Rafflesia banahawensis Madulid, Villariba-Tolentino & Agoo
This Rafflesia species is named after the mountain, Mt. Bahahaw in Luzon, Philippines, where it was first discovered.
Known from only five locations on Mt. Banahaw on Luzon, this species grows on Tetrastigma roots at or below the ground level. It is one of the small-flowered Rafflesia species, with floral diameters ranging from 17 to 27 cm. It most resembles R. baletei from the Bicol region, Camarines Sur Province in southern Luzon. It differs from that species in several morphological features such as wart ornamentation, the color and density of the processes, and ramenta grouping inside the diaphragm.
