Sw. and A. portoricensis Maxon, but it differs strongly 
from these in the outline and texture of the divisions of 
the sterile lamina. 
The genus Anemia is represented in the United States 
_ by two species, both of which extend north from tropical 
America. A. adiantijolia (L.) Sw., perhaps the common- 
est species of the genus, is found throughout the West 
Indies and in southern Florida. With its highly modified, 
_ erect basal pinne, it looks at first sight very much like a 
Botrychium. It is much more divided than A. nipeénsis. 
_ A. mexicana Klotsch, which ranges north from Mexico 
into Texas, is like A. adiantifolia, in having the basal 
ee ‘pinne fertile, but the sterile portion is rather thin and 
herbaceous, once pinnate, and thus different from either 
_ of the other species above described.
