by Lowe and Clouston ; yet scarcely admissable as a spe- 

 cies indigenous in those islands, until confirmed by other 

 observers. The Lake province, also, requires coiToboration 

 by a better authority, although likely enough in itself.

Native. Rupestral and Glareal. A thinly scattered 

 species, the distribution of which is neither eastern nor 

 western, northern nor southern, local nor mountain, to such 

 a degree as to throw it into any one of the types of distri- 

 bution, specially distinguished from the British type ; and 

 yet it is too local to come fairlj^ under the last more general 

 type. Mr. Lees finds it at about 1000 feet of elevation on 

 the Malvem Hills. Though apparently restricted to the 

 eastern provinces in Scotland, there is no such limitation 

 to its area in England. I feel uncertain whether my 

 Cumberland specimens should be refeiTed to P. verna or 

 to P. alpestris.
