Zamia wallisii is a species of plant in the family (Zamiaceae) that is commonly known as the chigua.

Zamia wallisii was described in 1875 by Alexander Braun from material collected by Gustav Wallis in Colombia.

Both the Wallis and Kalbreyer collections were lost and no type specimen was extant resulting in some doubt about the existence of the species until its rediscovery in the 1980s, by Ian Sutherland Turner.

[2] Its most noteworthy feature is its leaflets, which are up to 23.5 inches (60 centimeters) long and eleven inches (26.5 centimeters) wide, the largest of any gymnosperm.

[1] Plants are found near the town of Frontino, Antioquia Department, and also near Urrao, and in Las Orquideas National Park.
