ASPIDIACEAE 



cm. wide, obliquely spreading, shallowly and obtusely lobed, 

 crenate or subentire, minutely scabrous on margin under mag- 

 nification, lower 1 or 2 pairs gradually narrowed and sessile at 

 base, broadly decurrent on the adjacent ones, green above, 

 glaucous beneath; fertile fronds 10-20 cm. long, the pinnae 

 erect, 3-7 cm. long, with sessile, berrylike, globular pinnules 



about 2 mm. across in 2 loose series, the pinnules with 3 or 4 

 thin-indusiate sori surrounded by the involute lobes of the 



pinnules. Sept.-Oct. Wet places; Hokkaido, Honshu, Shi- 



koku, Kyushu; rather common. Korea, Manchuria, s. Ku- 



riles, s. Sakhalin to e. Siberia. The typical variety occurs in N. 

 America.

 indusia inferior, fragile, globose, enclosing the sorus, irregularly parted at the top, or small, basal, and parted into hairlike 



segments; paraphyses absent. About 23 species, in cold regions and high mountains of the N. Hemisphere, also in S. America, 



1 species in S. Africa.
