Rafflesia banahaw (Rafflesiaceae), a new species from Luzon, Philippines

A new small-flowered species of Philippine Rafflesia from Mt Banahaw in Luzon is described. Rafflesia banahaw is the seventh endemic species of Rafflesia found in the Philippines. It resembles R. baletei, but is different in, amongst other characters, having more confluent wart ornamentations, more numerous and densely packed processes on the disk, and more numerous, slightly immersed anthers. In addition, R. banahaw has glabrous ramenta which are grouped in dense clusters on the inside of the diaphragm and are more or less solitary on the inside of the perigone tube, whereas the ramenta of R. baletei are pubescent and distributed more uniformly.
