Pinguicula jackii Barnhart (1931: 61) .

Type (lectotype, designated here):— CUBA. Province of Santa Clara [Cienfuegos]: Las Lagunas, Buenos Aires , on perpendicular rocks, north exposure, ca. 762 m, 5 December 1928, J.G. Jack 6794 ( US barcode 00136349!; image of the lectotype available at https://ids. si.edu/ids/deliveryService/id/ark:/65665/m39361283886e54dd487ea4826817c8673/1024) .

Note:— The protologue lists three gatherings: Jack 6794 (5 December 1928), Bailey [12443] (17 March 1929) and Jack [7942] (25 April 1930); it specifies Jack 6794 as the type but did not use the term holotype or mention any herbarium housing the specimen(s). Fresh material from the type locality was also used by Barnhart (1931) when preparing the description and by Mary E. Eaton who prepared the accompanying illustration. Casper (2019) cited the “ holotype ” as housed at NY; however, there is no material of Pinguicula collected by Jack in the extant NY collection ( Matthew Pace , pers. comm., 15 November 2021). Specimens that match the collections cited by Barnhart (1931) have been traced at US (00136349! [ Jack 6794] and 01068927! [ Jack 7942]), BH (BH000011923! [ Bailey 12443]), and NY (02852453! [ Bailey 12443]). Moreover, another one of Jack’s specimens with the same number of that on the specified type was found at US (01068928!) but it bears a different date (7 March 1929); therefore, it seems that Jack’s number (6794) may have been applied to some of his P. jackii ’s specimens despite it having originated from different gatherings. Shimai (2017) cited the specimen “ Jack 6794, 5 December 1928 ” at US as “ holotype ”; however, Shimai’s work conflicted with Arts. 7.10, 7.11 and 29.1 of the ICN ( Turland et al. 2018) and lectotypification of P. jackii remained necessary. Herewith, the specimen Jack 6794 ( US barcode 00136349!) is designated as the lectotype; and, since the date on the second specimen Jack 6794 at US is different, it is disregarded as isolectotype.
