Encephalartos mackenziei is a species of cycad in South Sudan. It is found in the Didinga Hills of Namorunyang State. [1]
This cycad grows up to 3.5 m tall with a stem diameter of 35 cm. It starts upright but then bends over, producing many secondary stems from basal shoots. The pinnate leaves form a crown at the top of the stem, reaching up to 1.5 m long. Each leaf has several pairs of oval-shaped, leathery, and hairy leaflets, 15–17 cm long, with 3-5 spines on the upper edge and a sharp tip. They attach to the stem at a 45° angle. This species is dioecious, with male plants bearing up to 10 long, slender cones, about 22 cm long and 9 cm wide, initially light green and turning yellow when ripe. Female plants have 1-2 large, egg-shaped cones, about 40 cm long and 16-18 cm wide, initially light green and changing to olive-brown when ripe. The seeds are roughly egg-shaped, 3.5 cm long, and have an orange-red sarcotesta. [3]
Encephalartos horridus, the Eastern Cape blue cycad, is a small, low-growing cycad up to 0.9 m (3.0 ft) high and 0.9 m (3.0 ft) wide. It is a native of Eastern Cape Province, South Africa, and found in arid shrublands, most commonly on ridges and slopes with shallow soils. The species is particularly known for its distinctly blue-gray leaves, although the degree of coloration can vary significantly. The species name horridus is Latin for 'bristly', after the plant's stiff, spiny leaflets.
Encephalartos brevifoliolatus, the escarpment cycad, is a cycad in the African genus Encephalartos. It is extinct in the wild. The escarpment cycad was found in short grasslands in the very open Protea savanna on the northern Drakensberg escarpment in South Africa's Limpopo Province. These plants are used to growing on large cliffs.
