SCOLOPENDEIUM VULGAKE, Var. Cbistatdm. 



Moore. 



PLATE XXI. B. 



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



Cristatum — Crested. 



A VERY handsome variety of the Scolopendrium vulgare. 



The fronds are multifid, very much divided, and forming 

 large tasseled heads; the divisions at the apex angular. 



Length of frond six or eight inches. 



There are several sub-forms of this Fern in cultivation. 



For a description of the normal form of Scolopendrium 

 vulgare see page 155, vol. v, of my "Natural History of British 

 and Exotic Ferns," and for woodcuts of the varieties laceratum, 

 multiforme, and acrocladon, see page 158 of the same book. 



For fronds my thanks are due to Mr. Wollaston, of Chisel- 

 hurst, and Mr. Stansfield, of Todmorden. 



The illustration is from a plant in my own collection.
