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 : 98

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).
