STANDLEY : CHENOPODIACEAE 417 
American material has been referred to it by European writers. 
It has been confused with C. album, to which it is very closely 
related, differing chiefly in the deeply lobed blades of the upper 
leaves, and the dull rather than lustrous seeds: It is widely dis- 
tributed in the Southwest. Some of the numerous collections at 
hand are cited below.

This is known definitely to occur in Siberia, but whether it is 
found in North America is still doubtful. It has been reported 
from Alaska and Mexico, and it is reasonable to expect it in 
Alaska, although none of the numerous collectors who have visited 
that region in recent years have found it. The occurrence of the 
species in Mexico seems very doubtful. The plant is so distinct 
that it scarcely seems probable that any other species would be 
mistaken for it. There is always the possibility of a misplaced 
label as an explanation of an otherwise inexplicable extension of 
range.

Chenopodium incisum has a wide range, extending from south- 
ern Colorado, through Mexico and Central America, to South 
America, besides occurring in Africa. Probably it should be 
known as C. graveolens Lag. & Rodr., but the data afforded by the 
original publication of that species are insufficient for certainty. 
The plant of the United States has been known generally as C.
