linear, coutinuous on the costal anastomose, elevated in 

 the form of a ridge. Inchismm linear, laterally attached 

 on the exterior side of the receptacle, its inner margin 

 free, becoming reflexed, coriaceous, persistent.

Obs. — The type of this genus was originally desci-ibed as 

 a species of Blechmim, under which genus I placed it in 

 1841, my first arrangement, but on account of its very 

 distinct habit I now deem it best to separate it from 

 BlecJinum. With Lomaria Boryana it agrees in having 

 a stout arborescent caudex, but differs in having regular 

 pinnatifid pinns, which are articulate with the raohis.

Vernation fasciculate, erect, arborescent, 2 to 4 feet high. 

 Fronds pinnate, rarely sub-bipinnate, 2 to 3-^ feet long ; 

 pinnae linear lanceolate, 4 to 6 inches long, sub-sessile, 

 base truncate above, auriculated below ; margin crenato 

 serrulate. Veins flabellately forked, free exteriorly, the 

 lower venules short and angularly anastomosing, forming 

 a row of oblique costal areoles. Sporangia produced on 

 the angular anastomoses, and lower part of the exterior 

 free venules, confluent, constituting a broad, co-mpound, 

 continuous or sub-interrupted, transverse naked sorus.
