In Arizona specimens the leaflets are only 3 to 4 mm. long and vary 

 from acutish to truncate at apex, whereas in the type of the species 

 they are mostly longer and vary from obtuse to very acute and 

 cuspidate.

This plant is easily recognized by its conspicuously brown-mottled 

 pods, narrow leaflets, and habit of spreading by slender creeping root- 

 stocks. The pods are usually much-inflated, but a form with narrow 

 pods (A pictus var. angustus M. E. Jones) also occurs in Arizona. 

 About as common in this State and occupying the same region as 

 the typical form of A. ceramicus is var. imperfectus Sheldon (Phaca 

 longifolia (Pursh) Nutt.). This has not more than 6, often no lateral 

 leaflets and the terminal leaflet is represented by a prolongation of the 

 rachis, whereas, in typical A. ceramicus, the lateral leaflets are 4 to 

 14 and the terminal one has a distinct, although sometimes very 

 narrow blade. The sweet roots of A. ceramicus are eaten in spring 

 by Hopi Indian children.
