Pteris caudata Linnaeus, Species Plantarum 2: 1075. 1753.

"Habitat in Jamaicae, Dominicae saxosis." RCN: 7810.

Lectotype (Proctor in Howard, Fl. Lesser Antilles 2: 135. 1977): Herb. Linn. No. 1246.15 (LINN) .

Current name: Pteridium aquilinum (L.) Kuhn var. caudatum (L.) Sadeb. ( Dennstaedtiaceae).

Note: Tryon (in Rhodora 43: 55. 1941) indicated type material in LINN referable to var. caudatum (L.) Sadeb. but did not make it clear which specimen was intended. Proctor appears to have been the first to make an explicit choice. Thomson & Alonso-Amelot (in Bot. J. Linn. Soc. 140: 239-243. 2002) provided detailed anatomical information on the type and other material in LINN.
