Mazumdar, Jaideep, Callmander, Martin W. & Fumeaux, Nicolas, 2019, Typification and nomenclature of the ferns described in N. L. Burman’s Flora Indica, Candollea 74 (1), pp. 93-109 : 102

Polypodium radicans Burm. f. , Fl. Ind.: 233, tab. 66, fig. 3. 1768.

≡ Nephrolepis radicans (Burm. f.) Kuhn in Ann. Mus. Bot. Lugduno-Batavi 4: 285. 1869.

Lectotypus (designated here): INDONESIA. Java: s.d., Pryon s.n. ( G-PREL [ G00800108 ]!).

Notes. – BURMAN (1768: 233) cited in the protologue a Pryon collection, a reference to his father’s Thesaurus Zeylanicus (1737: 98) and a plate (tab. 66, fig. 3) ( Fig. 1 ).

Asingle specimen of Pryon is present in G-PREL (G00800108). HOVENKAMP & MIYAMOTO (2005: 308) and HOVENKAMP (2013a: 65) cited this specimen as type but failed to indicate the institution of deposit in 2005 and the term “ lectotype ” both in 2005 and 2013. Thus, none of these citations can be accepted as valid lectotypification ( TURLAND et al., 2018: Art. 9.22, 9.23). The lectotypification is based here on the single specimen of original material present in G-PREL [G00800108].
