lens; it appears circum- 



scribed in its habitat, as I have heard of it in no other part of the coun- 

 try, and it was unknown to Dr. Muhlenberg except by Walter's de- 

 scription when 1 sent him specimens. As the F. tripetala of Thua- 

 berg has been rctuoved to the genus Mor«ea, I have retained Walter's 



na'ue.
