family, it is easy to credit this; but it is more difficult to realize 
that in the obscurely flowered and unattractive Chenopodiacee 
and Amaranthacez their faculties of observation have guided them 
as safely. In the section of the Navajo country where I did 
most of my collecting there are two species of Chenopodium so— 
_ much alike that white people in general do not distinguish them 
from one another but call them all “lamb’s quarter.” Thereis 
still another so little like its congeners in its macroscopic charac- 
ters that none, I imagine, but the scientific could trace the 
_ relationship; this is the Chenopodium, or Teloxys cornutum ; when 
_ burned it emits a fine aromatic odor, and in the late autumn it 
changes toa rich rose-lake color which lends a beautiful tint to 
_ the slopes of the Zuñi mountains. Again the relationship be- 
tween the goosefoot and amaranth families is not known to the 
unscientific among ourselves. That the Navajos have traced 
some character in common, in these instances, is evident from the 
following names : 
Chenopodium Sremontii, tlotahi. 
_ Chenopodium album, tiotéhi-tso, or “ great tlotaht.” 
Teloxys cornutum, tsinya tlotahi, or “ tlotahi under the trees,” 
from its sub-arboreal habitat. 
$ _Amaranthus retrofiexus, tlotahi-hochi, or “ a tlotahi.” 
_ They do not however apply the name “ofd/i to all the Cheno- 
aceæ, but they evidently connect the not very similar genera 
of Atriplex and Sarcobatus, the former being called togoji, refer- 
ng to its spines, and the latter éogosijin, or “ black toggyi.”
