Zamia chigua

Zamia chigua is a species of cycad native to the Choco Department of Colombia and Chiriquí Province of Panama. It thrives in moist lowland tropical and subtropical forests, characterized by its shrub-like to small tree growth form with a wrinkled stem topped by compound leaves. This dioecious species produces distinct male and female cones, and its seeds are notable for their red sarcotesta.

Etymology
The specific name 'chigua' is derived from the common name for cycads used by indigenous peoples in Choco Province.

About Zamia chigua

Zamia chigua is a species of cycad belonging to the Zamiaceae family. It is distinguished by its growth habit as a shrub or small tree, typically featuring a wrinkled stem that can ascend to approximately 2 meters in height. The plant is adorned with a crown of compound leaves at the stem's apex, each leaf comprising numerous long, lanceolate leaflets with smooth margins. The common name 'chigua' originates from the indigenous peoples of Choco Province, Colombia, where the species is found.

Botanical Description

The stem of Zamia chigua is notable for its wrinkled texture and can reach up to 2 meters (6 ft 7 in) in height and 15 centimeters (5.9 in) in diameter. The compound leaves range from 0.5 to 3 meters (1 ft 8 in to 9 ft 10 in) in length, supported by a petiole or stalk that can extend up to 1 meter (3 ft 3 in) and is densely covered with prickles. Each leaf contains between 30 and 80 leaflets, with those in the central part of the leaf measuring 10 to 30 centimeters (3.9 to 11.8 in) long and 1 to 1.5 centimeters (0.39 to 0.59 in) wide. As with all members of the Zamia genus, Zamia chigua is dioecious, meaning that individual plants are either male or female.

Reproduction

Reproductive structures in Zamia chigua are cones. Male cones, known as strobili, are cylindrical, measuring 10 to 20 centimeters (3.9 to 7.9 in) in length and 2 to 3 centimeters (0.79 to 1.18 in) in diameter, and present in a cream to light-yellow hue. The female cones are larger, described as narrow-ovoid to cylindrical, with lengths of 20 to 30 centimeters (7.9 to 11.8 in) and diameters of 8 to 12 centimeters (3.1 to 4.7 in), exhibiting a tan to light brown coloration. The seeds are ovoid and possess a distinct red sarcotesta, which is the fleshy outer layer.

Distribution and Habitat

Zamia chigua is found in the Choco Department of Colombia and the Chiriquí Province of Panama. It thrives in subtropical or tropical moist lowland forest environments. While it is common in Chiriquí Province at elevations between 600 to 1,200 meters (2,000 to 3,900 ft), it is also present in the lowland rainforests of Choco Department. There is an indication that it may also grow on mountain slopes in Darien Province, Panama, and adjacent Colombian regions, though it had not been documented there as of 2004.

Conservation

The primary threat to the survival of Zamia chigua is habitat destruction. This loss of its natural environment poses the most significant challenge to the species' continued existence in its native range.
