sect.S. 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 

 srtem. 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. I 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.
