Root perennial. Culm about a foot and a half high, leafy 

 soboliferous at the base. Leaves linear, very narrow, almost 

 as tall as the culm, glaucous, keeled or compressed. Stipule 

 truncate very short. Sheaths smooth, compressed and carin- 

 ate, often standing off from the culm, and never surrounding 

 it. Panicle terminal, purple, sparingly branched ; brandies 

 erect and virgate. Calyx : valves much shorter than the co- 

 rolla, lanceolate; inner valve 1 -nerved, serrulata on the keel, 

 notched at the apex ; sometimes it is mucronate and rather 

 obtuse, or denticulate. Corolla : valves smooth, lanceolate, 

 and often split down to the base. Stamina. Styles 2. Stig- 

 mas purple.

This grass is covered with a viscid acid substance, which 

 deserves to be investigated. It strongly reddens vegetable 

 blues, and has a very peculiar taste. It appears to be a se- 

 cretion from the plant, and can be observed, appearing like 

 dew upon the hairs which cover it.

Culm about a foot and a half high. Glumes larger than in 

 any other species in this neighbourhood. It is nearly allied 

 to P. latifolium.

 This species resembles P. nitidum, but it differs from it in 

 having a smaller panicle and flowers ; in the sheaths being 

 ciliated and the leaves broader.
