Clammyweed is not limited in its range to desert areas, but is found as
far north as Saskatchewan and British Columbia. However, it is also a
common annual in Texas, New Mexico, and Arizona at elevations between
1,200 and 6,000 feet, and is usually found in abundance in the sandy
channels of dry stream beds.
It somewhat resembles both Yellow Beeweed (_Cleome lutea_) and
Jackass-clover (_Wislizenia refracta_.)
