In ditches, pools, and clay-pits. 



Annual. July, August. 



Differs from the last chiefly in its prickly stem, 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. Q.flexilis. Smooth Chara. 



Smooth, transparent, without prickles. Whorled branches 

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

 tions ; some cloven. Bracteas none.

In ditches, ponds, and rivers. 



First observed by Buddie, in ponds at Henley, 4 miles north of

 Rev, E. Williams, in Berrington pool, Shropshire ; and the Rev. 

 Dr. Abbot, in the river at Bedford. 



Annual. April — August. 



Slender, quite smooth, naked, green and pellucid. Whorled 

 branches either undivided, forked, or three-cleft. Anth. at the 

 forks of these branches, chiefly the upper ones, naked, solitary, 

 dull red, with numerous minute cracks. Germ, either adjoining 

 to the anther, sometimes in pairs ; or in similar situations on a 

 separate plant.
