Habitat & Ecology

  • This is a rainforest floor species, often growing at the sides of streams, reported from between c.1700 and 2900 m above sea level.


  • Proposed IUCN category: VU D2. The Lompobatang massif is densely populated, and the forests below 1700 m are heavily disturbed. Although the distribution of this species is in the 2000-3000 m range, and hence within a protected area, given pressures on forests in this region this species must be considered as vulnerable. (Hughes, M. An annotated checklist of Southeast Asian Begonia. 2008)


Asia-Tropical:, Sulawesi (Sulawesiendemic)
Endemic to Sulawesi, South Sulawesi, Lompobatang massif.
