258 Broadhurst: Struthiopteris in North America 



Osmunda Spicant L. by Scopoli, Haller, and Weis. In 1760 

 Scopoli* used the monomial Struthiopteris, and included under it 

 number 844 of Linnaeus ;f this species Linnaeusf had meanwhile 

 named Osmunda Spicant. Therefore, by citation, the correct name 

 of this genus is Struthiopteris (Hall.) Scop. 



Haller, § in 1768, again used the monomial Struthiopteris, 

 referred to Scopoli's work of 1760, and cited, by number, Osmunda 

 Spicant of Linnaeus. The first, however, to publish a binomial 

 under Struthiopteris was Weis,|| who in 1770 (two years before 

 Scopoli^i) published Struthiopteris Spicant. The correct name 

 for the type species of this genus is therefore 5. Spicant (L.) Weis. 

 Willdenow,** in 1787, referred to Struthiopteris Spicant Weis as a 

 synonym of Osmunda Spicant. Swartzft later included Struthi- 

 opteris in a list of generic synonyms for this species. Neither 

 Swartz, however, nor Willdenow adopted it. 



In the first decade of the nineteenth century four writers, 

 Bernhardi, Robert Brown, Swartz, and Willdenow, each added 

 somewhat to the confusion regarding the correct name of this 

 genus. Bernhardi |t published a similar name, Struthopteris, for 

 three other ferns of the Linnaean genus Osmunda (O. cinnamomea, 

 O. Claytoniana, and 0. regalis) with the caution that it was not to 

 be confounded with Struthiopteris Hall. Willdenow§§ published 

 Struthiopteris for Osmunda Struthiopteris L. and an undescribed 

 " Struthiopteris from Pennsylvania" (which he described in 1810 

 as S. pennsylvanica). Three of these workers transferred Osmunda 

 Spicant L., the type of the genus Struthiopteris, to other estab- 

 lished genera: Bernhardi|] | to As plenium, Willdenow It to A cros- 

 tichum, and Swartz *** to Blechnum. Swartz f ft/also placed several
