CVI. CYPERACEJE, 
513 
bracteasform ; fertile spihelels more or less remote, the two upper 
subapproximate, the lowest sometimes 3 inches from the middle one. 
Beak about one third the length of the fruit. Achene triangular, 
ovate-rhomboidal, pointed at both ends, very minutely and closely 
dotted. Differs from C. distans in its smaller size, its light green, 
more approximate spikes, its more erect stem, and in its fruit. 
40. C. binervis Sm. ( green-ribbed C .) ; barren spikelet 
solitary with obtuse scales, fertile 3 — 5 the upper ones some- 
times subapproximate, the lower remote erect cylindrical often 
elongate bearing barren flowers in their upper half and some 
of them occasionally compound at the base, the lower stalks 
longer than the sheathing bracteas, glumes mucronate, fruit 
ovate triquetrous with a smooth rather broad bifid beak and 
two principal green submarginal nerves on the outer surface. 
Boott. — E. B. t. 1235. 
Dry heaths and moors, frequent. If.. 6. — Generally taller, and 
in every part more rigid, than the last. Glumes and especially the 
fruit, more highly coloured, the latter more acutely triquetrous with 
two nerves near the margin on the back, which are always green, 
though the rest of the fruit be more or less brown. Achene obovate, 
tapering at the base. 
41. C. Icevigdta Sm. (smooth-stalked beaked C.) ; fertile spike- 
lets remote erector drooping cylindrical stalked, stalks longer 
than the elongated sheaths, bracteas foliaceous, all the glumes 
acuminate or mucronate, fruit ovate triangular striate with 
a rather long acuminate beak deeply bifid at the point. E. B. 
t. 1387. 
Marshes and boggy thickets, in several places both of England and 
Scotland. Anglesea. Near Belfast. 2f. 6. — Stem 2 — 3 ft. high. 
Leaves broad, but rather short. There is rarely more than one barren 
spike, which is always triquetrous, with obtuse or sometimes acute 
glumes. Achene obovate, tapering at the base. Often in the young 
state confounded with C. sylvatica, and then most easily distinguished 
by its more compact spikelets and darker glumes ; it flowers too a 
month later. 
42. C. depauperdta Gooden, (starved Wood C .) ; barren 
spikelets solitary, fertile ones erect remote with very few 
(3 — 4) flowers, the stalks much longer than the sheaths, 
bracteas foliaceous, fruit large many-nerved nearly globose 
inflated terminating in a long bifid beak with rough edges 
longer than the (pale) ovate pointed glume. E. B. t. 1098. 
Dry woods, rare. Godaiming, Surrey ; Charlton Wood, Kent. 
Near Forfar: G. Don. 2f . 5,6. — Stem 1 — 1 j ft. high. Fertile 
spikelets very distant ; their few flowers, and large inflated beaked 
fruit, decidedly marking the species. Achene broadly obovate, with 
three blunt angles. Mr. Don cultivated it in his garden, which 
appears to have been the only locality for it “ near Forfar.”
