Abstract

Within the Pantabangan–Carranglan Watershed Forest Reserve in Nueva Ecija, a small population of an inconspicuous Begonia was encountered. After thorough investigation, it is described here as a new Philippine Begonia species in sect. Petermannia. The new species, Begonia naemma Y.P.Ang, Aumentado & Magtoto, is distinguished from the allied species B. polyclada C.I Peng, C.W.Lin & Rubite by its larger leaves, leaf adaxially sparsely hirsute between the veins, more numerous stamens, and larger ovary wings that are ovate to oblong. Based on IUCN criteria, Begonia naemma is designated as Endangered (EN). A comprehensive description and illustration of Begonia naemma are provided.
