CHENOPODIUM VIRIDE L. Sp. Pl. 219. 1753 
Chenopodium opulifolium Schrad.; Koch & Ziz, Cat. Pl. Palat. 6. 
1814. 
This is a well-known Old World species which generally has been 
known as C. opulifolium. C. viride L., however, was based upon 
a plate which evidently represents the same plant. The Linnaean 
‘name has been applied usually to the plant which is properly 
known as C. paganum Reichenb. So far as the writer knows, 
C. viride, in the sense in which the name is used here, has never 
been reported from North America, but the rather numerous 
collections cited below should all be referred to it. It differs 
from C. album, with which American specimens have been con- 
fused, in having the blades of the lower leaves as broad as long 
and, when dry at least, of a peculiar bluish-green color.

CHENOPODIUM DACOTICUM Standley, N. Amer. Fl. 21: 22. 1916 
This species is related to C. album and C. ferulatum Lunell, but 
appears sufficiently distinct in the very coarse, loose pubescence, 
ill-scented foliage, and coarsely punctate seeds. The following 
specimens are in the National Herbarium: 
SoutH Dakota: Cedar Pass, Over 6175 (type); Fall River 
Falls, Rydberg 964; Talus slopes, badlands, Washington County, 
August 4, 1914, Over; summit of Sheep Mountain, Pennington 
County, August 20, 1914, Over; badlands near White River, August 
I, 1914, Over; White River, Over Garr. . 
The same plant apparently, doubtless adventive, has been 
collected in waste ground at Courtney and Sheffield, Missouri, 
by B. F. Bush (Nos. 7058A, 7066). 
CHENOPODIUM PETIOLARE H. B. K. Nov. Gen. & Sp. 2: 191. 1817 
North American botanists have overlooked this species, but in 
Europe it has been generally recognized in recent years, and North
