green on the keel, a little longer than the fruit. Colour otf 
the plant bright green, of the spikes dark. 
Flowers in May and June—grows in marshes; common. _ 
This is a variable species, and was named C. mufabilis by 
Willd. in Prodr. Beil, In Schk. there are eight figures in 
its different states exhibiting two varieties. It is generally 
recognised without difficulty from its form and the roughness 
of its culm and leaves. It often grows in large, elevated, 
dense bogs.

Spica staminifera solitaria, seepe binis, erecta oblonga, in- 
itma sessile ; spicis fructiferis distigmaticis ternis oblongo- 
cylindraceis subdensifloris sessilibus, spe apice staminiferis ; 
fructibus ovalibus et obovatis utrinque convexis obtusis ore 
integro et protruso glabris, squama oblonga obtusa paulo lon- 
gioribus. 
_ Culm 12—20 inches high, triquetrous, slightly scabrous 
above, leafy ; leaves linear-lanceolate, shorter than the culm, 
abbreviated below, sheathing towards the base ; bracts leafy, 
linear-lanceolate, rather shorter than the culm and without 
sheaths; staminate spikes one or two, oblong, lowest sessile ; 
staminate scale oblong, obtuse, purplish brown on the mar- 
gin, whitish on the keel; stigmas two; pistillate spikes 
three, sometimes staminate at the apex, cylindric, rarely two 
inches long and often less than one, sessile, nearly erect, low- 
est slightly pedunculate, rather densely flowered ; fruit oval 
er obovate, obtuse, with an entire and protruded mouth, gla- 
brous ; pistillate scale oblong, obtuse, rarely lanceolate and 
obtuse, nearly black on the margin, green on the keel, and a 
little shorter than the mature fruit. The whole plant is of a 
light green colour or yellowish green, and is rather soft to the 
touch. 
Flowers in May—grows in dense patches along the banks 
of streams, and is often overflowed by the rise of waters ; 
common, but not abundant. 
Four varieties of this species are figured by Schk., but they 
are easily recognised. On our specimens the pistillate 
spikes are longer than those represented on the figures of 
Sehk., er on my specimens received from England, This
