recognize some very good species which he described. In this case he 

 consigned Scheele's plant to synonomy, making it equal to Petalostemon 

 violaceus var. pubescens A. Gray, a variety which was never published, 

 and according to Gray's own statement, has no characters to separate it 

 from the species, except more pubescence on the calyx. In one of the 

 works, I think either PL Wright, or PL FendL, I came across a reference 

 to Scheele's species, which led me to think that my plant might be the 

 same. Upon referring to the original description in Linnaea, it became 

 evident that Petalostemon virgatum, which name, however, was used 

 previously by Nees, is an excellent species, and agrees in all essential 

 points with my specimens. New Braunfels, his type locality, is some 

 sixty or seventy miles southeast of Kerrville, but the character of the 

 country is the same. The plant can be distinguished from K. purpurea 

 (violaceus} at a glance.
