Frison says: “Robertson (1891, 1894, and 1896), in Illinois, 
records males and females of etc.” Here “Illinois” means “Car- 
linville.” Only 3 of the flowers mentioned showed both sexes. 
Frison follows Lutz and Cockerell in overlooking most of the 
Botanical Gazette papers and “Labiatse” as well as Knuth’s 
work.
