Abstract

A species new to science of the megadiverse genus Cyrtandra (Gesneriaceae) and endemic to the limestone forest of Samar Island Natural Park, Philippines, is described. It is distinct in its hairy bracts at the base of the adaxial surface and its long pendulous umbelliform inflorescences that comprise either solitary flowers or branches carrying two clusters of 7–9 diminutive flowers. A conservation assessment following the Red List criteria of the IUCN Standards and Petitions Subcommittee is proposed, and a line drawing and photographs of the species are provided.
