1 Determined by Prof. A. Bkaun of Berlin. The Characece are little understood by botanists generally, 

 and it is not thought advisable to endeavor to give either generic or specific characters in this place. 

 NUella, however, has always a stem composed of a single tube, and the fruiting rays are branched or 

 forked, while Chara has usually a stem composed of several tubes covered with an epidermis, and the 

 fruiting rays are simple. In Nitella the nutlets have a very faint coronula or none, and are few-striate, 

 while in Chara the coronula is distinct and persistent, and the nutlets are many-strlate. — D. C. E.
