The Flora of the Cayuga Lake Basin 369 



1. Verbascum (Tourn.) L. 



a. Plant densely tomentose; flowers nearly sessile, in a dense spike. 1. V. Thapsus 

 a. Plant not tomentose ; flowers slender-pedicelled, in an open raceme. 



2. V. Blaitaria 



1. V. Thapsus L. Common Mullein. 



Dry gravelly and sandy fields, mostly in the less strongly acid or the neutral soils ; 

 common. July-Sept. 



In the Cayuga Lake Basin, most abundant in the gravels at McLean, in the delta 

 gravels near Cayuga Lake, and on the stony lake and ravine slopes. 



N. S. to S. Dak. and Calif., southw. to Fla. and Kans. Naturalized from Eurasia. 



2. V. Blattaria L. Moth Mullein. 



Dry gravelly, more or less calcareous, fields and waste places, rarely in clay ; 

 frequent. June-Aug. 



Que. to Oreg. and Calif., southw. to Fla. Naturalized from Eurasia. 



Two color forms occur, the flowers being either yellow or white. Usually one 

 color predominates in each locality. Hybrids of these color forms, as demonstrated 

 by Dr. E. W. Lindstrom, are sterile, which raises the question whether or not 

 these forms are genetically and specifically distinct.
