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 : 94

Acrostichum longifolium Burm. f. , Fl. Ind.: 228. 1768.

≡ Pyrrosia longifolia (Burm. f.) C.V. Morton in J. Wash. Acad. Sci. 36: 168. 1946.

Lectotypus (designated by HOVENKAMP, 1986: 209): INDONESIA. Java: s.d., Pryon s.n. ( G-PREL [ G00801094 ]!).

Notes. – In the protologue, BURMAN (1768: 228) cited a Pryon specimen and two illustrations ( PETIVER, 1702 – 1709: tab. 61, fig. 2, 4).

HOVENKAMP (1986: 209) was the first to mention a Pryon specimen at Gas holotype. This should be considered as an implicit lectotypification, as a single Pryon specimen representing original material is present in G-PREL.

An uncited specimen [G00801093] from unknown origin is also extant in G-PREL: it bears a reference to one of Petiver’s illustrations (tab. 61, fig. 4. Tab. 61, fig. 2 is mentioned on the Pryon specimen), as well as the name of the new species, both in N.L. Burman’s handwriting, and thus should be regarded as original material.
