286 SCOLOPENDRIUM VULGARE. 



Fig. GT5.) — An interesting and desirable variety raised by Mr. 

 Clapbam, of Scarborough, a gentleman well known for the 

 many remarkable varieties he has added to our British Ferns. 

 Fovmd also at Oldstead, Yorkshire, by Mr. C. Monkman. A 

 very singular dej^auperated form. Sinuately lobed or irregularly 

 contracted or laciniated. Length eighteen inches. Four or 

 five inches below the apex branching, and each branch an 

 inch below the apex again branched. Sometimes nearly the 

 whole of the frond is depauperate, at others one side only of 

 the costa; but everywhere very irregular. A remarkable form. 

 My thanks are due to Mr. Clapham for a frond, 



SupRALiNEATO-MULTiFiDUM, Moore. (Fig. 676.) — Length six 

 inches, width one inch. Margin irregularly cut, supralineate 

 near the costa, the apex multifid, their apices narrowed. The
