In waste, as well as cultivated, land, every where. 

 y. On the sea coast, not uncommon. 



Root long, creeping deeply and widely, so as to be very difficult 

 of extirpation;, jointed, clothed with membranous sheaths ; the 

 fibres downy. Stems slender, erect, 2 feet high, most leafy 

 below J round, striated, and smooth, at the top. Leaves of a 

 dull, somewhat glaucous, green, linear, fiat, spreading, gene- 

 rally all directed one way ; their margin and upper side rough. 

 Sheaths tight, ribbed, smooth, or a little hairy. Stipula short, 

 finely notched. Spike 2 or 3 inches long, erect, fiat, of nume- 

 rous, pretty close, elliptic-oblong spikelels; the main stalk some- 

 times hairy, especially at the edges. Florets from 4 to 8 or 9, 

 the colour of the foliage. Valves of the calyx lanceolate, ribbed, 

 pointed or awned. Outer valve of the corolla similar, but with 

 fewer ribs, and those chiefly towards the summit, which ends 

 cither in a short point, continued from the keel, or in a terminal 

 rough aiv7i, various in length, but seldom longer than the glume 

 itself 3 inner valve obtuse, or notched, awnless. The maritime 

 variety y is rather stouter and shorter in habit, all over more or 

 less glaucous, though variable in that respect, and certainly a 

 mere variety. The leaves are often involute. 



Schrader describes a more remarkable state of this grass, figured 

 in Leers 1. 1 2, /. 4, 1 , in which a great part of the spikelets in 

 the lower portion of the spike are double, or in pairs, contrary 

 to the generic character. But the creeping root distinguishes 

 this variety from the following species, with which it is con- 

 founded by Leers ; both being indeed considered by him as be- 

 longing to T. repens.
