État de la populationExpert
The known distribution of Ceratozamia mexicana has been constantly revised in response to ongoing changes in taxonomy since its original publication in 1846. The identity of this binomial was ambiguous for several decades. Originally five closely related species were described but Miquel collapsed all five species into synonymy with C. mexicana. Half a century later, Schuster (1932) circumscribed the genus to include only two species: Ceratozamia kuesteriana and C. mexicana, with two varieties and two forms. However, in the first modern taxonomic treatment (Vovides et al. 1983) and continuing with the typification of names within the genus (Stevenson and Sabato 1986), the type species was circumscribed to the central region of Veracruz. In this context, Vovides et al. (1983) attributed a wide geographic distribution and high variation of morphological characters to C. mexicana while recognising three varieties: C. mexicana var. mexicana, C. mexicana var. latifolia Schuster and C. mexicana var. robusta Dyer. Martínez-Domínguez et al. (2018) recognized fourteen species of Ceratozamia with a narrower circumscription of C. mexicana. The newly circumscribed taxon has experienced a loss of habitat estimated as 83% over the past three generations.

Description complète des menacesExpert
The mountain cloud forest habitat is threatened by habitat destruction. Forest is cleared for agriculture (coffee, banana and corn) and cattle farming. The species' habitat is also impacted by the removal of wood for charcoal production. In 1992 a community nursery was established specifically for the sustainable production of Ceratozamia mexicana.
