southeastern States. Ascyrum is essentially a southeastern 
genus, and this species, which is its northernmost representative,

areas. In Ohio it grows in dry upland woods and hillsides in 
the southeastern part. Specimens are in the State Herbarium 
from Hocking, Lawrence, Fairfield, Gallia, Scioto, Hamilton and
