Dioon tomasellii is a species of cycad in the family Zamiaceae. It is endemic to Mexico, where it occurs in the states of Durango, Guerrero, Jalisco, Michoacán, and Nayarit.[1]
This plant grows in oak and pine-oak forest and woodland habitat. Threats to the species include destruction of the habitat for agriculture and overcollection for horticultural purposes.[1]
This species was first described in 1984.[2] It was revised in 1997, with one variety being elevated to species status as Dioon sonorense.[3]
Mutualism
The beetle Pharaxonotha novoia is in an obligatory mutualistic relationship with Dioon tomaselli, living and breeding in male cones and consuming pollen and cone tissues while serving as a pollinating vector by transferring pollen to female cones.[4]
