SCOLOPENDRIUM VULGARE, Var. Submarginatum. 



Moore. 



PLATE XXIV. — A. 



Scolopendrium — Hart's-tongue. Vulgare — Common. 



Submarginatum — Partially margined. 



An interesting variety, found in several places in Great 

 Britain and Guernsey. 



The fronds, which vary, are frequently bifurcate or ramose, 

 partially margined, the margin either crenato-lobate, lobate, 

 narrowed and trebly dentate, or truncate and obliquely cornute. 



It has a thin skin-like irregular line just beneath the jagged 

 margin of the frond, which, however, is not always continuous. 



The sori are bold and lengthy within the skin-like line, 

 having also a short sori outside this line. 



Length of frond from eighteen to twenty-four inches. 



The frond from which the illustration is taken was found 

 at Oldstead, Yorkshire, and kindly communicated by Mr. C 

 Monkman, of Malton.
