SCOLOPENDRIUM VULGARE, Var. Jugosum. 



Moore. 



PLATE XXIV. 



Scolopendrium — Hart'a-tongue. Vulgare — CommoQ. 



Jugosum — Full of ridges. 



This singular Fern was found in Guernsey by Mr. James, 

 of Vauvert, and Mr. Jackson. 



It differs in having the soriferous veins thickened, and thus 

 producing on the upper surface of the fronds a series of ridges, 

 or leafy sorus-like excrescences. 



The length is from twelve to fourteen inches. 



There are several forms in cultivation. 



For the specimen illustrated I am indebted to Mr. C. 

 Monkman, of Malton.
