Taxonomic notes


"The stout trunk, the top covered with brown wool, and the open and often flattish crown, help to identify this species ... The straight or curved leaves, yellowish-green when mature, have fairly narrow leaflets, the middle ones up to about 1/4 inch or just over, (7 mm) in width. A diagnostic feature, according to Dr Dyer, is the length of the middle leaflets, about 4 to 6 1/2 inches (roughly 10-17 cm) long, and about 7 mm broad, 7-9 nerved on the undersurface. The cones are woolly, grey or brown, and 3 or more - on some male plants up to 10 - are borne together, and these help to distinguish the species from E. cycadifolius with which it is often confused. The latter, however, is a shorter species with a stem rarely more than 2 feet (0.6 m) tall, cones borne singly, and a very limited distribution in the Bedford and Cradock mountains. The seeds of Encephalartos friderici-guilielmi are yellow, sometimes with an orange tinge" (Palmer and Pitman 1972).

Distribution and Ecology
