(A. alpi'na. Panicle rather dense and upright. Florets the length of 
the calyx, acute; one of them on a smooth stalk: awn short, 
from near the top of the outer valve. Leaves involute awl- 
shaped, with smooth sheaths. 
E. Bot. 2102. 
In habit much resembling the last, but only half as tall. Radical leaves 
become awl-shaped: the back, though ribbed, is smooth. Panicle 
branches fewer and less spreading than in A, ccespitosa. Flowers decidedly 
larger, greener, less numerous; in mountainous situations often vivipa¬ 
rous. Partial stalk, elevating one floret, quite smooth, not downy. Sm. 
Wahlenberg considers this to be the real A. alpina of Linnaeus, in 
which suggestion Hooker and Smith concur, though the fact remains 
somewhat problematical.

About a foot high when young, taller when old. Panicle fine glossy purple, 
from two to three inches long, and half an inch broad; branches flexuose 
and nearly upright in its young state, the florets mostly pointing one way ; 
as it approaches maturity the purple fades, the branches expand so that 
the panicle then measures one or one inch and a half across. Blossom 
woolly at the base. A wn geniculate, half as long again as the blossom.

* It is very apt to grow in tufts, and occasions irregularities in the surface of meadows. 
The leaves of this grass are the roughest and coarsest of all the grasses growing in pas¬ 
ture or meadow grounds, and therefore cattle will seldom touch them, unless forced by 
hunger. It produces an abundant quantity of leaves, and few flowering straws ; has 
a very disagreeable appearance in meadows, and often occupies much ground which 
might be made to produce better grasses. To get rid of it, the land should first be 
drained, and then the tufts of this noxious weed should be pared up and burnt. The 
ashes will be a good manure. Called by the common people Hassocks, Rough Caps , 
Bulls’ Faces. Rev. G. Swayrie.
