The typical form of the species, with linear entire 1 -nerved leaves, 

 and var. leptophylloides (Murr) Thellung und Aellen (C. pratericola 

 Rydb.) with oblong or oblong-lanceolate leaves, the lower ones 3-nerved 

 and subhastately toothed, are both common in Arizona. They are 

 usually tall and only moderately farinose. The var. desiccatum (A. 

 Nels.) Aellen (C. desiccatum A. Nels.), is known in Arizona only by a 

 collection in Apache County (Griffiths 5832). It is a lower, more 

 diffusely branched, copiously farinose plant.
