Osmunda struthiopteris Linnaeus, Species Plantarum 2: 1066. 1753.

"Habitat in Suecia, Helvetia, Russia, Norvegia." RCN: 7762.

Lectotype (Jonsell & Jarvis in Nordic J. Bot. 14: 149. 1994): Herb. Burser XX: 29 (UPS) .

Current name: Matteuccia struthiopteris (L.) Tod. ( Dryopteridaceae).

Note: Both Copeland (in Univ. Calif. Publ. Bot. 16: 54. 1929) and Bobrov (in Novosti Sist. Vyssh. Rast. 21: 7. 1984) indicated 1244.13 (LINN) as type, but this is an Arduino collection, not received by Linnaeus until long after 1753 and consequently not original material for the name.
