Comments

In the Watershed, MacDougal's verbena grows in foothill and lower-montane dry meadows and canyon slopes, often found also in disturbed ground, by road edges and irrigation ditches. The Lower Basin record was from the Conejos River floodplain. Ackerfield (2015) shows Alamosa Co, with no vouchers in SEINet. The west-side Watershed records are toward the northern end of the USA distribution. Note that Allred et al. (2020) describe Verbena macdougalii as "eglandular" yet Ackerfield cites its glandular calyces as a character to distinguish it from V. stricta. In New Mexico V. macdougalii follows the Rio Grande drainage to the Mexican border, but no farther down river.
