About Encephalartos friderici-guilielmi
Encephalartos friderici-guilielmi is a species of cycad belonging to the Zamiaceae family, commonly known as the White-haired Cycad. This distinctive plant is native to the Eastern Cape and KwaZulu-Natal provinces of South Africa, where it typically inhabits mountainous terrain at elevations ranging from 700 to 1400 meters.
Description and Characteristics
The White-haired Cycad is characterized by its tree-like trunks, which can attain a height of up to 4 meters and a width of 35 to 60 centimeters. Its crown is openly structured and displays a woolly brown appearance. The leaves are a prominent feature, measuring between 1 and 1.5 meters in length and 18 to 20 centimeters in width, fanning out horizontally from the trunk. These leaves are notably stiff and can be straight or slightly curved. In their youth, the leaves exhibit a silvery hue, which matures into a yellowish color over time. The petiole, or leaf stalk, is bare, circular in cross-section, and measures 17 to 30 centimeters long.
The leaflets of Encephalartos friderici-guilielmi are arranged tightly along the leaf axis. The upper leaflets tend to overlap, while the middle ones are typically 10 to 17 centimeters long and 7 to 8 millimeters wide. A distinguishing characteristic is the presence of 7 to 9 prominent veins on the base of each leaflet. Unlike some other cycads, the leaf margin is not serrated; instead, the leaf tip terminates in a sharp thorn.
Reproductive structures are also notable. The female cones are barrel-shaped, measuring 25 to 30 centimeters in length and 15 to 20 centimeters in diameter, frequently adorned with a dense covering of yellow-gray to brown wool. These cones can appear singly or in clusters of up to six. The male cones are cylindrical, ranging from 20 to 40 centimeters in length and 6 to 10 centimeters in diameter, also covered in brown wool. They typically emerge in groups of three to twelve.
Seeds
The seeds of Encephalartos friderici-guilielmi are also distinctive. The sarcotesta, the fleshy outer layer of the seed, is pale yellow to pale yellow-orange. Beneath this lies the sclerotesta, the hard inner shell, which is medium brown and marked by clear longitudinal furrows. The seeds are substantial, measuring 24 to 33 millimeters in length and 16 to 20 millimeters in diameter.
