Note:— Pinguicula elongata was described by L. Benjamin based on material collected by W. Purdie and sent to W. J. Hooker. In the protologue, Benjamin (1847: 318) referred to a specimen from “Herb. Hooker” collected by Purdie, but the locality cited ( Jamaica) is clearly an error since P. elongata has never been recorded outside the Colombian and Venezuelan mountains. Fernández-Pérez (1964) and Casper (1966) cited the “ holotype ” of P. elongata : “Sierra Nevada de Santa Marta, Purdie 1045” as housed at K (Purdie 1045); although Casper did not see this specimen. Purdie traveled from Jamaica to Colombia in 1844 and many specimens he sent to Hooker are housed at K in the Herbarium Hookerianum. Many Purdie’s sheets bear labels in Hooker’s hand with information on locality and year of the gatherings probably extracted from Purdie’s letters; and specimens from Santa Marta (Sa. Martha) Colombia, are dated mostly as 1845. Unfortunately, Purdie seems never to have numbered his specimens ( Ewan 1948) which makes impossible to trace any particular duplicate material; on the other hand, maybe a misreading of Hooker handwritting led Fernández-Pérez to take the year 1845 as a Purdie’s number “1045”. We could not find the specimen referred as holotype nor other with the exact label information cited by Fernández-Pérez (1964) and Casper (1966); nonetheless a specimen traced at the Herbarium of Trinity College Dublin ( TDC) partially fits in this information. This specimen, collected by Purdie at Santa Marta, is not identified, but it clearly represents P. elongata . We cannot assure whether this specimen was examined by Benjamin or not, but according to Art 9.3(c) of the ICN ( McNeill et al. 2012) it can be considered as an original material; therefore, we herein designate it as lectotype.
