Adiantum lunulatum Burm. f., Fl. Ind.: 235. 1768.

Lectotypus (designated by MERRILL, 1921: 334): INDONESIA. Java [?]: s.d., Anon. s.n. ( G-PREL [ G00800009 ]!).

= Adiantum philippense L. , Sp. Pl.: 1094. 1753.

Notes. – The protologue of Adiantum lunulatum included references to plates from PETIVER (1702 – 1709)’s Gazophylacii Naturae and RHEEDE (1678 – 1693)’s Hortus Indicus Malabaricus, as well to a specimen (or possibly more) received from Malabar or Java (“ Habitat in Malabara & Java, unde missa ”).

MERRILL (1921: 334) stated that: “the actual type was apparently a Javan specimen, the Malabar reference being apparently added either from Avenka Rheede Hort. Malabar. 12: 72, tab. 40, or from Petiver Gaz. tab. 54, f. 10, both cited as representing the species”. As a single specimen of original material (from unknown origin but bearing references to both plates) is present in G-PREL [ G00800009 ], Merrill’s implicit lectotypification is accepted here.

This was overlooked by MORTON (1974: 370), who selected the same specimen as lectotype.
