High Quality Content by WIKIPEDIA articles! Rafflesia cantleyi is a parasitic plant species of the genus Rafflesia. It can be found in Peninsular Malaysia and Pulau Tioman, an island off the east coast of Peninsular Malaysia. This species is almost identical to R. hasseltii, except for the number of warts on the perigone lobes of the two species. Another distinctive feature of R. cantleyi is its ability to form flowers on the aerial portions of its host Tetrastigma. R. cantleyi was named after Nathaniel Cantley, curator of the Singapore Botanic Gardens. Rafflesia is a genus of parasitic flowering plants. It was discovered in the Indonesian rain forest by an Indonesian guide working for Dr. Joseph Arnold in 1818, and named after Sir Thomas Stamford Raffles, the leader of the expedition. It contains approximately 27 species (including four incompletely characterized species as recognized by Meijer 1997), all found in southeastern Asia, on the Malay Peninsula, Borneo, Sumatra, and the Philippines. The plant has no stems, leaves or true roots. It is an endoparasite of vines in the genus Tetrastigma (Vitaceae), spreading its root-like haustoria inside the tissue of the vine.
