repoi-ted to have been found in Sutherland, on the summit 

 of Fonniven, and also on the ridge leading to the top of 

 Ben More, Ass3'nt, ascending from Inchnadamf. It is 

 fui-ther said to have been seen on the Clova moimtains, 

 in 1824, by "Hooker, Greville, BurchHl, and Drummond:" 

 is this correct ? I do not know the altitude of Fonniven, 

 or that of the " ridge " of Ben More ; perhaps 1000 yai-ds 

 may be too low.

Native. Ericetal, Rupestral, &c. Frequent on the 

 Highland mountains, but very local in England and 

 Wales. This species and L. arcuata grow on gi'avelly de- 

 tritus, and in so far the term " glareal " might seem best 

 to express theii- situations of growth. But that term 

 having been applied to the plants of dry gi-avelly and 

 sandy places, is not well adapted to express the natural 

 situations of those plants that grow on the almost con- 

 stantly humid gi-avel of the arctic region.
