ABSTRACT:
Piptospatha bella S. Y. Wong & P. C. Boyce and Piptospatha lurida S. Y. Wong & P. C. Boyce are described and illustrated from Sarawak, Malaysian Borneo. Their recognition takes Piptospatha to 18 described species. Piptospatha lurida is most similar to P. burbidgei, a species formerly allotted its own genus, Gamogyne, later made into a section of Piptospatha. Notes on Gamogyne are provided and a correction to published information on the placentation of Gamogyne offered.
