"Habitat in America septentrionaliore." RCN: 7777. Lectotype (Proctor, Ferns Jamaica : 212. 1985): [icon] " Filix minor ruffa lanugine tota obducta, in pinnas tantum divisa, raras, non crenatas subrotundas" in Sloane, Voy. Jamaica 1: 87, t. 45, f. 1. 1707. - Typotype : Herb. Sloane 1: 96 ( BM-SL ) . Current name: Hemionitis rufa (L.) Sw. ( Pteridaceae ). Note: Specific epithet spelled "ruffa" in the protologue. Although Acrostichum rufum L. (1759) has been treated as a new combination based on Pteris rufa by some authors, this is unjustified as there is no direct reference to the earlier name in the protologue of A. rufum , and P. rufa also appears in the same work (1759), as noted by Tryon & Stolze (in Fieldiana, Bot. 22: 47. 1989). Linnaeus did, however, treat the two names as synonymous in 1763.
