CYPERACE^E. 
*** Bristles 0. — f Spikes solitary. 
11. S.fuitans (L.) ; st. floating branched leafy, 1. fasciculate, 
fl. -stalks alternate with a sheathing 1. at the base, spikes terminal 
solitary ovate few-flowered, glumes obtuse keeled membranous 
at their edges, 2 outer ones larger shorter than the spike and in- 
closing it, nut obovate, bristles 0, stitjmas 2. — E. B. 216. St. 85. 2. 
— St. rooting from the lower joints and spreading to a great ex- 
tent in a zigzag manner. The fascicles of 1. and stalks springing 
from the joints of the stem exactly resemble the separate csespi- 
tose plants of the preceding species, and I do not consider the 
absence of the bristles and one of the stigmas as a sufficient rea- 
son for removing it from the genus. — Ditches and ponds. P. 
VI. VII. 
ft Spikes 1—3. 
12. S. setaceus (L.) ; st. terete leafy at the base, spikes ter- 
minal, lower bract elongated so as to resemble a short continua- 
tion of the st., glumes obtuse mucronate, nut trigonous obovate 
longitudinally ribbed and transversely striated, bristles 0, stigmas 
3.—E. B. 1693. St. 10.— St. tufted, slender, 3—6 in. high. 
Spikes small, sessile, considerably shorter than the lower bract. 
Glumes brown with whitish margins and a green keel. — Wet 
sandy and gravelly places. P.? VII. 
13. S. Savii (S. and M.) ; st. terete leafy at the base, lower 
bract shorter or slightly longer than the terminal spikes, glumes 
obtuse submucronate, nut subglobose rouyh with slightly elevated 
points, bristles 0, stigmas 3. — E.B. S. 2782. — Closely resembling 
S. setaceus. Spikes varying considerably in length, sometimes 
i in. dong. Glumes scarcely mucronate, greenish, usually with 
a brown spot on the upper part of each side. — 12. monostachys 
(Hook.); spike small solitary, bract very short. Isolepis pygmtea 
Kunth. — S. supinus (L.) is closely allied to this but has trans- 
versely rugose nuts. — In many places near the coast. P. VII. 
fff Spikes numerous, in heads. 
14. S. Holoscheenus (L.) ; st. round, spikes in dense globular 
sessile or stalked heads, lower involucral bract erect long, glumes 
obovate emarginate mucronate : lobes rounded as long as the 
mucro. — E. B. 1612. — St. 3 — 4 feet high, round quite up to the 
cluster. Upper bract patent or ascending. Glumes variegated 
with fuscous and white, pilose. Anth. with an elongated entire 
point. — My friend Mr. R. M. Lingwood gathered at Watchet, 
Somerset, a plant which may probably prove to be a new species ; 
it differs from this plant in the following points — (2. elegans ; st. 
compressed just below the cluster, glumes obovate rounded with 
a projecting mucro, anth. with an elongated point terminating 
in 3 teeth. — Sandy coast of Somerset and Devon, rare. P. IX. — E.
