Sceloporus undulatus

The most widespread and variable Sceloporus in New Mexico. Infraspecific taxonomy is somewhat uncertain, and Sceloporus undulatus has been split into several species based on mitochondrial lineages by Dr. Leaché of the University of Washington. However, these "species" apparently interbreed & do not correspond with morphological variation.
