Perennial. June, July. 



Root creeping, throwing up a row of crowded stems, destitute of 

 joints, 4 — 6 inches high, with 3 rough angles. Leaves few, very 

 short, channelled, rough-edged, with long, striated, smooth 

 sheaths. Spike erect, very small, of a few ovate, rusty, chaft'y 

 glumes, each with a strong, green keel, and quite unlike the 

 grey, filmy, tapering scales of the 2 preceding species. Hairs 

 white and shining, few in each spike, erect, not concealing the 

 glumes. 



The late Mr. G. Don justly pointed out to us that the shoot with 

 long leaves, annexed to the figure in Engl. Bot., belongs to 

 Carex dioica, a plant frequently intermixed with this Eriophorum, 



** Spikes several. 



4. Yt. polystacMon. Broad-leaved Cotton-grass. 



Stem round. Leaves flat, lanceolate, with a triangular point. 

 Stalks of the spikes smooth. Hairs thrice the length of 

 the spike.
