Ophioglossum circinnatum Burm. f., Fl. Ind.: 228. 1768.

≡ Lygodium circinnatum (Burm. f.) Sw., Syn. Fil.: 153. 1806.

Lectotypus (designated by HOLTTUM, 1959a: 59): INDONESIA. Java: s.d., Pryon s.n. (G-PREL [G00818001]!).

Notes. – In the protologue, BURMAN (1768: 228) cited a Pryon specimen and two illustrations (RUMPHIUS, 1750: 75 (sphalm. “76”), tab. 33; PETIVER, 1702 – 1709: tab. 64, fig. 10).

HOLTTUM (1959a: 59) mentioned as type “ Java, herb. Burman (G, not seen)”. As the only original material in G-PREL is a Pryon collection from Java [G00818001], Holttum’s statement is accepted as implicit lectotypification.
