In groves and woods. 



Most plentiful in the north of England, where it is very common j 

 as also in woods on a chalky soil in the south. 



Perennial. June, July. 



Hoot fibrous, scarcely creeping. Whole plant very slender and 

 delicate, 1| or 2 feet high. Stems several, erect, slightly com- 

 pressed, smooth, striated, leafy, with 4 or 5 joints. Leaves al- 

 most all on the stem, grass-green, narrow, flat, with 3 principal 

 ribs and many intermediate ones ; more or less rough, espe- 

 cially the mid-rib and edges ; tapering to a fine slender point ; 

 the lowermost smooth at the back. Sheaths hardly so long as 

 the leaves, compressed, nearly smooth. Stipula very short in 

 ail the leaves, and inclosed within the sheath, but visibly notched 

 along the margin . Panicle erect, or slightly drooping to one side, 

 very slender, with numerous, half-whorled, angular, rough, wavy, 

 compound branches. Spikelets erect, pale green and white, with 

 a purplish tinge ; their general surface shining, and nearly 

 smooth. Cal. of 2 unequal, lanceolate, taper-pointed, almost 

 awned valves, each with 3 ribs ; the keel, or central rib, rough ; 

 the margin of the larger, or innermost, much dilated and mem- 

 branous. Florets 2 or 3, rarely 4. Outer valve of the cor. lan- 

 ceolate, acute, with 5 ribs, of which the 2 marginal ones and 

 the keel are finely silky at their lower part, the 2 intermediate 

 ones smooth, and not very conspicuous, unless the glume be 

 held against the light j inner valve narrow, rough-edged, cloven 

 at the point. The base of each Jloret is sometimes, not always, 

 hairy, but there is no complicated web. Stigmas large and tufted. 

 Mr. Sowerby found the nectary of 2 acute cloven scales. 



j3 is of a firmer habit, less slender in every part, with a more dense 

 panicle, and sometimes more numerous^orefc. An original spe- 

 cimen proves it Mr. Hudson's P. angustifolia, of which he sub- 

 sequently made nemoralis a subordinate variety. But it is not
