On lofty mountains. 



Common in the Highlands of Scotland. Hooker. On Corbie Craig 

 near the river Esk, 5 miles from Forfar. Mr. G. Don. The late 

 Mr. J. T. Mackay sent it from the place last mentioned^ as well 

 as from Ben Lawers^ and other mountains of Breadalbane^ chiefly 

 in a viviparous state. 



Perennial. July, August. 



Root fibrous, tufted, not creeping. Stem 4 — 12 inches high, erect, 

 thelower joint only being sometimes bent; leafy below; naked, 

 round, striated, and smooth at the top, with frequently a tinge 

 of pui-ple. Lec/iJes linear, rather broad,fiat, many-ribbed, bluntisli 

 with a small point, rough at the edges and sometimes on the 

 upper side ; a little glaucous beneath : radkal ones numerous, 

 tufted, some of them narrower, spreading, with smooth lax 

 sheaths, and short blunt stipulas ; those of the stem having much 

 longer sheaths, each crovv'ned with a lanceolate, often torn, sti- 

 pula. Panicle spreading, short, somewliat ovate, or triangular, 

 its branches angular, wavy, nearly smooth, mostly in pairs, re- 

 peatedly subdivided. Spikelets so broad as to be often almost 

 heart-shaped, usually of A florets, in cultivated specimens of 6, I 

 have never seen 9 or 1 1 , as observed by Schrader. Glumes con- 

 cave, keeled, moderately compressed, green at the back, purple 

 at the sides, membranous and white at the edges, those of the 

 calyx 3-ribbed, much resembling the outer valve of the cor., ex- 

 cept that the lower half of the latter is silky, especially the keel, 

 and the base of each floret bears several longish straight hairs, 

 but the complicated web is wanting; inner valve finely fringed 

 at the ribs. Stigmas feathery, but according to Mr. Sowerby's 

 observation, slender, and I cannot ascertain whether they are 

 compound or not. The whole panicle often consists of buds in- 

 stead of real florets, particularly in wet seasons. There is also 

 a densely tufted variety, represented in Mr. Knapp's <• 1 17. 



3. P. laa^a. Wavy Meadow-grass. 



Panicle drooping, loosely spreading, zigzag. Spikelets ovate, 

 three-flowered. Florets connected by a web. Stipulas 

 all lanceolate.
