VAIUKTIES OF FERNS IN THIS BRISTOL DTSTRIGT. 217 



Var. Coniutiim (Loijmcr), an uiii(;[UG fom, found some 

 3'eai-s aiiice on a wall at ]jong Ashton, by Mr. A. 

 Leipuer, and described by liim as being undulate 

 with cronato margins, and witJi the last half-inch 

 of the midrib leaving the plane of the frond and 

 proj'ecting horn-like from its upper surface. 

 Var. Peraferons. This remarkable form, in which the 

 frond is truncate, terminating in a distinct jiouch 

 at the back of the frond, while the midrib is pro- 

 longed for an inch or so, like a horn, was found by 

 myself in considerable qunntitles in a wood at 

 I'ortishead, and is no doubt still to be found there ; 

 four plants of the same variety were also found by 

 me at Westbury-on-Trym. 



Var. Undulatum. A good form of this variety was 

 found by Mr. G-. B. WoUaston, near Pill, about ten 

 years ago. 



Var. Fissum. An unusually good form was found by 

 mo in Leigh Woods about twelve years ago ; also 

 a vei-y good form, about the same time, at W^est- 

 bury-on-Trym. 



Var. Variabiio. Unusually good forms of this very ]>ecn- 

 liar variety have been found at Wostbury-on-Trym. 



Var. Laciniatum, more than once in the same neighbour- 

 hood. 



Var. Multifidum. Many fine forms of this have been 

 found at Westbury-on-Trym, Portishead, and other 

 places. 



Var. Marginatum. A good form of this was found by 

 mo in company with Mr. Wollaston near Pensford. 



Var. Submarginatum. This has been found in some 

 quantity in a wood near Kingswoston and in other
