Judged by the strikingly different aspect of the specimens from western Louisiana

 mens from Mobile differ from the Western form only by the finer and more close 

 pubescence of the stem. Closely connected by Intel-grading forms with the type. 



Type locality : "\V. Louisiana and Texas, ])rummond, Leai'enworth, Hale."
