49. C. ustulata Wahl. ( scorched Alpine C.) ; fertile spikelets 
about 3 oval densely flowered drooping, the stalks about twice 
the length of the loose sheaths, bracteas setaceous, fruit ellip-

Tufted, and scarcely creeping. Stem, in the only Scotch specimens 
we have seen, from 3 to 8 inches, in Lapland ones about a foot high. 
Leaves short, broad, principally from near the root. Fertile spikelets 2, 
usually 3, on slender drooping stalks, and of a deep purple-black 
colour ; barren one rather smaller, and of a dark rusty-brown. Fruit 
very obscurely nerved, perhaps nerveless.

elongated sheaths, bracteas foliaceous, glumes ovate acute 
diaphanous with a green keel, fruit broadly ovate acuminate,

Moist woods, frequent. If., 5,6. — Similar to C. strigosa ; but the 
spikelets are shorter, broader, and on longer stalks ; fruit very different, 
glabrous, and so acuminate as to terminate in a long&eai; glumes 
longer in proportion. Spikelets sometimes compound. 
51. C. Pseudo -ajperus L. (Cyperus-like C.) ; barren spikelet

stalks drooping, bracteas very leafy, lowermost sometimes 
sheathing the others without sheaths, glumes setaceous sca-

deeply cloven. E. B. t. 242. 
Moist places, by the sides of lakes and ponds ; not very general.
