Native. Eupestral. The name "P. glauca" having 

 been occasionally applied to a glaucous state of P. pra- 

 tensis, found in the south of England and jDrobably else- 

 where, might give rise to erroneous ideas of the area and 

 range of the mountain plant equally so designated. Re- 

 ference may be made to the preceding species, P. Balfourii, 

 for remarks on this present one. Though treated apart 

 here, it will be necessary to sink the one under the other 

 in an after part of this work, where tabular or statistical 

 results will be rendered, and in wliich fragmentary distri- 

 bution would be found liighly inconvenient.
