CVI. CYPEEACEjE. 
[ Car ex. 
erect, 1 rarely 2 barren, fertile 3 — 4, lower one shortly stalked, 
sheaths none, lower bractea subfoliaceous with small round dark 
auricles, glumes elliptical or oblong obtuse, fruit plano-convex 
elliptical or obtuse with filiform nerves which disappear up- 
wards and an obsolete or evident entire beak. C. csespitosa

Marshes and wet pastures, frequent. If.. 5, 6. — A foot or more 
high, slightly creeping. Stem weak, acutely triangular, laxly ccespitose. 
Leaves slender, their sheaths not filamentose. Fruit flat at the back, 
3 — 5-nerved ; convex in front; 7 — 9-nerved. Achtnes broadly oval, 
compressed, with a short slender beak. We adopt the name given 
to this extremely common, but confused species, by Fries, being cer- 
tainly older than that of Gay. 
[29. C. Gibsoni Bab. ( Gibson's C .) ; “spikelets erect, 1 
barren, fertile 2 — 4 narrowed downwards slightly stalked, 
bracteas foliaceous with short auricles, fruit lanceolate acute 
with many nerves not reaching the summit and a short entire 
beak, achene broadly obovate very blunt with a short thick 
beak, stem acutely 3-angular or triquetrous rough towards the 
top.” Bab. in Ann. Nat. Hist. xi. t. 5. C. casspitosa (3. chloro- 
carpus Gibs. C. vulgaris (3. McLaren. 
Hebden Bridge, Yorkshire ; now lost by drainage. 2/.. 6 — Creep- 
ing. Stems 6 — 8 inches high. Leaves flat ; sheaths not filamentose. 
Glumes a third shorter than the fruit, which is gradually narrowed 
from below the middle to the top and nearly twice as long as the 
achene. The perigynium having lengthened out much beyond the 
achene, shows that this is in an abnormal condition, and probably of 
some other species ; Dr. Boott suspects it to be C. acuta, whilst 
Mr. Bahington thinks it more allied to C. vulgaris. We are not 
acquainted with it.] 
30. C. aquatilis Wahl. ? ( straight-leaved Water C .) ; spike- 
lets erect, 1 or more barren, fertile 3 — 4 nearly sessile cylindri- 
cal elongated attenuate below often acuminate with barren 
flowers at the extremity, sheaths none, bracteas long foliaceous, 
fruit broadly obovate without nerves broader than the glume 
with a very short entire beak, stem smooth obtusely triangular, 
leaves long straight narrow-linear. E ■ B. S. t. 2758. 
On table-land in boggy situations in the mountains of Clova ; and 
in the valley by the bridge at Clova. If.. 7, 8. — Stem 1 — 2 ft. high. 
Achene obovate, blunt with a short beak. Dr. Boott doubts if this 
be really the C. aquatilis of Wahlenberg, since that author describes 
his plant as having glumes much narrower than the fruit, which is 
spikelets ^ — 2 inches long (comprehending our sp. 28, 30. 31, and 33) ; 2. C. acuta, 
glumes mostly narrow and pointed, fertile spikelets 3 inches or more long (our 
sp. 32 and 29 ?) : and if they diffir by no more important characters than these they 
ought to be conjoined.
