Homalomena selaburensis P.C.Boyce & S.Y.Wong is described as a taxonomic novelty of the Homalomena Supergroup from forested Karst limestone in Samarahan Division, SW Sarawak, and compared with the most similar species described so far from Sarawak (Homalomena passa S.Y.Wong & P.C.Boyce), and from Peninsular Malaysia (Homalomena curvata Engl.). An identification key is provided and Homalomena selaburensis is illustrated from living plants.

Full Text

The Homalomena Supergroup (sensu Boyce & Wong, 2008) is primarily a continental tropical Asian taxon, with only limited representation in the Indomalayan archipelago. Nonetheless, fieldwork on Borneo has revealed several locally restricted species, all novel (e.g., Baharuddin & Boyce, 2010; Wong et al., 2013), and which we are describing as they flower in cultivation. One such further novelty is here described.
