northward of the town and river, that is, in the West 

 HigUand province ; especially as the three localities ex- 

 pressly mentioned appear to be all within the West 

 Lowland province. I have seen this grass at Callander 

 and Killin, quite on the western side of the East Highland 

 province.

Native. Agrestal. The authorities for the alleged

 may be traced through the New Botanist's Guide. The 

 four counties above mentioned can alone be considered 

 certain habitats for this species. It is confidently referred 

 by Dr. Bromfield to the Atlantic type, as one " than which 

 few species are more characteristic of the occidental floi'a" 

 (Phji^ologist, iii. 1112). This is not strictly correct 

 though nearly so, because the species ranges along the 

 southern coast, from Cornwall eastward to Hants, but 

 does not pass up the western coast, so far as is yet cer- 

 tainly ascertained, either to Wales or to the south side of
