14 CHARACEA AMERICANA. 
The third node is usually sterile, though occasionally we may find an _ intra- 
verticillate antheridium and rarely a nodal sporangium ; in the latter instance we have found 
two terminal leaflets, or one leaflet pee another node and one terminal leaflet. The 
figure in Kutzing’s Tab. Phyc. VII, 34, isunlike anything we have ever seen, viz., a simple 
fork with ¢wo terminal leaflets, or with one terminal and one forking leaflet, or with a ter- 
minal leaflet cons¢sting of three cells. 
Habitat. We have specimens gathered by Mr. Le Roy at Peekskill, N. Y., by Rev 
Mr. Wolle from northern N. Jersey (from these our figures were drawn, and we have 
gathered it in Long Island, and in pete R. I.; it is also reported from Rhode 
Island (Dr. Robbins) and from Michigan (Dr. Cooley). 
In N. Jersey it grows with Chara sejuncta and Chara Hydropitys. Doubtless it will 
be gathered in various parts of the country in quiet, shallow waters. It may be gathered 
in this latitude from July to September.

the first, sterile, node of the leaf ; ‘*3,” the second, fertile, odes occasionally sterile as at 
‘¢6* ; 4, the third node bearing three rays, or at ‘‘7” two rays and one terminal leaflet ;
