In the flora area, Bernardia myricifolia is known from southern Texas, with a single outlying collection from Brewster County [H. B Parks 1724 (MO); B. L. Turner et al. 2003]. Reports of B. myricifolia from Arizona and California are based on plants identified here as B. incana. Reports of B. myricifolia from New Mexico are based on specimens of B. obovata. In Mexico, B. myricifolia is most abundant in thornscrub in the northeast to montane areas of the Chihuahuan Desert.
