Discussion
Variety neomexicana is known from throughout Arizona and in southern and western New Mexico. Its persistent, heavy tomentum and well-developed cauline leaves make it easy to recognize. If type of Senecio thurberi A. Gray belongs within circumscription of Packera neomexicana (see T. M. Barkley 1978), a new combination in Packera will be necessary.
