which was published first in 1809. It includes also Robert 
Brown's genus Stegania published in 1810. Christensen} reduces 
Lomaria (including Stegania) toa subgenus of Blechnum and in this 
Subgenus recognizes one hundred species. Including the two 
North American species placed under Lomaria by Willdenow, 
thirty-six species have been described from North America under — 
the generic name Lomaria; this does not include the species since 
Placed in the genera Stenochlaena, Salpichlaena, and Plagiogyra. 
. Twenty-five North American species are recognized by the writer; 
these five are new and one must bear a new name. 
_ Though not included by Linnaeus in his Species Plantarum, 
the genus Struthiopteris is much older than 1753. Trevisant 
Bives 1561 for the earliest use of this name and cites Valerius 
Cordus§ as using Struthiopteris to distinguish Osmunda Spicant L. 
mes later used in this serise by several others. The most 
inent was probably Haller;|| in 1742 he used the monomial
