The species does not seem to be sufficiently distinct (judging merely from dried 

 material and descriptions) from A. pephragmenus M. E. Jones, but we hesitate to 

 change the name without a-field knowledge of the two plants. In all the New Mex- 

 ican material the pods are not glabrous but puberulent.
