Type. No. 509, Museum d'histoire naturelle, Paris. 



Frond elongate, narrow, linear. Apex acute, or obtusely 

 pointed ; gradually contracted at the base. Midrib well-marked, 

 persisting almost to the apex. Secondary nerves oblique, more or 

 less arched near midrib, then becoming straight, crowded, forming 

 rather narrow, elongate, polygonal meshes. 



The chief characters of this species are the narrow, elongate 

 fronds, with acute apices, and narrow, elongate meshes. The size 

 of the frond varies considerably, from 5-15 cm. in length and 

 10-20 mm. in breadth. 



There has been some doubt as to whether this form of frond is 

 worthy of being regarded as a distinct species. Professor Zeiller 1 

 has upheld the specific rank, while Mr. Seward- has described it
