A NEW SPECIES OF CERATOZAMIA (ZAMIACEAE) FROM VERACRUZ, MEXICO

Ceratozamia morettii is described from a cloud-forest environment in V eracruz, Mexico. The main morphological characters are illustrated, an d comments on related species are made. The new species differs from o thers in the genus by the near prostrate habit, circinate vernation of the leaves, and wide leaflets with translucent venation. This taxon i s apparently related to a group of species that are relatively small t runked, branched, produce few leaves, and have relatively small strobi li. The non-sympatric species of the group also inhabit moist to very moist habitats, as in the case of C. miqueliana, C. microstrobila, and C. mexicana var. robusta.
