Lastarriea chilcnsis Ki'iny. 



lominnii nil dry iiicsus and slopes, but not in cultivated grounds. This is one 

 of a group ol plants common to Chile and California, whose status as indigenes or 

 aliens has occasioned some diflerence of opinion among botanists. The weight oi 

 opinion favors its retention among the natives; but the most recent authority in- 

 dicates it as "naturalized from Cliile."'"
