Perennial. Kootstock extensively creeping, not ctespitose, with 
long subterranean leafless stolons terminating in leafy barren stems. 
Stems erect, very stout, rigid. Leaves very stiff, broadly linear, 
|)arallel-sided, abruptly-acuminated and hooded and mucronate at the 
apex, with numerous broad elevated ribs; sheaths compressed, anci- 
jntate ; ligule short, truncate, with an elongate central point. Panicle 
erect, pyramidal, equal, rather lax, very compound. Panicle-branches 
commouly 5 at the lower nodes of the rachis, somewliat unequal, all of 
them bearing numerous si)ikelets, diverging during and after flower- 
ing. Spikelets shortly stalked, ^hort, oblong-elliptical and compressed 
before fiowering, afterwards oblong-ovoid and greatly compresscid, 4- 
to 9-flowered, olive. Glumes sliglitly unequal, the upper one the 
larger, but considerably shorter than the lowest floret. Lower pale 
subobtuse, scarcely ^cariou.s ar tiie apt^x, with 7 prominent ribs. 
By the edges of ditches and slow river.s and ponds; rather common 
and generally distributed in England. Kare in Scotland, though ex- 
tending north to Haddingtonshire, Kincardine, Clackmaiman, and Loch 
of Lindores, Fife. In Aberdeenshire it is merely naturalised, according 
to Dr. Dickie's Botanist's Guide. It is also reported from Forfar and 
Moray; but th<^>e counties are so nmcli to the north of its ascertained 
limits that some proof uia}' be re(piired that it has not been planted. A 
single r<.>ot from Surrey, planted ;^ years ago in the bed of an old pond 
in Balmuto <iar(h'n, through wldch runs a small stream, has now 
extended until the plant occupies an area of about 30 s({uare yards; 
so that it is f.'vident if the })lant is once introduced it will soon have 
the appearance of boing a native. Very local in Irehind, an<l occurring 
England, Scotland, Iivlund. IVn-nnial. Lar^- Summer, Autumn.
