Abstract

A revision of Begonia sect. Symbegonia, endemic to New Guinea, is presented, with descriptions of five new species (B. arauensis M.Hughes, B. asaroensis J.Gagul, B. erodiifolia Sands, B. mimikaensis Sands and B. vinkii Sands). There are 18 species now recognised, and a key is provided for their identification. Ten of the species are assessed to belong to the IUCN category Data Deficient, and eight to Least Concern.
