Ind.: 235. 1768. Lectotypus (designated here): INDONESIA . Java : s.d., Pryon s.n. ( G-PREL [ G00818253 ]!) ( Fig. 7 ). Notes. – In the protologue, BURMAN (1768: 235) referred to a plate in RUMPHIUS’s Herbarium Amboinense (1750: 70, tab. 30, fig. 1) and a Kleynhoff collection in his herbarium. Thus a lectotypification is necessary. The only original material in G-PREL is a Pryon collection from Java that Burman erroneously attributed to Kleynhoff: the polynomial “ Filix non ramosa foliis integris alternis ” cited in the protologue appears in Pryon’s typical handwriting on the sheet. This collections is here designated as lectotype ( Fig. 7 ). The Pryon specimen in G-PREL clearly represents a species of the genus Drynaria (Bory) J. Sm. It corresponds to Drynaria rigidula (Sw.) Bedd. , showing a sterile frond with anastomosing veins and narrow pinnae articulate to rachis. BURMAN (1768) ’s Polypodium simplex predates SWARTZ (1801) ’s P. rigidulum . In order to allow the further use of a well-known and widely used fern name (A. Smith, pers. comm.) and to avoid disadvantageous nomenclatural changes entailed by the strict application of the ICN rules ( TURLAND et al., 2018 : Art. 14.1), a proposal to conserve Swartz’s name over Burman’s is in preparation.
