Packera sanguisorboides
Packera franciscana
Packera sanguisorboides is known from the San Juan and Sangre de Cristo mountains of northern New Mexico, the Magdalena Mountains of western New Mexico, and the Sacramento Mountains of southern Lincoln and Otero counties. It may have affinities with P. coahuilensis Greenman.

Of conservation concern.
Packera franciscana is known only from above timberline in the San Francisco Peaks and is in the Center for Plant Conservation’s National Collection of Endangered Plants. It spreads by extensive rhizomes and is fairly abundant locally.
