Calciphilopteris ludens (Wall. ex Hook.) Yesilyurt & Schneider (2010: 56)

Pteris ludens Wall. ex Hooker (1858: 210) . — Litobrochia ludens (Wall. ex Hook.) Beddome (1865 : t. 27), sphalm. “ Litrobrochia ”. — Pellaea ludens (Wall. ex Hook.) Prantl (1882: 419) . — Doryopteris ludens (Wall. ex Hook.) Smith (1875: 289) .

Lectotype (designated here): — MYANMAR: “ Pteris Ludens Wall. Hook. Sp. Fil. P. pedata affinis”, Irawaddy , Wallich 88 in Herbarium Hookerianum, a. 1867 (K-001090040 -image!).

Surprisingly, Cuming 238 from L was also cited as a type of Paltonium dubium Rosenstock (1917: 5) . As was previously mentioned, some of Cuming’s duplicates were distributed with incorrect numbers ( Seregin 2011). Usually, it is impossible to decide with certainty how or when this misnumbering occurred. Rosenstock was aware of Cuming’s legacy, and clearly marked in the protologue that the type bears “ schedula verosimiliter permutata ”. Another Cuming 238 from L was erroneously listed under Diblemma samarensis Smith (1841: 399) , nomen nudum, by Hetterscheid & Hennipman (1984), but this could not be confirmed on the Naturalis webportal with Rosenstock’s annotations. The specimen L-3518284 refers to Calciphilopteris wallichii (isotype).
