Acrostichum heterophyllum Linnaeus, Species Plantarum 2: 1067. 1753.

"Habitat in Malabaria, Zeylona, Africa." RCN: 7767.

Lectotype (Sledge in Bull. Brit. Mus. (Nat. Hist.), Bot. 2: 135. 1960): Herb. Hermann 3: 57; 4: 29, No. 378 (BM-000628016).

Current name: Pyrrosia heterophylla (L.) M.G. Price ( Polypodiaceae).

Note: In designating a type, Sledge did not distinguish between the material mounted in volumes 3 and 4 of the Hermann herbarium. However, as the material appears to be part of a single gathering, Art. 9.15 applies and this is accepted as a formal typification.
