''Nepenthes eymae'' is a tropical pitcher plant endemic to Sulawesi, where it grows at elevations of 1000–2000 m above sea level. It is very closely related to ''N. maxima'', from which it differs in its wine glass-shaped upper pitchers.〔McPherson, S.R. 2009. ''Pitcher Plants of the Old World''. 2 volumes. Redfern Natural History Productions, Poole.〕 The specific epithet ''eymae'' honours Pierre Joseph Eyma, a Dutch botanist who worked extensively in the Dutch East Indies and who originally discovered the species.〔〔van Steenis-Kruseman, M.J., ''et al.'' 2006. (Cyclopaedia of Malesian Collectors: Pierre Joseph Eyma ). Nationaal Herbarium Nederland.〕 ==Botanical history== ''Nepenthes eymae'' was discovered in central Sulawesi by Dutch botanist Pierre Joseph Eyma in 1938.〔D'Amato, P. 1993. (''Nepenthes eymai''. ) ''Carnivorous Plant Newsletter'' 22(1–2): 21.〕 Eyma's original material of this species includes the herbarium specimen ''Eyma 3968'', which bears a male inflorescence.〔 ''Nepenthes eymae'' was formally described by Shigeo Kurata in a 1984 issue of ''The Journal of Insectivorous Plant Society''.〔〔(''Nepenthes eymae'' Shigeo Kurata ). International Plant Names Index (IPNI).〕 The holotype, designated as ''Kurata, Atsumi & Komatsu 102a'', was collected on the northern spur of Mount Lumut in Central Sulawesi,〔Schlauer, J. (''Nepenthes eymae'' ). Carnivorous Plant Database.〕 at an altitude of 1850 m, on November 5, 1983.〔 A series of isotypes (''Kurata, Atsumi & Komatsu 103'', ''104'', and ''105'') was also listed by Kurata.〔 The repository of these four specimens is not indicated in the type description and they have not been located, but if they were deposited in a public institution this is likely to have been the herbarium of the Nippon Dental College (NDC).〔Cheek, M.R. & M.H.P. Jebb 2001. Nepenthaceae. ''Flora Malesiana'' 15: 1–157.〕 Despite this, the species name is valid per Article 37 of the ''International Code of Botanical Nomenclature'', and Kurata's description includes an illustration of the holotype on page 44.〔 Kurata published the species with the specific epithet ''eymai'', honouring Pierre Joseph Eyma.〔 Other authors later noted that although Eyma was male, the name is feminine, and so the epithet was emended to ''eymae''.〔 Almost concurrently with Kurata's publication, John Turnbull and Anne Middleton described the same species under the name ''N. infundibuliformis'' in the journal ''Reinwardtia''.〔 Kurata's description was published on February 6, whereas Turnbull and Middleton's was printed four days later, on February 10.〔 As such, the name ''N. eymae'' holds nomenclatural priority and ''N. infundibuliformis'' is considered a heterotypic synonym.〔〔 A similar situation involved the descriptions of ''N. glabrata'' and ''N. hamata'' by the same authors.〔〔 Turnbull and Middleton's description is based on the specimen ''J.R.Turnbull & A.T.Middleton 83148a'', which was collected by the authors on September 20, 1983, from Mount Lumut Kecil in Sulawesi at the coordinates , at an altitude of 1500 m.〔 In their description of the species, Turnbull and Middleton stated that the type material was deposited at Herbarium Bogoriense (BO), the herbarium of the Bogor Botanical Gardens, but Matthew Jebb and Martin Cheek were unable to locate it and wrote that it "appear() not to have been deposited at Bogor as stated".〔 In addition to the herbarium specimens of ''N. eymae'' mentioned here, a number of others have appeared in the literature. Most authors regard ''N. eymae'' as a distinct species and it has been treated as such in all major monographs on the genus, including Matthew Jebb and Martin Cheek's "A skeletal revision of ''Nepenthes'' (Nepenthaceae)" (1997)〔Jebb, M.H.P. & M.R. Cheek 1997. A skeletal revision of ''Nepenthes'' (Nepenthaceae). ''Blumea'' 42(1): 1–106.〕 and "Nepenthaceae" (2001),〔〔 as well as Stewart McPherson's ''Pitcher Plants of the Old World'' (2009).〔 Nonetheless, some authors have expressed doubt that it merits distinction from ''N. maxima'' at the species level.〔〔D'Amato, P. 1998. ''The Savage Garden: Cultivating Carnivorous Plants''. Ten Speed Press, Berkeley.〕〔〔Evans, D.P. 2009. (New cultivars: ''Nepenthes maxima'' ‘Lake Poso’ ). ''Carnivorous Plant Newsletter'' 38(1): 18–22.〕 In ''Pitcher Plants of the Old World'', McPherson wrote that "the specific status of ''N. eymae'' seems warranted since the two taxa (and ''N. maxima'' ) appear to occur both together and in isolated, self-sustaining communities".〔 Whatever the status of this taxon, the vast majority of plants cultivated under the name ''N. eymae'' do not exhibit the abruptly contracted upper pitchers commonly associated with it.〔Mey, F.S. 2011.
