Abstract

A new species of Begonia sect. Baryandra, B. sebodensis, from Zamboanga del Norte, southwestern Philippines is described and illustrated. Begonia sebodensis is morphologically similar to B. anisoptera in obliquely ovate to widely ovate leaves, four-tepaled staminate and pistillate flowers and three locular ovary but differs in glabrescent stipules, sericeous petioles, leaf margins distantly serrate and ciliate, many-flowered inflorescences, capsule wings subequal and flat. Following IUCN criteria, we propose B. sebodensis as Endangered (EN).
