About Encephalartos cycadifolius

Encephalartos cycadifolius is a species of cycad native to the Winterberg mountains, situated north of Bedford in the Eastern Cape province of South Africa. This species is found at considerable altitudes, typically between 1,200 and 1,800 meters above sea level.

Description and Botany

The plant is characterized by an underground trunk that can extend up to 1.5 meters in height and reach a diameter of 25-30 cm. It often exhibits secondary growth, with new stems emerging from basal shoots. The leaves of Encephalartos cycadifolius are pinnate, measuring between 60 and 90 cm in length, and arranged in a crown at the apex of the stem. Each leaf is borne on a thornless petiole that is 10-20 cm long. The leaves are composed of numerous lanceolate leaflets, approximately 9-12 cm long, which have entire margins and are a distinct olive-green color.

Reproduction

Encephalartos cycadifolius is a dioecious species, meaning that individual plants are either male or female. Male specimens produce one or two cylindrical-conical cones, which are 13–22 cm in length and 5–7 cm in breadth, covered in a grayish tomentum. Female plants bear one or two cylindrical-ovoid cones that are pedunculate, measuring 20–30 cm in length and 16–18 cm in diameter. These female cones are greenish-yellow and densely covered with tomentum. The seeds are roughly ovoid, about 20–30 mm long, and are enclosed in a sarcotesta that can be yellow-orange to amber in hue.
