38 ADIANTUM PEDATUM. 



it never grows so luxuriantly out of doors, as it does in stove- 

 heat. 



Introduced into the Royal Gardens, Kew, in the year 1809, 

 but probably known in England as early as 1640. 



A hardy deciduous Fern, growing in shady woods. 



Native of North America, from Virginia to Canada, California 

 to Sitka; Unalaschka, and Northern India; about Kamoun, 

 according to Dr. Wallich; and at Jumnotri, according to Dr. 

 Cantor. 



Presl considered the Indian Fern distinct from the North 

 American one, yet there seems to be no real difference. 



The fronds, which are glabrous, are pedate, the branches 

 being linear; pinnate, pinnules membranaceous, dimidiate, oblong- 

 obtuse, cuneate at the base, the upper margin being lobate, or 

 broadly crenate. 



Fronds lateral, on a short creeping rhizoma. 



Sori oblong, solitary. 



Stipes and rachis, ebeneous. 



Length of frond from twelve to eighteen inches; colour a 

 delicate green. 



For plants of this species, I am indebted to Messrs. Rollisson, 

 of Tooting; the Rev. J. Robinson, of Widmerpool, Nottingham- 

 shire; and for fronds to Mr. Norman, of Hull; Mr. R. J. Gray, 

 of St. Thomas', Exeter; and to Mr. J. Henderson, of Wentworth. 



It is in the Fern Catalogues of Messrs. A. Henderson, of 

 Pine-apple Place; Rollisson, of Tooting; Parker, of Hollo way; 

 Cooling, of Derby; Kennedy, of Covent Garden; Sim, of Foot's 

 Cray; Bass and Brown, of Sudbury, Suffolk; Masters, of Can- 

 terbury; E. G. Henderson, of St. John's Wood; and Osborn and 

 Sons, of Fulham.
