Zamia manicata
Subtropical or tropical moist lowland forests, rain forest, secondary forest, coffee plantations, and on the edges of pastures.·Subterranean stem
Zamia manicata is a species of cycad native to the rainforests of Colombia and Panama. It is characterized by its subterranean stem and distinctive leaves with leaflets that have a unique gland-like collar at their base. This species plays a role in the "Manicata clade," a group of related cycads found in northern Colombia.

About Zamia manicata
Zamia manicata is a species of cycad belonging to the Zamiaceae family, primarily found in the subtropical and tropical moist lowland forests of Colombia and Panama. Its natural distribution spans the Choco and Antioquia Departments in Colombia, and the Darien Province in Panama. This species is known for its distinctive botanical features, including a subterranean, rounded to sub-cylindrical stem that typically measures between 5 to 10 centimeters in diameter.
The leaves of Zamia manicata are compound and can grow to impressive lengths, ranging from 0.5 to 2 meters. The petiole, or stalk, which supports these leaves, can be between 0.2 to 1 meter long and is often adorned with prickles. A particularly unique characteristic of this cycad is the presence of a gland-like collar at the base of each leaflet, a feature that sets it apart from many other cycad species. The leaflets themselves are oblong to long-elliptic, measuring 15 to 35 centimeters in length and 3 to 7 centimeters in width, and possess toothed margins on their outer third.
As with all species of Zamia, Zamia manicata is dioecious, meaning individual plants are either male or female. The reproductive structures, or cones, differ between the sexes. Male cones are cylindrical, measuring 4 to 6 centimeters in length, and are typically cream to tan in color, borne on peduncles up to 30 centimeters long. Female cones are larger, generally cylindrical to ovoid-cylindrical, ranging from 10 to 15 centimeters in length, and display colors from wine-red to dark red-brown. The seeds are small, about 1 to 1.5 centimeters long.
Zamia manicata grows in various forest types, including primary and secondary rainforests, as well as in more disturbed areas like coffee plantations and the edges of pastures, typically at elevations between 100 and 1,000 meters. The species has faced taxonomic confusion, having been previously synonymized with Zamia obliqua, from which it differs in stem habit, leaflet size, and cone morphology. Zamia manicata is also significant as the namesake for the "Manicata clade," a group of related cycad species found in northern Colombia.

Frequently Asked Questions
Where is Zamia manicata found in the wild?
Zamia manicata is naturally found in the Darien Province of Panama and adjacent regions of Colombia, specifically in the Choco and Antioquia Departments.
What are the key botanical features of Zamia manicata?
This cycad has a subterranean stem and compound leaves that can be quite long, up to 2 meters. A notable characteristic is the gland-like collar at the base of each leaflet, which is unique among cycads.
What do the cones of Zamia manicata look like?
Male cones are cylindrical, cream to tan in color, and relatively small. Female cones are larger, cylindrical to ovoid-cylindrical, and range in color from wine-red to dark red-brown.
What is the "Manicata clade"?
The "Manicata clade" is a group of several species of Zamia plants that are found in northern Colombia. Zamia manicata is the namesake for this group, highlighting its significance within this regional classification.
How does Zamia manicata differ from Zamia obliqua?
Zamia obliqua typically has a tall, upright stem, shorter leaflets, male cones on much shorter stalks, and lighter-colored female cones, distinguishing it from the subterranean-stemmed Zamia manicata.
