THE RANGE OF AMORPHA FRUTICOSA. 
By Joun M. HouzincEr. 
Amorpha fruticosa occurs in the eastern and southern 
United States, ranging westward to the Rocky Mountains, 
‘northeastward to British America,” south and southwestward 
into Texas, Mexico, and southern California. Its occurrence 
in Mexico is attested by Pringle’s plant collected in 1887 in 
the state of Chihuahua, distributed under No. 1221. Coulter’s 
Botany of Western Texas credits the species to that state, as 
“apparently throughout Texas.” There are in the National 
Herbarium at least two plants to substantiate this extension 
of range: the Mexican Boundary Survey plant, No. 248, from 
Southern Texas, and Elihu Hall’s No. 128 from eastern 
Texas. These two plants had been wrongly referred to 
A. levigata, Nutt., which also occurs in Texas. ‘Two other 
specimens from the same state, Hall No. 127, and Lind- 
heirmer No. 595, are in the National Herbarium, referred to 
the variety angustifolia of this species. But the difference 
between the type of the species and the variety is merely one 
of width of leaves. These vary considerably on the same bush; 
and after glancing over a series of specimens, one feels 
strongly dissuaded from holding to the variety. In fact, the 
four Texas specimens mentioned above are preferably 
referred to the type of the species, not the variety. 
Amorpha fruticosa also occurs in Arizona, as is shown by 
the following specimens: 
Dr. Smart’s plant, No. 314, from Prescott. 
Dr. Rothrock’s plant from Willow Spring.’ 
Pringle’s, from the Santa Rita Mts. 
Lemmon’s, from the Huachuca Mts. 
Dr. Palmer’s No. 484, from Willow Spring. 
M. Dougal’s plant, from central Arizona. 
The only fruiting specimen among these is Lemmon’s, 
which shows, by its glabrous legumes (though they are 4

possibly referable to 4. Californica.
