Zamia amplifolia is a species of plant in the family Zamiaceae.[2][3] It is endemic to the Calima River watershed of Valle del Cauca Department, Colombia.[4][5][6]
Zamia amplifolia is a bush or small tree, with a stem up to 2.5 metres (8 ft 2 in) tall. There are three to six leaves on a plant, 1 to 2 metres (3 ft 3 in to 6 ft 7 in) long, with a 0.5 to 1 metre (1 ft 8 in to 3 ft 3 in) long petiole (stalk). The stalk is covered with prickles, which may extend into the lower third of the leaf axis. There are six to ten leaflets, which are elliptical, pointed at the ends and with smooth edges. Leaflets in the middle of the leaf are 30 to 50 centimetres (12 to 20 in) long and 12 to 15 centimetres (4.7 to 5.9 in) wide. The specific name amplifolia technically refers to the size of the leaves, but was intended to refer to the very large leaflets.[7]
Like all Zamias, Z. amplifolia is dioecious, with each plant being either male or female. Male strobili (cones) are cylindrical to elongate-cylindrical, 8 to 12 centimetres (3.1 to 4.7 in) long and 1 to 2 centimetres (0.39 to 0.79 in) in diameter, and cream to tan in color. Female cones are ovoid to ovoid-cylindrical, 20 to 40 centimetres (7.9 to 15.7 in) long and 8 to 12 centimetres (3.1 to 4.7 in) in diameter, brown in color, and stand on shortpeduncles (stalks). Seeds are ovoid, 1.5 to 2.5 centimetres (0.59 to 0.98 in) in diameter, and have a red sarcotesta (outer fleshy coat).[8]
