SCOLOPENDRIUM YULGARE, 

 Var. Marginato-irregulaee. 



Clapham. 



PLATE XXXIX. B 



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



Marginato-irregulare — Irregular-margined. 



An interesting and desirable variety of our English Scolopen- 

 drium vulgare, raised by Mr. Clapham, of Scarborough, a 

 gentleman well known for the many remarkable varieties he 

 has added to our British Ferns. 



The present species is most variable, the fronds being irreg- 

 ularly margined, and their apices multifid. 



So variable is the form of the fronds of this Fern, that no 

 two are alike. 



Length of frond nine to twehe inches. 



For the fronds illustrated I am indebted to Mr. Clapham, of 

 Scarborough.
