2. A. BicoLOR, Elirli. On moss and dead grass, at Lowrey's Knowes near 

 Dowlaw, in dense entangled short bushy tufts, not half an inch in height, of a 

 grey green tint above, but black at the base. Though dwarfed in its propor- 

 tions, it has the habit of the more luxuriant state. A. Chalybeiformis grows 

 beside it, and in one instance through it, but retains its own characteristics. 

 The height of the locality will be about 700 feet above the sea. On Ben Lawers 

 1000 feet is near its place of growth. It is remarkable to find it isolated here, 

 and occupying not a square yard of surface.
