Acrostichum ebeneum Linnaeus View in CoL , Species Plantarum 2: 1071. 1753.

"Habitat in Jamaicae sepibus humidiusculis." RCN: 7788.

Lectotype (Tryon in Contr. Gray Herb. 189: 60. 1962): [icon] "Filix non ramosa minima, caule nigro, surculis raris pinnulis angustis, raris, brevibus, acutis, subtus niveis" in Sloane, Voy. Jamaica 1: 92, t. 53, f. 1. 1707.

Current name: Pityrogramma calomelanos (L.) Link View in CoL ( Pteridaceae ).

Note: Tryon (in Contr. Gray Herb. 189: 60. 1962) designated the Sloane plate as lectotype, but subsequent study has shown that this belongs to the taxon known as Pityrogramma calomelanos (L.) Link , into the synonymy of which A. ebeneum should fall. However, Proctor (in Brit. Fern Gaz. 9: 220. 1965; Mem. New York Bot. Gard. 53: 125. 1989) rejected Tryon’s typification in favour of 1245.14 (LINN), a specimen of P. tartarea (Cav.) Maxon. As P. ebenea (L.) Proctor has been adopted for the latter in some works, Tryon (in Taxon 46: 339. 1997) proposed A. ebeneum for rejection. However, the Committee for Pteridophyta (in Taxon 54: 831. 2005) did not recommend rejection, confirmed by the General Committee (in Taxon 55: 800. 2006).
