There has been much uncertainty about this species, largely because Doctor Gray 
confused it originally with what he afterwards described as A. greeneit. The true 
Astragalus fendleri is most closely related to A. flexruosus 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. flerwosus and the considerably larger terete pod of A. hallii, 
but not stipitate nor inflated as in A. greenei. The plant was originally described as 
being ‘‘a foot high.’’
