130 PTERTS CRENATA. 



Sori continuous, extending along the decurrent portions to 

 the apex of the pinnules, and, although margined, never round 

 the upper edges, being always on the under side. Indusium 

 prickly. 



Length of frond from twelve to eighteen inches; colour dull 

 green. 



Stipes circular on the under side, and green; hollowed on 

 the upper, and darker green. In a frond in my collection, 

 twenty inches in length, the stipes was nearly twelve inches. 



My thanks are due to Mr. Stratton, of the Cambridge Botanic 

 Gardens, and to Mr. Henderson, of Wentworth, for plants of 

 this species; and to M. Schott, of the Imperial Gardens, Vienna, 

 for fronds. 



The following Nurserymen include it in their Catalogues: — 

 Messrs. Booth, of Hamburg; Sim, of Foot's Cray; Parker, of 

 Holloway; Veitch, Jun., of Chelsea; A. Henderson, of Pine- 

 apple Place; Stansfield and Son, of Todmorden; and Kennedy,
