Nepenthes pervillei
''Nepenthes pervillei'' (; after Auguste Pervillé, French plant collector) is the only pitcher plant found in the Seychelles, where it is endemic to the islands of Mahé and Silhouette. It grows in rocky areas near granitic mountain summits,〔 Listed as Vulnerable (VU D2 v2.3).〕 its roots reaching deep into rock fissures. The species has an altitudinal range of 350–750 m above sea level.〔McPherson, S.R. 2009. ''Pitcher Plants of the Old World''. 2 volumes. Redfern Natural History Productions, Poole.〕 Like all members of the genus, ''N. pervillei'' is dioecious, having separate male and female plants.
The mite ''Creutzeria seychellensis'' has been found in the pitchers of ''N. pervillei''.〔Nesbitt, H.H.J. 1979. A new anoetid (Acari) of the genus ''Creutzeria'' from the Seychelles. ''Canadian Entomologist'' 111(11): 1201–1205.〕〔Fashing, N.J. 2002. ''Australian Journal of Entomology'' 41(1): 7–17. 〕
==Taxonomy==
The species was originally described as ''Nepenthes pervillei'' in 1852, but was later placed in the monotypic genus ''Anurosperma'' as ''Anurosperma pervillei'', based on the morphology of its seeds, which differ from the closely allied ''N. madagascariensis'' (and the other members of ''Nepenthes'') in that they lack the 'tails' characteristic of the rest of the genus. However, the more recent taxonomic database of Jan Schlauer subsumes ''Anurosperma'' back into ''Nepenthes''.〔(Carnivorous Plant Database: ''Nepenthes pervillei'' )〕
Long considered one of the more "primitive" species of ''Nepenthes'',〔Macfarlane, J.M. 1927. The Philippine species of ''Nepenthes''. ''The Philippine Journal of Science'' 33(2): 127–140.〕 recent molecular phylogenies have consistently placed ''N. pervillei'' in a basal position within the genus.〔Meimberg, H., P. Dittrich, G.
