Polypodium horridum Linnaeus, Species Plantarum 2: 1092. 1753.

"Habitat in America meridionali." RCN: 7912.

Lectotype (Stolze in Fieldiana, Bot. 37: 42. 1974): [icon] " Filix latifolia ramosa cauliculis nigris et spinosis" in Plumier, Descr. Pl. Amér .: 3, t. 4. 1693.

Current name: Cyathea horrida (L.) Sm. ( Cyatheaceae).

Note: Although Maxon (in Contr. U. S. Natl. Herb. 16: 44. 1912) stated that Plumier’s Traité Foug. Amér . t. 8 (1705) is the type, it was not actually cited in the protologue and is therefore not original material for the name.
