Rafflesia philippensis
''Rafflesia philippensis'' is a parasitic plant species of the genus ''Rafflesia'' that was named by Blanco in his Flora de Filipinas in 1845. ''R. philippensis'' is known only from a mountain located between the provinces of Laguna and Quezon, Luzon where it was first discovered. Its plant host is ''Tetrastigma pisicarpum''. This species went unnoticed since its first description by Blanco but was rediscovered in 2003 by members of the Tanggol Kalikasan, a local environment conservation group in Quezon province who first saw and photographed the open flower of this species. It was brought to the attention of Manuel S. Enverga University (MSEUF), who formed a team composed of students and faculty to document the newly discovered ''Rafflesia'' species.〔
==Morphology==
The mature flower bud of ''R. philippensis'' has a diameter of around 13-16 centimeters. Its fully opened flower has a diameter of 29.3-32 centimeters, placing it in a group composed of other small-sized ''Rafflesia'' species such as ''R. manillana'', ''R. lobata'', and ''R. baletei'', whose open flowers measure an average of 20 centimeters in diameter. The open flower has 9-10 reddish perigone lobes measuring 9.0-10.5 centimeters with 8-12 white oval or elongated warts fused together along the median part of the lobe.〔 ''R. philippensis'' has a distinctive closed diaphragm, same reddish color with the perigone lobes, 3.5-4.0 centimeters thick and measuring 12.5-13.0 centimeters across. The diaphragm’s opening has a diameter of 5.5-6.0 centimeters with an inner white margin lining. The diaphragm’s surface, like the perigone, is blotted with a network of white, thin, elongated and continuous warts.〔
