Native. Pascual, Eupestral. Formerly included with 

 P. Sanguisorba, and only very recently distinguished from 

 the latter in England. It has occurred in Hants (Rev. W. 

 W. Spicer), Sui-rey and Essex (Mr. G. S. Gibson!), Suffolk 

 (uncertainly native, Mr. W. Matthews), Cambridge (Mr. G. 

 S. Gibson), Warwick (Mr. Thomas Kirk!), Hereford (Mr. 

 W. H. Purchas) ; and it may be expected in various other 

 intermediate or adjacent counties ; although the smaller 

 P. Sanguisorba is probably much the more frequent and 

 more widely distributed species or variety.
