132 POLYPODIUM CATHARINE. 



The fronds, which are glabrous and broadly lanceolate, stand 

 nearly erect; pinnatifid, the segments being oblong-obtuse. 



Length of frond from twelve inches to two feet; colour a 

 dull heavy green. 



Fronds articulated on a creeping rhizoma, the rhizoma being 

 very thickly covered with imbricated peltate acuminate scales 

 of a brown colour. 



Sori biserial and prominent. 



I am indebted to Messrs. Rollisson, of Tooting, for a plant 

 of this species; and to Mr. Henderson, of Wentworth, and to 

 Mr. Norman, of Hull, for fronds. 



It is in the catalogues of the following Nurserymen: — Veitch, 

 Jun., of Chelsea; Kennedy, of Covent Garden; A. Henderson, 

 of Pine-apple Place; Parker, of Holloway; RoUisson, of Tooting; 

 and Sim, of Foot's Cray. 



The illustration is from a plant in my own collection.
