Taxonomic Etymology:
A sand-dwelling lizard associated with desert broom plants or dune scrub.
Uma — An arbitrary name coined by Baird in 1859, possibly derived from Native American sources or used for its brevity. Its etymological origin remains unclear.
scoparia — From Latin scoparius, “broom-like” or “of the broom plant.” Possibly refers to the plant genus Scoparia or to desert vegetation typical of its habitat.
