1 Determined by Prof. A. Braun of Berlin. The CharacecB are little understood by botanists generall7 
and it is not thought advisable to endeavor to give either generic or specific characters in this place' 
Nitella, 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 mteUa the nutlets have a very faint coronula or none, and are fe'w-striate 
while in Chara the coronula is distinct and persistent, and the nutlets are many-striate.— D. C, E. '
