64 ASPIDIUM UIGTDUM. 



species, easily grown both in a Fernery and under pot-culture. 



A local species, confined to the limestone mountains of West- 

 morland, Lancaster, and York, and even in these localities 

 extending over a small area. In Ireland it has been found 

 in the county of Louth. In England Mr. Moore remarks 

 that it ranges between twelve and fifteen hundred feet above 

 the sea-level. 



It is a native of France, Switzerland, Sardinia, Sicily, Calabria, 

 Germany, Dalmatia, Croatia, Hungary, Morea, Siberia, Asia 

 Minor, California, and Massachusetts; in the two latter countries 

 it attains a larger size. 



The caudex is thick, tufted, scaly, and decumbent. Stipes 

 short, densely scaly. Rachis scaly. Venation branched. Fronds 

 bipinnate, triangularly elongate. Pinnse alternate, triangular in 

 form. Pinnules oblong, base truncate, apex obtuse. Length 

 from one to- two feet; colour dull green, paler on the under 

 side. Numerous minute glands are scattered over the frond, 

 giving it a somewhat glaucous appearance. 



There are no permanent varieties of this species. 



The Aspiditim rigidum is readily recognised from A. Filix- 

 mas, by its more rigid habit, and by the dusty look of its 

 fronds and their less size. 



For plants of A. rigidum I am indebted to Mr. Joseph Side- 

 botham, of Manchester; Mr. Wraight, of Newlands; Mr. Clapham, 

 of Scarbro'; and to Mr. Clarke, gardener to Mr. Wilkinson Dent, 

 of Fiass House, Crosby Pavens worth, Westmorland; to Mr. 

 Clarke my obligations are more particularly due for an extensive 

 series of specimens of this species, gathered in his neighbourhood.
