lowry & Randrian. (Connaraceae) is described as a new species from low- to mid-elevation humid forests in eastern Madagascar. It is distinguished from the two other species recognized on the island by leaf features, including the shape, size, and conduplicate nature of the blade (especially in pressed material) as well as the form of the apex, and by inflorescence length. The members of the genus on Madagascar also exhibit distinct geographic distributions. A description, illustration, photographs, and identification key are provided, along with a distribution map. A preliminary risk of extinction assessment following the IUCN Red List Criteria indicates a status of “Least Concern.”
