 species, but they fit the original description more nearly than any other material 

 we have seen. Most of the material passing under this name in herbaria belongs 

 elsewhere.

This species is generally confused with A. urightii, which it resembles in habit; 

 but its leaflets are arranged pinnately upon a short rachis and have a short petiole, 

 and the flowers have long peduncles.

 ters will separate it from the former and the pubescence distinguishes it at once from 

 the latter.
