riety of C. anceps, and the reference of this figure should uu- 
questionably be to this species. Schkuhr was probably led 
to consider this variety of C anceps as belonging to C. plan- 
taginea. from the striking resemblance of the leaves of the 
two plants, while in every other res;ect they are different. 
This difference is sufficiently obvious to those who are fa- 
miliar with both. Mr. Elliott observes that this species has 
been to him “ obscure ;” a fact which others have found too 
true. It is hoped that this attempt to remove the principal 
causes of obscurity in ascertaining this plant, will be an ade- 
quate reason for the length of these remarks.

Flowers in May—grows in wet situations. Abundant in 
all its varieties at Niagara Falls near Tuble Rock, with C. 
pyriformis, C. scirpoides, C. stipata, &e Though I found 
C. pyriformis, with C. alba upon Goat Island, I did not see 
C. Oederi on the Americanside. Penn. Schw.
