- Comments
- In the Watershed, collection of Artemisia ludoviciana has been more common from the Cristos than from the south San Juans, but it is present in all regions. The species is quite variable. In the Watershed, two subspecies predominate: subsp. ludoviciana and subsp. incompta. Subsp. mexicana is vouchered once (1924) from the Watershed, from the Chama basin (listed incorrectly as "Costilla Co"). Artemisia ludoviciana occupies a wide range of elevations and habitats, including disturbed ground, and is one of the few flowers recorded from every county in Colorado. Its native distribution in the USA is Western states, the Plains, and upper Midwest. It is adventive in all other states except for West Virginia, and follows the Rio Grande drainage through New Mexico and on down to within 50 miles of the Gulf of Mexico. Note that "ludoviciana" refers not to the state of Louisiana but to the Louisiana Territory as defined in 1812, which includes all of the present state of Colorado.
