Found by Mr. Borrer in Sussex. 



" Distinguished from C. Hedwigii principally by its more 

 flexible stems and more oblong nucules. When dry, it is 

 scarcely at all brittle, whereas C. Hedwigii is extremely so, 

 whence it is called C. fragilis by some authors." 



Perhaps merely a variety of C. HedwigiL 



4. CHARA ASPERA. 



Char. Stem very slender, scarcely brittle, obscurely striated 

 beset with scattered, spreading, or dejlexedbristles. Branches 

 of the whorls subulate ; the fertile ones with many whorls 

 of short ramuli or bractece, the two innermost longer than 

 the rest, bearing the globules or nucules which are 

 generally separate.

" Found in bog pits, and still waters in several places in 

 the north of England and Scotland. Stem one or two feet 

 long, densely crowded, every where beset with acute, slender, 

 straight, spreading or deflexed bristles ; and having at the base 

 of each whorl a row of appressed bristles, connected in pairs, 

 of which one points upwards and the other downwards. 



"Between the outer circle of tubes and central one, 

 in both the stems and branches, is found a green parenchyma, 

 arranged in lines alternating with the stride, and separated or 

 broken transversely at intervals, giving them a spotted ap- 

 pearance ; globules and nucules solitary, often on separate 

 plants. 



" I have had this species under cultivation in a glass jar for 

 several years, and although no nucules appeared at any time 

 upon it, young plants were copiously produced every spring."
