or only in one of them, I cannot clearly make out by the 

 descriptions. There is one other distant station on re- 

 cord ; namely, Woolston Moss, near Warrington (Mr. W. 

 Christy, in Mag. Nat. Hist. vi. 5G) ; but this out-Mug and 

 low-lying station may be an error. The indications of 

 altitude, zone, and temperature, must be taken as partial 

 approximations only; their actual range being perhaps 

 more extended.

Native. Sylvestral, &c. The localities of this fern, 

 the L. spinosa of Newman's History, have been so inextri- 

 cably confused with those of Lastrea dilatata, the L. 

 multiflora of Newman, that almost all of them may be 

 said to require verification ; unless it be those which have 

 been reported within the last half dozen years, and by 

 botanists who had carefvilly studied the distinctive cha- 

 racters first clearly given by Mr. Newman, and subse- 

 quently by Mr. Babington. I possess specimens of L. 

 spinulosa from Surrey, Middlesex, Essex, Norfolk, War- 

 wick, Chester, and Cumberland. The authorities on which 

 I give the area above, are the following : — Peninsula (Rev.
