and the longer portion descending, and thus clothing the whole 

 of the rachis. The ajiices of the pinnae are more flat than

 Ivery, of Dorking, for fronds. 



Interruptum. — Mr. Elworthy's form of Interruptum, from 

 which I believe JNlr. Moore took his name, was found near 

 Nettlecombe. Fronds twenty-six inches long, and seven inches 

 wide in the broadest part. A very lax Fern, Pinnse distant, 

 about sixteen pairs, sub-opposite below, alternate above; singu- 

 larly various in size and form. Pinnules nearly all depauperate,

 anterior basal pinnule much the longest. Sometimes the upper 

 half of the frond is contracted to an inch in width, for at least 

 six inches in length. I am indebted to ^Ir. Elworthy for fronds. 

 An illustration is unnecessary.
