Zamia manicata is a species of plant in the family Zamiaceae. It is found in Colombia (Choco Department and Antioquia Department) and Panama (Darien Province). Its natural habitat is subtropical or tropical moist lowland forests.
The stem is subterranean, rounded to sub-cylindrical, 5 to 10 centimetres (2.0 to 3.9 in) in diameter. The three to ten compound-leaves on each plant are 0.5 to 2 metres (1 ft 8 in to 6 ft 7 in) long, with a 0.2 to 1 metre (7.9 in to 3 ft 3.4 in) long petiole (stalk). The stalk is lightly to very heavily covered with prickles, which may extend into the lower third of the leaf axis. Leaflets are oblong to long-elliptic, toothed along the outer third of their margins, and 15 to 35 centimetres (5.9 to 13.8 in) long and 3 to 7 centimetres (1.2 to 2.8 in) wide in the middle of the leaf. Leaflets are attached to the leaf axis by a petiolule (a short petiole) with a gland-like collar at the base, a feature unique among cycads.[2]
Like all Zamias, Z. manicata is dioecious, with each plant being either male or female. Male strobili (cones) are cylindrical, 4 to 6 centimetres (1.6 to 2.4 in) long and 1 to 1.5 centimetres (0.39 to 0.59 in) in diameter, cream to tan in color, and stand on 15 to 30 centimetres (5.9 to 11.8 in) long peduncles (stalks). Female cones are cylindrical to ovoid-cylindrical, 10 to 15 centimetres (3.9 to 5.9 in) long and 4 to 7 centimetres (1.6 to 2.8 in) in diameter, and wine-red to dark red-brown in color. Seeds are 1 to 1.5 centimetres (0.39 to 0.59 in) long and 0.5 to 0.8 centimetres (0.20 to 0.31 in) in diameter.[3]
Habitat
Z. manicata grows between 100 and 1,000 metres (330 and 3,280 ft) in rain forest, secondary forest, coffee plantations, and on the edges of pastures. It is found in Darien Province in Panama and adjacent Colombia.[2]
