TRIANDRIA. MONOGYNIA. Carex. 



green, slender, shorter than the straw, upwards rough at the 



edge and on the keel. Male spikes single, strap-shaped, termi- 

 nating. Female spikes 3, at the base of the male, near together, 

 oblong, acute, more globular when ripe ; the 2 lower ones with 

 a short, sitting, green floral-leaf; the upper one floral-leaf mem- 

 branaceous, egg-shaped, keeled, ending in a slender green point. 

 Scales as long as the ripe capsules. Caps, turning black, roundish, 

 somewhat cottony, ending in a short, bluntish, undivided point. 

 Summits 3. The globular form of the female spikes happens 

 from the terminal florets being usually male, and deciduous ; as 

 these wither away, the spikes assume their round form, other- 

 wise they are in general oblong. The capsules are somewhat 

 cottony, as in C. proecox, but the strap-shaped male spike, the 

 sitting female spikes, and the reclining straw, mark its distinc- 

 tion in all stages of its growth. Goodenough.

Root thick, creeping. Straw 4 or % inches high, curved, 3- 

 cornered, angles very rough, rigid. Leaves dark, and rather 

 glaucous green, rigid, curved, shorter than the straw, towards 

 the end rough on the edge and the keel. M. spike single, 

 (rarely 2) terminating, oblong, pointed, £ inch long. Scales 

 black, egg-shaped, very blunt. Fern, spikes 3, near the male, 

 the lower farther off, oblong, pointed, sitting, (the lower often 

 on a fruit-stalk) | inch long, florets closely compacted, but the 

 lower ones more distant, 1 or 2 at the top, chiefly on the upper 

 spikes, male. Scales black, very blunt, but half the length of 

 the ripe capsule. FL La/] I to each spike, broad at the base. 

 Caps, egg-shaped, blunt, entire at the end, smooth, flatted on one 

 side ; sometimes longer, taper pointed, and crooked. Summits 2, 

 thick, white, hairy. This plant differs from the C montana ot 

 Huds. by having no sheath, 2 summits, and smooth capsules : it 

 differs also from the saxatilis of Linnaeus, by being thicker and a 

 much smaller plant; and from both by the great rigidity of its 

 leaves and its crooked straw. By its rigid and spreading leaves 

 ir may be known from the C. caespitosa, whose leaves are upright 

 ^nd soft, as well as from the stricta which is altogether upright. 

 Goodenough. L. Tr. ii. p. lf)3.
