86. GRAMINA. 171

A. A. regions. Inferagrarian — Midarctic zones.

Ascends to 800 yards, or upwards, in East Highlands. 



Kange of mean annual temperature 52 — 39. 



Native. Pascual, Ericetal, &c. An abundant grass, 

 and probably rising higher than 800 yards, on the High- 

 land mountains. Not unlikely, the names of these three 

 species, — canina, vulgaris, alba, — are frequently misap- 

 plied or crossed ; their mutual resemblances, their varia- 

 bility of habit and colour, and the small size of their 

 flowers, all conducing to confusion or errors of name.
