Interruptuai, Moore. (Plate XLV. — A.)— I received this 

 form from Messrs. Stansficid, of the Vale Nursery, Todmorden. 

 It differs in its interrupted character, the pinntie being very- 

 various in size and shape. Some elongate-triangular, others 

 elongate-ovate, one pinna being four times the size of the next 

 pinna, and so on. My thanks are due to Messrs. Stansfield 

 for a frond. 



Ramosum, Wollaston. (Plate XLV.— B.)— Found in 1850, 

 in Dorsetshire, by Mr. G. B. Wollaston, and very distinct. A 

 dwarf Fern, with broad short pinnrc, the basal ones triangular, 

 and as broad as they are long, towards the apex narrower, 

 and slightly elongated, or elongate-triangular. Pinnse cuncate at 

 their base, with an irregular undulate or broadly crenate 

 margin; the ultimate pinna branching either in the "rachis or 

 stipes, and becoming twin-fronded. Sori abundant and con- 

 spicuous. My thanks are due to Messrs. Stansfield for fronds.
