 The genus Epirixanthes Blume is revised for Brunei Darussalam. Four species are recognised for the country: Epirixanthes cylindrica Blume, E. elongata Blume, E. kinabaluensis T.Wendt and Epapuana J.J.Sm., with the two latter species being newly recorded for the Brunei flora. A single collection from Brunei that was formerly identified as Epirixanthes pallida T.Wendt is now confirmed as Epapuana. A revised key for the genus is included.
