feet long, by | to i inch broad, with 3 or 4 broad ribs on each side 
of the midrib clothed with minute asperities pointing forward; the 
marginal ribs with larger prickles, also pointing towards the apex of 
the leaf. Stem 2 to 4 feet high, with its leaves much shorter than the 
radical ones, but otherwise resembling them, flat, bat as well as the 
radical ones becoming involute when dry. Panicle 6 to 15 inches 
long, by about half as broad. Spikelets very numerous, I inch long. 
Var. 3 has the stems 15 inches to 2 feet high; the radical leaves 
2 to 6 inches long, and erect, not arching as in var. a ; the panicle 
more compact, 2 to 4 inches long; the spikelets a little larger, and 
much more deeply coloured. 
Var. y is similar to var. i3 in its short leaves and low stems. Panicle 
4 to 8 inches long, almost always viviparous. Spikelets nearly I inch

This grass, according to Parnell. has a most unsightly appearance in meadow-pastures 
termed by farmers rough cups or hossacks, and are difficult to get rid of. From the 
It is a sure indication, wherever found on the farm, that the land wants under- 
draining, without which no cutting it out will destroy it. But the efficiency of 
drainage, where it occurs, is seen by its dying away and scattering the fields with its 
turned up rough bunches of dried leaves. Its flowering-panicles are very beautiful.

On rocky debris on high mountains. Rare. Most plentiful on the 
Braemar Mountains, and on Loch-na-gar. I have specimens also from 
Ben Voirhch, and it is said to have occurred in many other places in 
the Highlands, but it has been so confounded with the var. y of A.

by specimens.
