Discussion | 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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Packera tomentosa is common throughout most of its range. The basal and proximal cauline leaves are held at about 45 degrees to the stems. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
