Encephalartos laevifolius is a critically endangered cycad species native to South Africa and Eswatini. It is a tree-like plant that can grow up to 3.5 meters tall, characterized by its pinnate leaves with smooth-edged, leathery leaflets. This dioecious species produces distinct male and female cones, and its seeds are covered in a sarcotesta.

Facing Extinction In the Wild
About Encephalartos laevifolius
Encephalartos laevifolius is a species of cycad characterized by its tree-like growth form and is native to southeastern Africa. It is found naturally in the KwaZulu-Natal, Mpumalanga, and Limpopo provinces of South Africa, as well as in the vicinity of Piggs Peak in Eswatini. Despite its natural distribution, the species is facing a severe threat of extinction in the wild, leading to its classification as critically endangered by the IUCN as of 2012.
Botanical Description
This cycad can reach heights of up to 3.5 meters, with a sturdy stem that measures between 25 and 35 cm in diameter. It exhibits a tendency to develop additional stems from basal suckers. The pinnate leaves are a significant feature, growing up to 1 meter in length and supported by a petiole of 22-25 cm. Each leaf is comprised of numerous pairs of lanceolate leaflets that are leathery in texture, measuring 12-15 cm long. These leaflets are distinguished by their smooth edges and terminate in a sharp tip.
Reproduction
Encephalartos laevifolius is a dioecious species, meaning individual plants are either male or female. Male plants produce one to five cylindrical-fusiform cones, which can range from 30 to 40 cm in length and 9 to 10 cm in width, typically displaying yellow to brown coloration. Female plants also bear one to five cones, but these are generally cylindrical, measuring 20 to 30 cm in length and 10 to 15 cm in width, and are usually light yellow. The seeds produced by this cycad are roughly oval, approximately 2.5 to 3.5 cm long, and are enclosed in a characteristic yellow-orange fleshy covering known as a sarcotesta.
