more specimens are gathered, I consider it safer not to lump it 

 with that. Mr. Clarke says he does not see how it differs from 

 polymorphum, var. macrocarpum, but he has made a new 

 species of that. Both Baker and Clarke make two sections of 

 Sagenia, one with " sori in more than two rows between the principal 

 veins, often irregularly scattered," the other with " son in two rows 

 between the principal veins," both forms occur in this species and in 

 polymorphum, and more or less in semibipinnatum and other species, 

 so the definition is only misleading. 



9. Aspidium heterocarpum. (JBedd.) Rhizome creeping 

 widely; stipes solitary, erect, with 

 lanceolate-linear brown persistent 

 scales at the base ; pinnate, very 

 much as in polymorphum, but 

 lower pinnae not bifurcate ; pinnae 

 4-S inches long, narrow-lanceo- 

 late, entire, caudate at the apex, 

 subsessile or very shortly stalked, 

 gemmiparous in the axils ; main 

 veins distant to nearly the margin, 

 areoles copious with free included 

 veinlets ; sori very small on 

 the netted veins, much scattered; 

 indusium reniform or horseshoe- 

 shaped, or sometimes curved or 

 linear, as in Athynum and Asple-
