200 ALIEN FLORA OF BRITAIN 



CHARACE^. 



Chara Braunii, Gmel. Widely distributed as a native 

 of Central and Southern Europe and Northern Africa, 

 reaching as far north as Belgium, Sweden, and Norway. 

 In England it has been found only in one place, viz., 

 by Mr. Charles Bailey (Journal of Botany, 1884, p. 4) in 

 warm water from cotton-mills near Reddish in South 

 Lancashire. The use of Egyptian cotton in the mill and 

 the presence of an undoubtedly Egyptian aquatic in 

 the same locality suggest introduction with the cotton. 



SALVINIACE^. 



Azolla caroliniana, WiUd. A native of the United 

 States, recently introduced into English gardens and 

 tending to spread into ponds and ditches.
