Plants and Gymnosperms of Brunei Darussalam (Coode et al., 1996), three species of 
Epirixanthes are reported from the country, namely E. cylindrica Blume, E. elongata 
Blume and E. pallida T.Wendt. During our recent ecological research activities in 
Kuala Belalong (Ulu Temburong National Park, Temburong district), we frequently 
encountered Epirixanthes plants in the lowland dipterocarp forest understorey. 
However, some of the observed plants did not match with any of the three species 
reported from Brunei Darussalam by Coode et al. (1996), indicating they possibly 
belong to unrecorded species. We therefore decided to clarify the taxonomic status of 
these plants and present a revision of Epirixanthes in the country. 
Material and methods 
We examined specimens deposited in BRUN (Brunei National Herbarium) as well 
as our field collections from Brunei Darussalam deposited in OL (Herbarium of the 
Department of Botany at Palacky University in Olomouc). Available duplicates kept 
in K (Royal Botanic Gardens Kew) and AAU (Science Museums, Aarhus University)
