64 ASPLENIUM rONTANUM. 



has been found growing wild there can be no doubt, we are 

 therefore almost bound to accept it as a British plant. A very 

 handsome dwarf Fern. 



Exceedingly rare, having only been found in the following 

 places: — Hamersham Church, Bucks.; Wybourn, Westmoreland; 

 "VVharnclifFe Wood, Yorkshire; Cavehill, near Belfast; Stone- 

 haven, Kincardineshire; Tooting, Surrey; Isle of Purbeck; one 

 situation in Wales; and recently at Petersfield, Hampshire. 



Found in Spain, France, Italy, Switzerland, Germany, 

 Hungary, Scandinavia, and Siberia. 



Fronds of a narrow-lanceolate form, bipinnate, and broadest 

 above the middle of the frond, tapering to the apex and base. 

 Pinnae oblong-ovate, spreading. Pinnules roundish, tapering to 

 the base. 



Margins of the frond deeply notched with from two to seven 

 angular mucronate teeth. Caudex short, upright, tufted and 

 scaly. Stipes slender, dark brown near the base, higher up, 

 the frond green; one-third of the length of the frond. Rachis 

 green. A flexuous mid vein, with alternate simple veins from it. 



Sori small, two to four on each pinnule, covering the whole 

 under side of the frond; confluent; indusium white. 



Length of frond from four to six inches; colour dark green. 



A hardy, or half-hardy species, easily grown under pot 

 culture, requiring a porous peaty soil, with plenty of drainage 

 and a mixture of sand and loam.
