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;} this species Linnaeust 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 
Scopolif]) published Struthiopteris Spicant. The correct name 
for the type species of this genus is therefore S. Spicant (L.) Weis. 
Willdenow,** in 1787, referred to Struthiopteris Spicant Weis asa 
synonym of Osmunda Spicant. Swartztt 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 add 
somewhat to the confusion regarding the correct name of this 
genus. Bernhardiff published a similar name, Struthopterts, for 
three other ferns of the Linnaean genus Osmunda (O. cinnamomet, 
O. Claytoniana, and O. regalis) with the caution that it was not © 
be confounded with Struthiopteris Hall. Willdenow§§ published 
Struthiopteris for Osmunda Struthiopteris L. and an undescri 
‘ 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: Bernhardil||| to Asplenium, Willdenow {1 to Acros- 
tichum, and Swartz *** to Blechnum. Swartz t{talso placed several
