Oenothera triloba Nutt. 
Jefferson County, May 1, 1918. No. 24,580. Common on a 
washed, sterile, sparsely wooded slope of the bluff of the Ohio River 
just east of Madison. Associated with Opuntia Rafinesque, Plantago 
virginica, ete. A specimen of this species was sent me from Wash- 
ington County in June, 1917, from near Salem, by W. H. Rudder. 
Oenothera triloba parviflora Wats. was reported in Coulter’s Cata- 
logue for Blatchley from Monroe County, but Blatchley’s original 
manuscript of the flora of Monroe County does not give this species, 
but does give Oenothera biennis parviflora. In Coulter’s Catalogue 
the species was reported under a revised nomenclature, and it is 
believed an error was made in transferring it. Therefore it is here 
proposed to drop from our flora Oenothera triloba var. parviflora, 
which is as yet known only from the area west of the Mississippi.
