The three following specimens are doubtfully placed here; they are not sufficiently 
distinct to be separated by name. The pods are slightly smaller as are the leaves, 
the plants probably being starvelings: Albuquerque, June, 1881, Vasey; near Carri- 
z0z0, July 22, 1901, Wooton; near Camp City, April, 1910, Wooton. 
This and the following species are coarse ill-smelling plants of the open plains and 
valleys at middle and lower elevations. The separation of the species rests more on 
geographical distribution than on characters, though the plant which lives in the drier 
and hotter area is glabrous. Mr, Jones may be right when he recognizes A. praelongus 
as merely a subspecies of A. pattersoni. The two are said to be poisonous, but we 
have never seen any evidence of their being eaten by stock.
