BRITISH FLORA 



broadly elliptical, 3-angled, pale, with a long beak. 

 The plant is 1-2 ft. high, flowering in May and 

 June, and is a herbaceous perennial. 



Bottle-fruited Sedge (Carex ampullacea, Good. 

 = C. inflata, Huds. = C. rostrata, Stokes). The 

 habitat of this plant is wet bogs and marshes. 

 The plant has the sedge habit. The rootstock is 

 tufted and creeping. The stems are 3-angled, 

 smooth, the angles blunt. The leaves are chan- 

 nelled, bluish-green, the margins rolled back. The 

 fertile spikelets are pale, stout, cylindrical, 2-4 

 distant, erect, stalked or stalkless, inclined or 

 spreading, dense. The male spikelets are 2-3, 

 slender, with sometimes female at the base. The 

 bracts are leaflike without a sheath, longer than 

 the stem. The glumes are lance-shaped, inversely 

 egg-shaped, with membranous tip. The fruit is 

 spreading, egg-shaped, rounded, suddenly nar- 

 rowed into a long, slender beak, pale-yellowish- 

 green, swollen, ribbed, shining, as broad as long, 

 3-sided, horizontal or bent-down when ripe, nar- 

 rowed into a long beak. The nut is inversely egg- 

 shaped, triangular, yellow. The plant is 1-2 ft. 

 high, flowering in May and June, and is a herb- 

 aceous perennial. 



Russet Sedge (Carex saxatitis, L. = C. putta, 

 Good.). The habitat of this plant is damp places 

 on Scotch mountains. The plant has the sedge 

 habit. The stems are short. There is i male 

 spikelet or 2. The fertile spikelets are 1-3, egg- 

 shaped, very dark, round to egg-shaped, the lower 

 stalked, with bracts without sheaths, erect, black 

 or dark -brown. The glumes are blunt, dark- 

 purple, with white tips, the midrib dark-purple. 

 The fruit is egg-shaped, with faint (or no) ribs, 

 inflated, dark-purple, paler below, longer than the 

 glumes, stalked. The beak is short, notched. The 

 nut is round, blunt-pointed. There are 2 stigmas. 

 The plant is 4-10 in. high, flowering in May and

ORDER GRAMINACE^E 



Deyenxia neglectct, Kunth. The habitat of this 

 grass is marshes and bogs. The plant has the 

 grass habit. The stems are erect, slender, smooth, 

 polished. The leaves are broad, short, flat, the 

 lower on the barren shoots slender, narrower, the 

 margins convolute, nearly smooth. The ligule is 

 short, the uppermost blunt. The panicle is nar- 

 row, erect, close, pale-purple and green. The 



glumes are lance-shaped, with a rough keel, 

 one 3-ribbed. The empty glumes are oblong to 

 lance-shaped, longer than the flowering glume, 

 the lower long-pointed, the upper notched, acute, 

 twice as long as the hairs, the awn straight, from 

 below the middle of the flowering glume. The 

 plant is 1-2 ft. high, flowering in June and July, 

 and is a herbaceous perennial. 



Deyeuxia strigosa, Kunth. This plant has the 

 grass habit. It is tufted. The stem is erect. The 

 leaves are slender. The upper ligule is long. The 

 panicle is close. The glumes are lance-shaped, 

 folded at the tip, longer than in the last, with a 

 long narrow point, rough on the back, with 1-2 

 lateral ribs longer than the palea, notched, the 

 lower with an awn of equal length, attached below 

 the middle, or near the base, with very unequal 

 hairs, not so long as the palea. The young spike- 

 lets are purplish-tinged. The plant is \\-z ft. high, 

 flowering in July, and is a herbaceous perennial. 



Cutgrass (Leersia oryzoides, Sw.). The habitat 

 of this species is stream-sides, marshy districts, 

 wet meadows, and watery places. The plant has 

 the grass habit. The root is creeping. The stems 

 are prostrate below, smooth, shining, leafy, softly 

 hairy at the nodes. The leaves are broad, rough 

 at the edge, the uppermost horizontal when the 

 plant is in flower, bluish-green. The sheaths are 

 flattened, nearly smooth. The ligule is blunt, 

 torn. The panicle is effuse, spreading, with wavy 

 branches, light-green, enclosed in sheath of upper- 

 most leaf, loose, few -flowered, branches half- 

 whorled, hair-like, wavy. There are imperfect 

 ovaries in the upper part, fertile ovaries in the 

 lower enclosed part. The spikelets are half-oval, 

 with a keel fringed with hairs, with 3 stamens, 

 rigid, translucent, smooth, rough, pale-green. The 

 plant is 2-3 ft. high, flowering between August 

 and October, and is a herbaceous perennial. 



Marsh Hair Grass (Deschampsia setacea, Hack. 

 D. uliginosa, Weihe = D. discolor, R. & S.). 

 The habitat of this grass is margins of peaty pools. 

 The stem is erect and slender. The leaves are 

 thread-like, folded. The sheaths are smooth. The 

 ligule is linear to lance-shaped. The panicle is 

 spreading, drooping at the extremity. The awn 

 is bent, twisted below, proceeds from the base of 

 the palea, and is longer than the latter. The 

 flower-stalk of the second floret is equal to half its 

 length. The plant is 1-2 ft. high, flowering in 

 July and August, and is a herbaceous perennial.
