confusion in this genus. The prairies of Ohio produce seve- 
ral species which are as yet unpublished. I have drawn some 
descriptions from living plants, which I shall be happy to com- 
municate, accompanied with specimens, to any botanist who 
will attempt a complete monograph. As it is inconsistent 
with the design of this Synopsis to insert long and minute de- 
scriptions, I prefer to omit all but suchas have heretofore been 
‘determined.
