434 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
RanGeE: Colorado to western Texas and northeastern Mexico. 
New Mexico: Common nearly throughout the State except in the higher moun- 
tains. Dry hills and plains, in the Lower and Upper Sonoran zones. 
So far as we are able to judge from field observations, the plants of the western and 
southwestern sections of the State agree very well with the plants about Santa Fe. 
The plant found in the south-central part of the State appears somewhat different 
when growing, but we are unable to find characters to separate the two. The Santa 
Fe plant has rather bright yellow flowers which open only just before sundown, and 
the plant is rather widely spreading and, when full grown, almost 1 meter high; while 
the plant of the Rio Grande Valley, at the south end of the State, is generally lower, 
about 60 cm. high or less, its flowers pale yellow, fading almost white, and opening 
early in the afternoon, not infrequently by 2 or 3 o’clock.
