Somewhat intermediate between the var. intermedia and var. hispida are the 

 collections of Vareschi & Foldats 4730, Steyermark 90389, and Car dona 227 A, 

 in which the leaves are glabrate or sparsely ciliate or sparsely hispidulous. 

 Steyermark 59383 intergrades somewhat with var. densipila, but the pubescence 

 is shorter and the leaves narrower and more erect -ascending than in var. densipila.
