Abstract 
 A new outstanding species of the parasitic plant, Rafflesia tiomanensis, was discovered on Pulau Tioman, Pahang, Malaysia. R. tiomanensis is characterised by small discrete warts on the perigone lobes, the absence of warts on the diaphragm upper surface, lack of processes on the disk, the absence of disk rims, and the irregular shape whose opening aperture is variably lobed. All other species in Peninsular Malaysia have warts on the diaphragm upper surface, processes, and disk rims. This new species is thus entirely unique. The species description, colour plates, and provisional conservation status are provided.

Key words: endemic, morphology, new species, Pulau Tioman, Rafflesia tiomanensis.
