Discussion

Of conservation concern.

Variety toumeyi is known only from the Pinal, Chiricahua, and Santa Catalina mountains of Arizona and the Animas and Black mountains of New Mexico. Although range and habitat of var. toumeyi overlap with those of var. neomexicana, the two are readily distinguished. Adaxial leaf faces of var. toumeyi are glabrate and the plants are scapiform.
