then gives the beak a triangular form ; but tbe beak is often as 
compressed as in C. paradoxa. A form of this species, with the 
habit of C. paradoxa, occurs near Manchester, and at Malbarn Tarn 
in Yorkshire. 
19. C. vulpina { great C.) ; spikelets compound collected 
into a cylindrical crowded spike, fruit ovate-acuminate plano- 
convex nerved longer than the glume divergent, beak finely 
serrate bifid, stem very acutely triangular the angles scabrous, 
leaves broad. E. B. t. 307. C. neinorosa Willd. 
Wet shady places, especially near water. %. 6. — Two feet or 
more high ; stem stout, rough, as are the margins of the broad leaves. 
Bracteas setaceous. Spike large, greenish. Fruit pale, not gibbous 
as in the three preceding species, rough at the margin of the 
lengthened beak, and bifid at the point. Achene oval, compressed, 
with a very short beak ; the beak is slightly thickened at the insertion 
of the greenish base of the style in this and several of the allied 
species, and also in the two next; in C. vulpina it is usually 10 or 12 
times shorter than the achene, and about twice as long as in C. 
divulsa, while in C. muricata it is intermediate. 
****** Spikelets simple, alternate, barren at their extremity. Root 
tufted. 
20. C. divulsa Gooden, {gray C .) ; spike elongated lax con- 
sisting of 5 — 6 simple spikelets which are subremote below 
with pale membranous acute scales; fruit ovate acute sube- 
rect obscurely nerved rough at the point with blunt margins 
longer than the mucronate pale membranous glume, stem with 
rough angles. E. B. t. 629 {young). C. muricata (3. Wahl. : 
MEaren. 
Moist shady pastures, not rare. 2/.. 5, 6. — This species resembles 
the next : the fruit is scarcely so acuminate, and somewhat erect 
instead of diverging, and the achene is rather narrower ; the colour of 
| the whole plant is paler, the spikes more elongated and slender, and the 
spikelets more distant. “ The slight difference in the distance of the 
spikelets is not a specific character, and I doubt whether the differ- 
ence in the glumes is sufficient to constitute C. divulsa a distinct 
species, especially when we find such a suspicious intermediate form 
as the C. muricata virens of Andersson.” ■ — M'Laren. 
21. C. muricata L. {greater prickly C .) ; spike oblong of 
4 — 6 compact or approximate simple spikelets with brownish 
ovate pointed scales, fruit ovate-acuminate spreading obscurely 
nerved with acute rough margins longer than the mucronate 
brown glume, stem with rough angles. E. B. t. 1097. C. 
spicata Iiuds. 
Marshy and especially gravelly pastures. 2/. . 5, 6. — Stem 1 — 2 ft. 
high, slender. Bracteas small, lanceolate, subsetaceous. Fruit yel- 
lowish-brown, broad, rather large.
