A CONTRIBUTION TOWARDS A FLORA OF BRECONSHIRE. 41 



tracts of old red sandstone to be found in the subprovince of South- 

 east Wales. 



I am greatly indebted to the Eev. A. Ley, who has most kindly 

 allowed me to incorporate his extended observations with my own, 

 and has communicated much valuable information relating to the 

 botany of the county. My grateful acknowledgments are also due 

 to Mr. J. G. Baker, F.E.S., the Eev. W. W. Newbould, F.L.S., and 

 the Eev. W. Moyle Eogers, F.L.S., for kind assistance in iden- 

 tifying some critical plants. I am responsible for all the plants 

 and stations against which no authority is attached. The nomen- 

 clature of the 7tli edition of the London Catalogue has been 

 adopted in this paper. Those plants which are new records for the 

 county, in tlie sense of not having been recorded either in ' Topo- 

 graphical Botany,' or in either of the lists before alluded to, are 

 distinguished by the prefixed asterisk ; C stands for common, F for 

 frequent.
