I give the habitat with some hesitation. But among my specimens I found 

 one put away for examination in the manner I have usually put specimens 

 received from some of my. domestic correspondents; in this instance, how- 

 ever, without a note or label. On examination it proved to be a male plant 

 of this species, justifying Mr. Brown^s observations on its dioecious character. 

 (Trans* Lin. Soc. vol. 12. p. 123.) The specimens in my herbarium from 

 the Northern States are female. 



Flowers August — September.
