Three new species combinations are made under Villaria for the Philippine endemics Hypobathrum coriaceum, H. multibracteatum and H. purpureum . Morphological features of these three Hypobathrum species revealed a closer resemblance with Villaria than with Hypobathrum , as the three Philippine endemics possess a unilocular ovary with parietal placentation; a character that is not found in any genera of Octotropideae except in Villaria . Lectotypes and a neotype are selected.
