Hitherto, rheophytism in Bornean Homalomena has been almost exclusively associated with the Chamaecladon Supergroup (sensu Boyce & Wong, 2008), with the only known species recorded as rheophytic from other parts of the genus being the Bruneian and NE Sarawak H. vagans P. C. Boyce (Cyrtocladon Supergroup). However, fieldwork in the highly diverse and species-rich Kanowit-Sarikei river basin of west central Sarawak has revealed an often locally abundant rheophytic species belonging to the Cyrtocladon Supergroup and clearly unmatched with any yet described species, and which we here describe.
