Carex buxbaumii, Wahl. {= C. fasca, All. = C. 

 polygama, Schkuhr). — The habitat of this plant is 

 stony banks, spongy bogs, and wet places. The

 rigid sheaths, the edges net-like, filamentous. The 

 lower bracts are leafy. The spikelets are ^-^, 

 oblong, blunt, close, the lower distant, shortly- 

 stalked. The glumes are rounded, blunt-pointed, 

 the lower longer than the fruit, nearly black, or 

 dark-red-brown, with a green keel which is blunt- 

 pointed. The fruit is bluish-green, oval, ellipsoid, 

 blunt, flattened, 3-.angled at length, divided into 2 

 nearly to the base, shorter than the glumes, with 

 slender ribs. The nut is 3-sided, inversely ovoid, 

 brown, with white dots. There is no beak. The 

 plant is 1-2 ft. in height, flow'ering in July, and is

Tufted Water Sedge (Carex siricta. Good. = 

 C. el :ta, A11. = C. HudsoTiii, A. Benn.).— The habi- 

 tat of this plant is marshy and peaty places. The 

 plant has the sedge habit, and is slender. It is 

 densely tufted. The stems are rigid, 3-sided, 

 slightly rough above. The leaves are long, limp, 



erect, flat, narrow, the margin rolled back when 

 dry, with long, reddish-brown, shining, filament- 

 ous leaf-sheaths, the lower leafless. The fertile 

 spikelets are stalklcss, erect or drooping, long, 

 cylindrical, 1-3, sometimes male above, stout, 

 the male spikelets slender, 1-2. The bracts 

 are variable, auricled, the lower leaflike, short. 

 The fruit is rounded to egg-shaped, oblong to 

 elliptic, acute, flattened, veined, closely overlap- 

 ping, with green nerves, dark-purple, and with a 

 green keel, in 6-g regular rows, larger than the 

 glumes, and a sheathing beak. The beak is short, 

 notched. The glumes are pitchy, dark-brown, in 

 8 rows, egg-shaped, blunt, short-pointed, the 

 lower with an excurrent rough midrib. The 

 glumes of the male spikelets are narrow, acute. 

 The nut is inversely egg-shaped, round, short- 

 beaked. The plant is 1-3 ft. high, flowering be- 

 tween May and July, and is a herbaceous per- 

 ennial. 



Carex caspilosa, L. — This species has been re- 

 ported from Yorkshire, but needs confirmation,

Common Sedge (Carex Goodenovii, Gay = C. 

 vulgaris, Fr. = C. ccespitosa, Sm. non L.). — The

 base sometimes. The beak is stout, round, entire, 

 smooth. The bracts are leaflike and have no

 broader than long, lenticular, rarely 3-sided. The

 .August, and is a herbaceous perennial. 



Water Sedge (Carex aqualilis, Wahl.). — The 

 habitat of this plant is bogs and marshes, alpine 

 bogs, riversides, watery places. The plant has 

 the sedge habit. The rootstock is tufted, creep- 

 ing, and stoloniferous. The stems are stiff, 3- 

 angled with convex faces, stout, polished, leafy 

 below. The leaves are long, erect, the margin 

 rolled inwards when dry, the sheaths leafy, not 

 webbed. The 3-6 spikelets are erect, cylindric, 

 slender, stalked below, the males {1-3) are slender, 

 the fertile spikelets long, narrow below, the lower 

 stalked. The glumes are oblong or egg-shaped, 

 short, blunt, dark, narrower than the fruit, purple, 

 with a pale midrib. The fruit is yellowish-green, 

 somewhat rounded, egg-shaped or inversely so, 

 flattened, pale, smooth, nerveless, larger than the 

 glumes, lenticular or 3-sided. The nut is oblong,
