85. Polypodium japonicum Thunb. ex Houtt., View in CoL

Nat. Hist. II(14): Aanwyz. Plaat. [2], 167, tab. 98, fig. 3. 1783.

Lectotypus (designated here by Wijnands): JAPAN: Thunberg s.n. ( G-PREL [ G00818090 ]!; isolecto-: UPS- THUNB n° 24493 and n° 24494 images seen).

= Polypodium falcatum Thunb. View in CoL ex L. f., Suppl. Pl.: 446. 1782. ≡ Cyrtomium falcatum View in CoL (Thunb. ex L. f.) C. Presl, Tent. Pterid.: 86. 1836.

Lectotypus (designated here by Callmander): JAPAN: Thunberg s.n. (UPS-THUNB n° 24493 image seen; isolecto-: G-PREL [ G00818090 ]!, UPS-THUNB n° 24494 image seen).

Notes. – A single element representing original material is in the Japan herbarium in G-PREL. It is a very good match for the plate and is designated here as the lectotype of Polypodium japonicum . Houttuyn annotated the specimen as “ Polypodium japonicum Thunb. vel falcatum Fl. Japon. p. 336, tab. 36”, so he apparently compared his plant with a manuscript of Thunberg’s work that was published in 1784, after the publication in the Natuurlijke Historie had been completed. He did not cite LINNAEUS f. (1782) where P. falcatum Thunb. ex L. f. was published, based on the same duplicates in the Thunberg herbarium. Two collections of original material are present in UPS-THUNB. The lectotype of P. falcatum designated here is the most complete sheet (UPS-THUNB n° 24493).
