There has been much uncertainty about this species, largely because Doctor Gray 

 confused it originally with what he afterwards described as A. greenei. The true 

 Astragalus fendleri is most closely related to A. flexuosus and A. hallii. Its pods are 

 larger at the distal end and taper at the base, being almost intermediate between the 

 small terete pod of A. flexuosus and the considerably larger terete pod of A. hallii, 

 but not stipitate nor inflated as in J., greenei. The plant was originally described as 

 being "a foot high."
