90 CALAMAGROSTIS. [CLASS in. ORDER n. 



Leaves long, narrow, the edges incurved, rough on the under side, the 

 upper more or less scattered with hairs. Sheaths long, finely striated, 

 close, roughish on some plants. Ligula oblong, obtuse, torn, and ge- 

 nerally decurrent. Inflorescence an erect spreading panicle, from three 

 to six inches long; its branches slender, rough. Spikelets not so 

 crowded as in the last, more open and spreading every way. Glumes 

 lanceolate, a shining purple, green at the base, keel smooth ; the whole 

 valves, particularly in the upper part of the panicle, are hairy, while 

 those in the lower part are quite smooth. Glumelles thin, membra- 

 nous, unequal ; external valve the largest, about half as long as the 

 glumes, notched or torn at the extremity, with two or four lateral ribs 

 and a keel, terminating in a very short rough awn ; inner valve notched 

 at the extremity, surrounded with hairs at the base, which are shorter 

 than the glumes. 



Habitat. In ; moist woods and fenny situations. Lincolnshire, Cam- 

 bridgeshire, Norfolk, &c. Not uncommon. 



Perennial ; flowering in June and July. 



3. C. stric'ta, Lindl. (Fig. 114.) narrow Small-reed. Panicle erect ; 



glumes broadly lanceolate acute, rough on the keel ; about the 



same length as the glumelles ; awn not extending beyond them ; 



hairs about half as long ; inner value with an abortive hairy floret 



at its base.

 Root with creeping underground stems. Stem about two feet high ; 

 slender, rough, with fine erect teeth, especially in the upper part ; 

 striated, branched, and leafy below ; the lower joints putting out nu- 

 merous fibrous roots. Leaves long, narrow, finely pointed ; striated 

 rough, more so on the upper than the lower surface. Sheaths close, 

 finely striated, somewhat rough. Ligula short, abrupt,'notched or torn, 

 those of the upper leaves longest. Inflorescence an erect close panicle, 

 except when in flower ; it is from two to four inches long, the branches 

 partly whorled very rough. Glumes a light brown colour, darker at the 

 base, smooth or finely hairy, broadly lanceolate, frequently torn at the 

 extremity ; keel not very prominent and more or less rough, the external 

 valve sometimes with two lateral ribs. Glumelles about the same 

 length as the glumes, membranous, brownish, surrounded at their base 

 with a tuft of glossy hairs, scarce half as long as the valve when in 

 flower, but becoming longer when in seed ; the external valve bifid at 

 the extremity jagged, the edges inflexed from the two lateral roughish 

 ribs, a roughish dorsal awn arises from below the middle and extends 

 a little beyond the extremity ; the inner valve shorter than the outer, 

 entire or slightly jagged at the extremity, with a solitary marginal rib 

 on each side, and at the back is a channel, in which is embedded an 

 abortive hairy awn-like valve about half its length. Styles distinct 

 erect. Stigmas feathery.
