STANDLEY: CHENOPODIACEAE 415 
CHENOPODIUM PRINGLEI Standley, N. Amer. Fl. 21: 18.. 
| 1916 
Allied to C. Fremonti S. Wats., to which the specimens have 
been referred, but distinguished by the form of the leaf blades, 
which are coarsely sinuate-dentate and only slightly lobed. In 
C. Fremonti the well-developed lobes are usually entire, at least 
the large terminal one. The type of C. Pringlet was collected near . 
Dubl4n, Hidalgo, Mexico (Pringle 9283). Pringle’s No. 6570 
from Tule, Hidalgo, is the same species. 
CHENOPODIUM NEOMEXICANUM Standley, N. Amer. FI. 21: 19. 
1916 
Related to C. Fremonti S. Wats., but differing in the adherent 
pericarp. The type was collected along Mineral Creek, Sierra 
County, New Mexico, by O. B. Metcalfe (No. 1413), and the 
species has been collected in the Chiricahua Mountains of Arizona 
_by J. C. Blumer (No. 1409). 
CHENOPODIUM ARIZONICUM Standley, N. Amer. Fl. 21: 19. 
1916 
A segregate from C. Fremonti, distinguished primarily by having 
the pericarp adherent to the seed. It is distinct from C. neo- 
mexicanum in the size of the seed, scarcely more than half as large 
as in the latter. The following specimens have been seen: 
Arizona: Santa Rita Forest Reserve, Griffiths 5982 (type); 
Santa Rita Mountains, Griffiths 6o11; near Tucson, 1911, Wooton; 
Rincon Mountains, Blumer 3585. 
CHENOPODIUM AMARANTICOLOR Coste & Reynier, Bull. Soc. Bot. 
France 54: 181. 1907 
A species not reported previously from North America. It 
is a relative of C. album L., from which it is distinguished by its 
broad leaf blades and the red coloration of the upper leaves and 
inflorescence. Specimens from Thomasville, Georgia (EZ. B. 
Taylor, 1909) and Santiago de las Vegas, Cuba (Abarca 2794), 
are referred here. The native habitat of the plant is not known, 
but it has been found as a weed in France. It is sometimes culti- 
vated as a foliage plant.
