Smith et al. (1986) recorded 20 species of Begonia from Sulawesi. In the last decade, intensive study of Sulawesi Begonia has revealed many new species, with the total of native species increasing to 42 (Hughes, 2006; Thomas, et al., 2009a, b; Gir-mansyah, et al., 2009).     In 1998, during a trip to Tanah Toraja, South Su-lawesi the author found several identifiable species, including Begonia aptera, B. hirtella, B. longifolia and B. siccacaudata. Among the collections from Rantepao is a new species which we named Begon-ia hooveriana Wiriad. in honor of Mr Walter Scott Hoover from New England Tropical Conservatory, USA who sponsored the expedition to look for new species of Begonia in Indonesia.

South Sulawesi, endemic.  Habitat. This species can be found from lowland to hilly areas up to altitudes of about 900 m asl, waste places and open area.  Notes. The new species is characterized by its flat shining dark green leaves that make this species is an attractive plant. Unlike any other Begonia in Su-lawesi, the Begonia hooveriana is very distinct. The stem erect then arching down. Stipules in pairs, oblong with needle tip, thick, glossy green. Leaf has very long stalk, leaf blade glossy or shining  at the upper surface.
