In ditches, pools, and clay-piis. 



Annual. July, August. 



Differs from the last chiefly in its prickly stein, and more numerous 

 bracteas, which form whorls round the branches. It is often, in 

 like manner, incrusted. /3, in Bobart's herbarium at Oxford, 

 bears prickles under the upper flowering-branches only, but has 

 no other distinctive mark ; nor is it C. tomentosa of Linnaeus. 



3. C.fleccilis, Smooth Chara. 



Smooth, transparent, without prickles. Whorled branches 

 cylindrical, blunt, with a minute point, no internal parti- 

 tions ; some cloven. Bracteas none.
