On the loftiest mountains of Scotland, but rare. 



On the rocky parts of the mountains of Clova, Angusshire. G. Don. 



Perennial. July. 



Root fibrous. Stems tufted, from 1 to 2 feet high, leafy, some- 

 times purplish in the naked part. Leaves flat, pointed, rough- 

 edged ; the sheaths of the upper ones a little swelling. Stipula 

 short and blunt. Panicle close, from 1 to 3 inches long, much 

 thicker than the last. Calyx-glumes exactly lanceolate, not 

 abrupt, with sharp, rigid, often inflexed points ; their keels 

 strongly fringed ; the ribs and sides rough, with fine white hairs. 

 Cor. essentially different from the last, being of the texture of 

 the calyx, and almost as long, fringed j the outer glume with 

 5 ribs 3 inner cloven at the summit. 



6. Ph. arenarium. Sea CatVtail-grass. 



Spike slightly panicled, ovate-lanceolate, obtuse. Calyx- 

 glumes lanceolate, fringed, thrice the length of the abrupt, 

 notched, corolla.

On the sandy sea coast frequent ; also on Swaffham and New-

Annual. May. 



Root of many long, simple, partly downy, fibres. Stems several, 

 except in a starved state, 3 — 6 inches high j leafy below ; naked 

 and purplish above. Upper leaf very short, with a long, rather 

 swelling, sheath. Stipula lanceolate. Spike thick and short, 

 variegated with green and white, narrow at the base. Inner 

 margin of the calyx often a little abrupt. The very short, ribbed, 

 abrupt, crenate outer glume of the corolla characterizes this 

 very distinct species. The whole plant is somewhat glaucous, 

 and after flowering remains long bleached, and often blown 

 about, on the sand. Professor Hooker's reference to Scheuchzer 

 should be 63, not 68, and belongs to Plukenet's synonym.
