Wilson 205 ( MICH barcode 1662901!, isoepitypes HAC-LS!, S accession S14-17166!, US barcode 01068904!; image of the epitype available at https://quod.lib.umich.edu/h/herb00ic/x-1662901/mich-v-1662901) .

— Pinguicula jackii Barnhart var. parviflora Ernst (1961: 168) , nom. inval.

Note:—Despite many efforts to locate the holotype of P. lithophytica indicated in the protologue (HAJB-HFC 71790) it was not found in the extant collection of HAJB (Eldis R. Bécquer, pers. comm., 17 April 2023); therefore, it is presumed lost. In order to provide nomenclatural stability a lectotype needs to be designated. According to Art. 9.4 of the ICN, the only known original material for this name is represented by the photographs published in the protologue ( Panfet Valdés & Temple 2008) and are suitable for a lectotype designation. The Figure 2 in the protologue that shows a “Profile view of Pinguicula lithophytica flower” has been selected as lectotype. However, since none of the published photographs show a complete plant, an additional representative specimen has been designated as epitype (Art. 9.9 of the ICN, Turland et al. 2018). The name Pinguicula jackii var. parviflora was invalidly published by Ernst (1961) because the indication of the type was omitted. Ernst (1961) did not cite any examined specimen in his work; therefore, it is impossible to trace original material (Art. 9.4 of the ICN, Turland et al. 2018) for the new name he proposed that remains invalid. Shimai (2017) attempted to validate Ernst’s name by designating a neotype that he published ineffectively, contrary to the requirements of Art. 29.1 of the ICN ( Turland et al. 2018). Additionally, Casper (2019) cited the invalid name under the synonymy of P. jackii but according to the description given by Ernst (1961) and the analysis by Temple et al. (2023) the invalid name represents P. lithophytica and is not related to P. jackii .
