CVI. CYPERACEyE. 
[ Car ex. 
******* spikelets ( simple ) alternate, barren at their extremity. 
Rhizome creeping. 
22. C. arendria L. (Sea C.) ; lower spikelets fertile, upper 
ones barren, intermediate ones barren at the end, all crowded 
into an oblong interrupted spike, fruit ovate with a membra- 
nous margin nerved shorter than the acuminate glume, bracteas 
membranous lower ones somewhat leafy, stem triangular, leaves 
plane. E. B. t. 928. 
Sandy sea-shore, frequent, where it is of great service in binding 
the soil. If. . 6. — Rhizomes excessively long and creeping. Stems 
rough, 8 inches to a foot high. Fruit with a green membranous 
wing. 
23. C. intermedia Gooden. ( soft broivn C .): lower and 
upper spikelets fertile, the intermediate ones barren, all crowded 
into an oblong interrupted spike, fruit ovato-lanceolate with 
an acute narrow margin serrate upwards nerved longer than 
the glume whose midrib disappears below the summit, bracteas 
membranous the lower ones somewhat leafy, stem triangular 
with scabrous angles, leaves plane. E. B. t. 2042. C. disticha 
Huds. 
Marshy ground and wet meadows. If.. 6 Stems 1 — li foot 
high. Spikes, or heads of spikelets, similar in general appearance to 
the last. Fruit large, not so distinctly winged but gradually flattened 
towards the margin, more striate on its flat or inner side, the beak 
broader at its summit. Stem much taller, and the leaves less confined 
to the lower part of it. The name disticha is certainly the oldest, 
but is usually relinquished in favour of the more expressive one given 
by Goodenough. 
24. C. divisa Huds. ( bracteate Marsh C.) ; spikelets crowded 
into a somewhat ovate head, the lower ones simple or compound 
with a leafy erect bractea at their base, glumes with an excur- 
rent midrib, fruit roundish ovate convex on one side slightly 
concave on the other, beak acutely bifid with finely serrate 
edges, stem roughish at the summit. E. B. t. 1096. 
Marshy places, especially near the sea, principally in the east of 
England, and in Angus-shire. If. . 5, 6. — Stems about 1 foot high; 
lower bracteas mostly with a long leafy point. 
iv. Terminal spikelct androgynous, the rest fertile. Stigmas 3. 
25. C. Vdhlii Sehk. (close-headed Alpine C.) ; spikelets 1 — 4 
oval or oblong obtuse aggregate the terminal one with barren 
flowers at its base, stigmas 3, fruit obovate triquetrous with a 
short notched beak scabrous above with crystalline points longer 
than the ovate somewhat obtuse glutne, stem triangular rough 
at the edges towards the summit. E. B. S. t. 2666. C. alpina
