the frond becoming gradually narrower towards the apex j 

 obtusely-elongate. 



Length of frond from one to two feet; glaucous underneath. 



Sori uniserial. 



Link, in his "Filicum Species," remarks, "Nostrum est P. 

 areolatum, Schiedei, nam Willdenowii planta minor est subtus 

 non glaucescens, nee tam profunde pinnatifida. Polyp, sporado- 

 carpuTTij Willd. sec. Hbr., raajus quidem est, et non tam profunde 

 pinnatifidum, sed tamen valde affine et vix specie diversum." 



For a plant and fronds of this species I am indebted to 

 Mr. Henderson, of Wentworth. 



It is in the Catalogue of Mr. Kennedy, of the Bedford 

 Conservatory, Covent Garden. 



The illustration is from a frond forwarded by Mr. Henderson, 

 of Wentworth.
