The upper portion of the stipe of this is thick, smooth, and fur- 

 rowed in front, with a very few scattered, raised points on its surface. 

 The fronds are large, lax, and bipinnate, with the pinnules pinnatifid 

 nearly to the rhachis; the primary divisions are distant, and the 

 main rhachis towards the extremity slender and flexuose, and, with 

 the secondary one, hairy on the upper side, while on the costa 

 beneath are scattered chaffy, lacerated, whitish, small scales. Seg- 

 ments oblong-linear, slightly falcate and dentate, bearing from 10 to 

 18 sori, which are axillary on the forcings of the veins.
