This needless and confusing change should have been provided 
against in the list of nomina conservanda, and it is to be hoped that 
the oversight may be remedied in a future revision. 
Distribution 
Mexico is the center of distribution of the genus, fully 120 species 
(119, Conzatt1) having been described from the temperate regions 
of that republic. Thence it extends along the Andes to Chile, 
where it has. its southernmost representative in Dalea multifoliata, 
at 30° south latitude. Crossing the United States’ boundary, it 
is well developed in the Lower Sonoran life-area; 17 species are 
found in Texas (CouLTER), 19 in New Mexico (Hammonp), and 
33 in Arizona (THORNBER). The most northern species is Parosela 
alopecuroides, which reaches southeastern North Dakota, at 
latitude 30° N., and the same species extends east to Tennessee 
(GATTINGER). Besides the continental species, two outlying ones 
are found on the Galapagos Islands. In California it is a char- 
acteristic genus of the deserts, a single species passing into an arid 
border of the cismontane region.
