Ophioglossum pedatum Burm. f., Fl. Ind.: 227, tab. 66, fig. 1. 1768.
≡ Lygodium pedatum (Burm. f.) Sw., Syn. Fil.: 154. 1806 [nom. illeg.] [non L. pedatum Sw. in J. Bot. (Schrader) 1800(2): 106. 1801].
Lectotypus (designated here): INDONESIA. Java: s.d., Pryon s.n. (G-PREL [G00800094]!).
= Lygodium circinnatum (Burm. f.) Sw., Syn. Fil.: 153. 1806.
Notes. – The original material of this species includes a plate (BURMAN, 1768: tab. 66, fig. 1) (Fig. 1) and a single specimen in G-PREL [G00800094] collected by Pryon from Java. Alectotype is therefore designated on the Pryon specimen in G-PREL.
MERRILL (1921: 336) erroneously recognized the illegitimate name Lygodium pedatum over L. circinnatum following page priority. The name L. circinnatum is currently generally accepted for this species (ALSTON & HOLTTUM, 1959; HOLTTUM, 1959a).
