Two taxonomically novel species of Homalomena (Araceae: Homalomeneae), H. prolixa S. Y. Wong \& P. C.\ Boyce and H. scutata S. Y. Wong \& P. c.\ Boyce, both of doubtful taxonomic affinity, are described from SW Sarawak, and from Brunei and adjacent NE Sarawak, Borneo, respectively. Both occur as lithophytes on forested sandstone bluffs.

A new rheophytic species of Schismatoglottis, S. persistens S. Y. Wong \& P. C. Boyce is described from Sri Aman Division, Sarawak, Malaysian Borneo. It is remarkable in the genus by the combination of a creeping, rooting, rhizome-like stem and persistent ligules at the tip of the petiolar sheath.

Nineteen new species of Bucephalandra Schott are described: B. akantha S. Y. Wong \& P. C.\ Boyce, sp. nov., B. aurantiitheca S. Y. Wong \& P. C.\ Boyce, sp. nov., B. belindae S. Y. Wong \& P.

C.\ Boyce, sp. nov. Furthermore, three pre-existing species names are transferred from Microcasia Becc. to Bucephalandra: B. elliptica (Engl.) S. Y. Wong \& P. C.\ Boyce, comb. nov. (\≡ Microcasia elliptica Engl.), B. muluensis (M. Hotta) S. Y. Wong \& P. C.\ Boyce, comb. nov. (\≡ M. muluensis M. Hotta) and B. oblanceolata (M. Hotta) S. Y. Wong \& P. C.\ Boyce, comb. nov. (\≡ M. oblanceolata M. Hotta). Together these changes take Bucephalandra to 27 species. An updated generic description is provided, and a key to all species is offered. All species dealt with taxonomically and nomenclaturally are illustrated from living plants, and with comparative plates of the spadices. Where possible scientific names are correlated to nomenclature used by commercial suppliers. Remaining taxonomic problems are highlighted, and foci for further study suggested. Notes on the role of the motile interstice staminodes are supplied.
