"This distinctive species is readily recognised by its large leaves and broad, thin-textured to almost papery or translucent leaflets which taper to the base and have wavy margins" (Jones 1993).
Mexico: Veracruz, "near the Oaxaca border at about 120 m altitude, growing in wet, tropical evergreen rainforest. ... This species ... is known from only about thirty plants, and precise locality details were not presented in the original publication in an attempt to protect the species in the wild from extinction by collectons" (Jones 1993).
Although potentially useful as an ornamental, "[t]his species is rare in cultivation and experience is limited. With its large attractive leaves this is one of the most distinctive species of Ceratozamia" (Jones 1993).
Seattle's Volunteer Park Conservatory has one.
The epithet euryphyllidia means "with broad leaflets."
