slightly serrate, the largest ones + 2^|^ cm. long, + 3 mm. broad, 

 dilated at the very base, the lowest hardly reduced. Texture subcoriac- 

 eous; surfaces naked; rachis chanelled above; veins free towards the 

 margin, generally united near the base by a row of anastomosing veinlets 

 so as to form a row of costal areolae on each side. Sori small, in 1 

 row on each side of the costae, solitary on the anastomosing veinlets or 

 on a rudimentary branch excurrent from them.
