Pinguicula planifolia Chapman (1897: 303)

Protologue locality:—Shallow ponds, west Florida, near the coast.

Type (lectotype, designated here):— [ UNITED STATES OF AMERICA]. Shallow ponds, Apalachicola , Florida, 9 March 1896, [ A. W. Chapman] 4353a ( WU No. 0075582 [digital photo!], isolectotypes L No. 502640 barcode L.2828061 [digital photo!], L No. 502640 barcode L.2828062 [digital photo!], PH ex PENN No. 16941, Z No. 5358 barcode Z-000023876 [digital photo!]; image of the lectotype is available at http://herbarium.univie.ac.at/database/detail.php? ID =467800) .

Note:— Casper (1966: 84) cited a specimen from NY and wondered if it could be the holotype of the name Pinguicula planifolia : “Specimen sub nomine P. australis S. Fl. (Chapman not Nuttall)– NY, leg. Chapman; forsitan Holotypus?!”, this specimen was not found in our searches at NY; although, two similar specimens from the Herb. Nuttall were traced at BM ( BM 001025253) and PH ( PH 00031074), but it seems to be not an original material on which Chapman based the description of P. planifolia . According to the locality in the protologue of P. planifolia , we have traced five specimens from the Biltmore Herbarium (Distribution of the duplicates of the Chapman Herbarium) housed at the herbarium of the Academy of Natural Sciences ( PH), the herbarium of the University of Vienna ( WU), the National Herbarium of the Netherlands ( L) and the herbarium of the University of Zurich ( Z). Those sheets, according to its origin and the locality and date: “Shallow ponds, Apalachicola, Florida, March 9 th, 1896 ”, should be considered original materials aswell as syntypes for the name Pinguicula planifolia according to Arts. 9.3(a, c) and 9.5 of the ICN ( McNeill et al. 2012) respectively. Two other specimens from Biltmore Herbarium traced by us at L ( Pinguicula lutea Walter : L.2828037 and L.2828041), seems to be part of the voucher material used by Chapman for the treatment of Pinguicula in the third edition of the Flora of Southern United States ( Chapman 1897). The label’s information on this P. lutea material fits in the information that Chapman gave in his work for this species; and, analyzing the labels of both sets of specimens ( P. planifolia and P. lutea ) derived from Biltmore Herbarium, there is no doubt that all of them have come from the same collection (Chapman Herbarium). Therefore, as those materials are in accordance with Chapman’s description: “Smoothish; leaves lanceolate or oblong, flat; corolla 5-parted, the wedge-obovate lobes 2-cleft, acutish; spur sac-like, obtuse. Scapes 1º high. Corolla 1’ wide”, and no other Chapman specimen has been traced, we have selected the specimen held at WU, which bears the better preserved fertile material among the examined specimens, as lectotype and the specimens held at L, PH, and Z are cited as isolectotypes following Rec. 9 C of the ICN ( McNeill et al. 2012).
