A new species of Philippine Rafflesia is described. Rafflesia leonardi is the eighth species of Rafflesia described from the Philippines and the fourth species from Luzon Island. It most closely resembles R. lobata and R. manillana in perigone colour and wart ornamentations and in the wide aperture relative to diaphragm diameter. It is, however, different from both of these and other Philippine Rafflesia species in its flower size and disk that lacks or has rudimentary processes.
