Range: Southern New Mexico to Chihuahua. 



New Mexico: Mesilla (Wooton 35). Sandy fields, in the Lower Sonoran Zone. 



In the original description Doctor Watson saj^s the plant is erect and branching, a 

 statement in which he is probably wrong. Dalea orenaria Jones, ^ is doubtless very 

 near this species, as the author suggests. Our plant has the jirostrate, matlike habit 

 of D. arenaria and grows on the sands, but is certainly perennial and the bracts are 

 very different.
