CALAMAGB6STIS (Greek for reed grass}. Gra- 

 in in., i. Heed Bent-grass. A genus of perennial grasses 

 with rniiiniig rootstocks. Very similar to Agrostis, but 

 spikclcfs usually larger. Can be distinguished from it 

 by the tuft of long hairs at the base of the fl. -glume, 

 and the flowering axis continued beyond the palet. 

 Spikelets 1-flowered (rarely an aborted or second flower 

 present). Glumes 3, the first two nearly equal and 

 empty, the third, or fl. -glume, awned on the back, usu- 

 ally below the middle. Species about 120, very widely 

 distributed over the world in the temperate aiid arctic 

 zones and on the high mountains of the tropics. For 

 V. brei-ii)ilis, see Calamovilfa. 



Canadensis, Beauv. Blue-joint Grass. Very com- 

 mon in the northern and northwestern states, usually 

 growing in moist meadows and swales. Under such 

 conditions it yields a large amount of indifferent hay, 

 which is used in some places. It is not used for horti- 

 cultural purposes. This species grows 3-5 ft., and has 

 flat, glaucous-blue Ivs. : panicle oblong, becoming open • 

 upper glume weak-awned near the middle. 



Btricta, Beauv. (C. negUcta, Gtertn.). Pony Grass. 

 A rather slender, erect perennial, with narrow leaves 

 and a contracted, densely-flowered panicle, 3-C in. long: 

 fl. -glume about % as long as the second empty glume, 

 and nearly twice the length of the basal hairs ; awn 

 bent, exceeding the glume. Northern U.S. -A varie- 

 gated form has been brought into cultivation for orna- 

 mental purposes. „ „ t-

CALAMlNTHA (Old Greek name, meaning beautiful 

 mini]. Lithii'ilit . Various species of herbs or very small 

 shrubs. 2 or :i id them occasionally grown in borders for 

 their lis. and aroTiiMtii' fi-;iL'v:»ncc. Calyx 2-lipped, ob- 

 long or tubular: '-im 

 erally exceeding tin 

 larged ; stamens 1:1 

 whorls, which are ii^i 

 spike. Plants mostly 



,'ht tube, and gen- 

 >at commonly en- 

 npper lip : fls. in 

 a long interrupted 

 gions, and of easy 

 jlture. The cult, kinds are perennial, more or less 

 hairy, mint-like herbs, 1-3 ft. high. 



grandiil6ra, Mcench. Lvs. ovate, serrated : stems de- 

 cumbent, branching from the base : fls. in axillary 

 whorls, quite large, \% in. long, with a straight tube ; 

 upper lip flattened, purple ; June-July ; h. 9-12 in 

 Europe ; this and C. iilp)tia. Lam., which is smaller in 

 all its parts, are thf twn hi«t sppcies for garden use. 

 C. officinAlis, Mcen.'li , th.- .oniini.ti Calamint of Eu., is 

 sometimes seen in tjar.l. ii<, iLinuan old domestic medi- 

 cinal plant. It has l.m:.'. as., inliiig branches, ovate 

 crenate-serrate Its., and luw-dd. cymes : 1-3 ft.

 CALAMOViLFA (Calamos, reed, and Vilfa, a kind of 

 grass). Oramlnece. A genus recently separated from 

 Calamagrostis. Distinguished from it only in that the 

 flowering axis is not produced beyond the flower. Tall 

 grasses, with stout, horizontal lvs. and paniculate in- 

 florescence. Spikelets 1-fiowered, with a ring of hairs 

 at the base of fl.-iflume. Three known species, natives 

 of till- t.ni|ii'ratc and sul)trn]ntal rt-gions of N. America, 

 brevipilis. Hark. u'alaiHa.ir.ixlin brevipllis. Gray).
