Abstract
In checking specimens of Liatris Schreb. from the herbaria of Dr. Chas. C. Deam and of Butler University, it was found that a considerable degree of confusion and uncertainty has existed with regard to the classification of these plants. This was to be expected, since this genus is one of unusual complexity with many variables and intergradations existing among the various species. Some attempts at classification have been somewhat superficial, placing a number of different types under one species name, while others have drawn the line too closely and made separate species and varieties out of plants which were merely mutations or impoverished individuals.
