Rediscovery of the genus Tsingya Capuron (Sapindaceae) and its phylogenetic position

A recent intensive inventory in the Beanka region in western Madagascar has led to the rediscovery of a poorly known endemic and monotypic Malagasy genus: Tsingya Capuron (Sapindaceae). Tsingya bemarana Capuron was only known from the type collected in 1952 in the Bemaraha eroded limestone massif. This rediscovery allows to confirm its generic validity by providing a full taxonomical description of its only species, including its fruit so far unknown, and inferring its phylogenetic position, and to assess its conservation status.
