Native. Sylvestral, Ericetal. Whilst P. rotundifolia 

 has been made to appear more frequent than the reality, 

 the present one has been likely brought lower in the scale 

 of its frequency, through several of its habitats ha\"ing been 

 assigned to other species. P. rotundifolia is said to have 

 occun-ed very locally in North Devon and South Kent, 

 and P. secunda in Sussex ; but P. minor appears to be the 

 more likely species. Specimens of this present species 

 are in my herbaiium from the counties of Gloucester (Mr. 

 Stephens, Bot. Soc. London), Oxford (Dr. Ajres, Bot. 

 Soc. London), and Sm-rey (Mr. John Ellis) ; |and also from 

 various counties more northerly than those three. I pos- 

 sess no note of seeing P. minor at any elevation greater 

 than 500 yai'ds ; but think that I must have seen it to the 

 inferarctic zone, at least.
