Packera sanguisorboides
Packera werneriifolia
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.

Packera werneriifolia is morphologically variable; it occurs throughout the central Rockies and, sporadically, as far west as the Sierra Nevada. Leaf morphology varies from ovate, elliptic, or narrowly elliptic in the Rockies to narrow with revolute margins in California and Arizona. All specimens are characteristically scapiform.
