 sect. 8. t. 9.f. 6. 



On barren mountainous moors, frequent. On turfy boggy heaths 

 in the south of England, more rarely. 



Perennial. March, April. 



Root slightly creeping. Stems tufted, jointed, smooth, finally 

 12 — 15 inches high, with 1 or 2 inflated, strongly reticulated 

 sheaths in the lower part, and below them several erect, slender, 

 triangular, striated, sharp-pointed leaves, nearly as tall as the 

 stem. Spike silvery grey when in flower, with long-pointed, 

 thin, single-ribbed scales, and yellow prominent anthers; when 

 in seed very conspicuous, in May and June, from its copious, 

 long, white, soft and smooth hairs, by means of which the little 

 triangular seeds are finally carried away by the wind. 



Ray reports that sheep are very fond of this plant. 1 have found 

 the leaves fed down early in the spring, before the stems run to 

 seed. 



2. E. capitatum. Round-headed Cotton-grass. 

 Stem entirely round, with a swelling sheath. Spike roundish. 



Glumes membranous.

Root extensively creeping. Stem about half as high as the fore- 

 going, but of a stouter habit, and cylindrical throughout. Leaves 

 thicker, and much shorter. Glumes smaller, and not quite so 

 thin and delicate j the outer one with many ribs. Hairs of the 

 seed much shorter than the former. 



3. E. alpinum. Alpine Cotton-grass. 



Stem triangular, naked above the leaves, which are shorter 

 than their sheaths. Spike oblong-ovate. Glumes firm, 

 strongly keeled.
