bifid at the point, lower bracteas very long and narrow leafy 
reaching beyond the spike. E. B. t. 832. C. tenella Schk. 
Woods and moist shady places, y.. 6 Slender, pale green, 
14 — 1 foot high. Resembling the following, but “the stem has 
blunter angles ; the lowest bractea is much longer than in that 
species; the leaves are compresso-canaliculate (with incurved sides) 
and much narrower ; the glumes, too, are narrower, their nerve quite 
smooth, discontinued below the membranous summit:” Wilson. Fruit 
serrate above the middle. Achene ovate, pointed. 
14. C. axillaris Gooden, (axillary -clustered C.) ; spikelets se- 
veral very distant and compound below crowded and simple 
above, fruit longer than the glume oblong-ovate shortly acumi- 
nate plano-convex acutely angled, the beak deeply bifid, lowest 
bractea foliaceous as long as or longer than the spike, the middle 
ones setaceous shorter, upper ones with a point scarcely so long 
as the spikelet. E. B. t. 993. 
Marshes, rare. Middle and south of England; and as far north 
as Lancashire and Yorkshire. 2J-. 6.— Stem with 3 acute angles; 
spikelets with more numerous flowers than the last, lower one or two 
compound. Glumes with 2, close, green, generally rough nerves, 
reaching to the summit, hence more rigid. Fruit serrate above the 
middle. Achene obovate, pointed. 
15. C. Boenninghausiana Weihe (Boenninghausen's C.) ; spike- 
lets several distant and more or less compound below crowded 
and simple above, fruit as short as the glume ovate-acuminate 
plano-convex acutely angled, the beak deeply notched on one 
side, lower bractea foliaceous as long as the spike, middle ones 
shortly setaceous scarcely so long as the spikelets, upper ones 
pointless. Coleman in E. B.S. t. 2910. C. axillaris /3. Bromf. 
Marshes and by the sides of ponds, rare. Balls Wood, Hertford ; 
Esher, Surrey ; Pulborough and Hastings, Sussex. Killin, Perthshire; 
Culreach near Gordon Castle, Banffshire; Crichton Castle near 
Edinburgh. 7J.. 6. — Several (4 — 6) of the lower spikelets are com- 
pound and distant. Very closely allied to the last, and most pro- 
bably a mere variety of it ; the chief distinction lies in the more 
luxuriant inflorescence, which is sometimes a foot long. Stem with 
slightly convex sides and 3 rough angles. Glumes pale brown with a 
scarious margin smooth. Fruit with the edges blunt at the base, sharp 
and serrate from below the middle. Achene ovate-elliptical, pointed. 
***** Spikelets alternate, barren at the extremity, the lowest or most of 
them compound, all more or less approximate. Bracteas not 
foliaceous. Root tufted. 
16. C. paniculdta L. ( great panicled C.) ; spike panicled 
consisting of ovate spikelets arranged on the elongated diverging 
branches of a common axis, fruit ascending ovate plano-convex 
gibbous on the back ; faintly many-nerved margined above and
