Discussion

Packera tampicana is fairly widespread along the Gulf Coastal Plain and north and in Mexico. Morphologically, P. tampicana most closely resembles P. glabella; the former grows in very wet, sandy or clay soils and open sunlight, the latter grows in drier habitats, usually in partial shade.

Packera clevelandii is known only from the North Coast Ranges and foothills of the Sierra Nevada on serpentine soils in chaparral communities. It is the only Packera with subsucculent, glaucous herbage.
