SEDGE TRIBE 41 
leaves 2 or 3, channelled and keeled. Found only on the banks of St. Ouen’s 
Pond, Jersey ; flowering in June and July. 
5. Blunt-edged Club-rush (8. carindtus).—Stem round below, obtusely 
triangular above; spikelets in a compound terminal panicle. Growing in 
muddy tidal waters in Middlesex, Kent, and Cornwall, where it attains a 
height of 2—4 feet; very rare, flowering in July and August. Like 
S. tabernemontani, this is by some regarded as a sub-species of S. lacustris. 
* * * Snikelets numerous ; stem triangular, leafy ; stigmas 3. 
6. Salt-marsh Club-rush (8. maritimus).— Spikelets arranged in 
several stalked and sessile clusters; bracts several, long and _ leafy. 
Common in salt marshes on most parts of the coast, where it flowers in 
July and August, forming large grassy tufts of long keeled and channelled 
leaves, which frequently overtop the clusters of brown spikelets. Both 
leaves and stems are very harsh to the touch. 
7. Wood Club-rush (S. sylvdticus).—Spikelets forming a many-times- 
compounded terminal panicle; bracts several, very long, leaf-like. Moist 
woods, most frequent in the south of Scotland, but abundant also in South 
Kent, and occasionally met with on the banks of the Tamar, Devonshire. 
A robust and handsome species, 3—4 feet high, with broad and flat leaves, 
and a very large number of small green spikelets, clustered together in 
groups of three or four. It flowers in July. 
** * * Snikelets solitary, te-manal ; stigmas 3. 
8. Chocolate-headed Club-rush (8S. pawiflérus).—Stem round; sheaths 
leafless ; two outer glumes obtuse, shorter than the spike, usually awned. 
Boggy moors and commons in Scotland, and several parts of England. The 
stems are 4—10 inches high, resembling in habit those of Hledcharis palustris, 
but well distinguished by the above characters, as well as by the differently 
formed fruit. It flowers in July and August. 
9. Scaly-stalked Club-rush (S. cespitésus)—Stem nearly round ; 
sheaths with narrow awl-shaped leaves; two outer glumes acute, longer 
than the shining brown spikelet. Moist heaths, common. A small plant, 
2—4 inches high, with numerous erect stems, many of which bear no 
spikelets. ‘This plant is called Deer’s Hair in the Highlands, and yields an 
abundant food to sheep on the mountains in spring.”—Sir WV. J. Hooker. 
It flowers in June and July. 
10. Least Club-rush (S. parvulus).—Stems grooved; sheaths thin, 
glassy and inconspicuous; leaves bristle-like, channelled, dilated at base. 
Spikelets pale and minute. This plant, which grows on sandy seashores in 
Hampshire, Dorset, Devon, and Wicklow, is a very small one, its full height 
not exceeding a couple of inches. Its rootstock is hair-like, and creeps along 
in the sand, throwing up distant tufts of a few stems and leaves. It flowers 
in July. 
9. CoTrron-GRASs (Hridphorum). 
* Swikelet solitary. 
1. Alpine Cotton-grass (£. alpinum).—Stem triangular, rough ; leaves 
bristJe-like, much shorter than their sheaths; spikelet oblong, few flowered ;
