About the banks of the Thames, between London and Putney, in 

 several places. Mr. Newton. In Battersea fields, and near 

 Norwich. 



Annual. July, August. 



Root of several stout fibres. Stems one or more, from 6 inches to 

 2 feet high, simple, spreading, jointed, leafy, striated ; angular 

 and rough at the top. Leaves lanceolate, taper-pointed, harsh 

 on both sides, very rough at the edges ; their sheaths long and 

 smooth. Stipula of numerous short hairs, continued a little way 

 down the margins of the sheath. Panicle compound, 2 inches 

 long, erect, somewhat lobed ; the branches short, about 4 in a 

 whorl, each of several flowers, every pair of which is accompa- 

 nied by about 2 channelled, angular bristles, longer than the 

 whole branch, and rough with minute teeth directed downwards. 

 Fl. generally in pairs, oval, each inserted into a little terminal 

 disk, or cup, close to the bristles. Cal. pale with green ribs, 

 smooth and even. Cor. almost as large as the calyx j both valves 

 very minutely wrinkled, or dotted, at least in the perfect floret, 

 and constituting a rigid shining coat to the seed, inclosed in the 

 permanent, but loose and unaltered, larger valve of the calyx.

In Battersea fields. Curtis, Sowerby. On the west side of Norwich, 

 with the preceding.

Smaller than the foregoing, but often so like it, that few persons 

 can distinguish them. The spike however is neither lobed, nor 

 whorled. Bristles more numerous, though often, as Ray found 

 them, not so prominent. The most essential distinction, pointed 

 out by Mr. Curtis, consists in the minute teeth of these bristles
