 barren. There is a short rootstock. The scales 

 are overlapping, numerous, leafless, acute. The 

 sheaths are short, awl-like below, the lower split, 

 large, stout, rigid, the upper slender. The leaves 

 are short. The spike is solitary, terminal, ovate, 

 with few flowers. The spikelets are erect, chest- 

 nut - brown, shining. The lower 2 glumes are 

 awned, and longer than the spikelet. There are 

 4-6 bristles. There are 3 long stigmas. The fruit 

 is an oblong to inversely ovate brown nut, with a 

 long narrow point, and a few erect teeth. The plant 

 is 6-1 J in. in height, and flowers from June to 

 .August. The plant is a herbaceous perennial.

 gravelly places. The stem is tufted, round, leafy, 

 slender, rigid, round in section. The leaves are 

 1-2, narrow, channelled, short, bristle-like (hence 

 selaceus). The spikelets are 1-3, terminal, small, 

 stalkless, shorter than the lower bract, which 

 appc.irs as a continuation of the stem. The 

 glumes are blunt, with a short point, brown, with 

 white margins and a green keel, ovate. There 

 are 2-3 stamens and 3 stigmas. The nuts are 

 brown, broad, 3-angled, inversely ovate, longi- 

 tudinally ribbed, and transversely striate. The 

 plant is 3-6 in. in height, flowering in July and 

 August, and is a herbaceous perennial. 



Kobrtsia caricina, W'illd. ( = A", biparlita, Dal. 

 Tor.). — The habitat of this plant is alpine marshes, 

 upland moors. The plant has the sedge habit. 

 The stems are erect, densely tufted, rigid, round 

 in section, le.ily below. The rootstock is short. 

 The leaves are wiry, bent-back, slender, not so 

 long as the stem, grooved, the margins twisted. 

 The spikes (4-5) are n.'irrow, close, at the top of the 

 stem, with 6-8 flowers. The spikelets are nearly 

 in 2 rows, stalkless, cylindrical. The bracts are 

 small. The glumes are rigid, ovate to oblong, 

 blunt, p.ile-brown, the second of the lowest fertile, 

 the lowest barren, the third male. Both flowers 

 are male in the upper spikelets. The nut is pale, 

 linear, with a beak. The plant is 4-8 in. high, 

 flowering in .August and September, and is a 

 herbaceous perennial. 



Few-flowered %e^%f:{Carex pauciflora, Lightf.).

 bogs. The plant has the sedge habit. The root- 

 stock is slender, creeping, with stolons. The 

 stems are 3-angled, smooth, slender. There are 

 2 to 3 bristle-like leaves, not so long as the stem, 

 which are rolled inwards. The plant is monoecious.

 plant is moist shady places, dry hedgebanks. It 

 has been regarded as a sub-species of C. miiricata. 

 The stems are 3-sided, loose, curved, slender, 

 limp, with rough angles above. The spikelets 

 are distant, loose, drooping, the upper close, 

 greyish, 1 or 2 of the lowest lengthened into a 

 long branch. The bracts are bristle-like. The 

 glumes are blunt, shorter than the fruit. The 

 fruit is ovoid, acute, plano-convex, with a thick 

 green margin, with obscure veins, divided into 

 2 nearly to the base, smooth, ascending. The 

 beak is rough-edged. The nut is ovoid to oblong, 

 flattened, the beak short. The plant is 1-2 ft. 

 high. It flowers from May to July, and is a herb- 

 aceous perennial. 



Prickly Sedge (Carex echinala, Murr. = C. slel- 

 liilata. Good). — The habitat of this sedge is moors, 

 bogs, and marshes. The habit is that of a sedge. 

 The stem is 3-angled, more or less smooth or 

 rough above, without stolons. The rootstock is 

 densely tufted. The leaves are narrow, channelled, 

 not so long as the stem. The 3-4 spikes are pale- 

 green, round, distant, spreading. The bracts are 

 small, usually at the bottom of the spikes. The 

 glumes are green, with pale-brown sides, ovate, 

 .'icute. The fruit is olive-green, stalkless, with a

 ovoid, narrow below, the glume not so long as 

 the fruit. The plant is 4-12 in. in height, flowering
