I'lmropsis praelongus Rydb. Colo. Agr. Exp. Sta. Bull. 100: 20G. 190G. 



Type locality: "Near St. Thomas, S. E. Nevada, at the confluence of the Muddy 

 River with tho Virgen." 



Range: Colorado and Utah to Nevada and New Mexico. 



New Mexico: Fort Wingate; Carrizo Mountains; Acoma; hills near Santa Fe; 

 Kiln Quemado; San Augustine Plains; Lemitar; Roswell. Upper Sonoran Zone. 



The three following specimens are doubtfully placed here; they are not sufficient ly 

 distinct t<> bo separated by name. The pods are slightly smaller as are the leaves, 

 the plants probably being starvelings: Albuquerque, June, 1881, Vasey; near Carri- 

 zozo, July 22, 1901, Wooton; near Camp City, April, 1910, Wooton. 



This and the following species are coarse ill-snielling 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.
