This plant, which was inserted in the Encyclopedia Methodique by La 

 Marck? has not recently been seen in this country. I have inserted it, as it is 

 said to belong to Carolina, and at the same time to note that the expanding 

 involucrum and large ray by no means apply to the Verbesma femuata. 

 Whether really a native of the United States remains perhaps yet to De 



ascertained.
