Rafflesia mixta Barcelona, Manting, Arbolonio, Caballero & PelserThis species was described in the following publication:
Barcelona, J.F., Manting, M.M.E., Arbolonio, R.B., Caballero, R.B., & Pelser, P.B. 2014. Rafflesia mixta (Rafflesiaceae), a new species from Surigao del Norte, Mindanao, Philippines. Phytotaxa 174:272-278.
Rafflesia mixta is a narrow
endemic, known only from the Caraga Region of northeastern Mindanao,
Philippines. The morphology of the flowers of this species most closely
resembles that of R. mira,
but differs in details of the perigone warts and processes, disk color,
and relative size of the diaphragm opening. The etymology of the
specific name is meant to convey a combination of features
characteristics of three other Philippine Rafflesia: the shape and size of the conical processes (R. schadenbergiana), the floral size and sparsely distributed perigone warts (R. speciosa), and the overall resemblance, floral size, faint scent, and diaphragm and ramenta morphology (R. mira).
This discovery brings the total number of Philippine Rafflesia species
to twelve, of which four are found on the island of Mindanao.
