The reddish-brown stalk is covered with prickles, which extend into the lower third of the leaf axis. There are 10 to 30 leaflets, which are oblong-lanceolate to lanceolate, pointed at the ends and toothed along the edges of the outer half of the leaflet. Leaflets in the middle of the leaf are 15 to 20 cm long and 2 to 4 cm wide.

Male strobili (cones) are cylindrical, 6 to 10 cm long and 1 to 2 cm in diameter, brown in color, and stand on 8 to 15 cm long peduncles (stalks). Female cones are 10 to 15 cm long and 3 to 5 cm in diameter, dark red-brown in colored, and stand on 5 to 8 cm long stalks. Seeds are ovoid, 1 cm long and 0.5 cm in diameter, with a red sarcotesta (outer fleshy coat).
Habitat
Zamia amazonum is locally abundant in the upper Amazon basin in Brazil, Colombia, Peru, and Venezuela, and in Chocó Department on the Pacific coast of Colombia. The species name refers to its wide-spread occurrence in the Amazon basin.
