Global Range: At present puzzle sunflower occurs in two general areas in Pecos and Reeves Counties in west Texas and four general areas in New Mexico. Historically there were six other locations within Pecos and Reeves Counties; however all except one of these sites have not been relocated due to imprecise locality data and the lack of access to private land. The relocated site was heavily invaded by salt cedar and had little water left. No puzzle sunflowers were found, although the entire site was not searched.
