Encephalartos

Read about Encephalartos in the Standard Cyclopedia of Horticulture

Encephalartos (Greek combination, alluding to the bread-like interior of the trunk). Cycadaceae. Excellent cycads from tropical and southern Africa, grown chiefly for their evergreen foliage. The species are probably 20 or more, allied to Dioon and Macrozamia; with Stangeria, they constitute the peculiarly African representatives of the family. They are trees with stout cylindrical often fleshy trunks, and a terminal crown of stiff mostly spiny pinnate long Lvs. or fronds: fls. dioecious, in cones; staminate cone oblong, ovoid or cylindrical, the scales in many series, imbricate, thick and often rough, broadly or elongate-cuneate, with anthers on the under surface; pistillate cone ellipsoid or oblong, thick, the scales numerous in many series and imbricated, peltate, with the ovule beneath. For differences between this and related genera, see Vol. I, p. 120. From Dioon it is distinguished by its pinnate rather than pinnatifid Lvs., and from Cycas by straight rather than circinnate segms. in vernation, as well as by technical features of cones. These plants are specially suited for large conservatories, the fronds being not easily injured. They should succeed outdoors S. The trunks of some kinds grow only a few inches in many years. Most kinds prefer a sunny, tropical house, but E. brachyphyllus and perhaps others may be grown in a cool greenhouse if kept a little dry in winter. The cones are always interesting and often very decorative. Those of E. villosus are twice as large as a pineapple, orange-yellow, half revealing the scarlet frs. They are prop. by seeds; also by offsets or suckers. Some other cycads frequently produce seed in conservatories, but Encephalartos seldom does, and plants are, therefore, usually imported. Dry trunks, weighing frequently 50-75 lbs. have been received from S. Afr. They often remain dormant for a year or more, and do not make ornamental specimens for two or more years. They are slow-growing, except in very warm houses. They like a strong, loamy soil. While making new growth they need plenty of water. See Cycas. The woolliness of the stem and leaf-segments varies with the age of the plants and of the leaves. The pith and central portion of the cones of some species form an article of food among the Kafirs, hence the common name of Kafir bread. The most widely known species in cultivation are E. villosus, E. Altensteinii and E. pungens. Though very handsome cyads, they are by no means popular. They require much room for best results. In the following descriptions "rachis" refers to the midrib of the leaf on which the leaflets or segments are borne, and "petiole" means the part of the leaf below where the leaflets begin. E. Barteri, Carr. St. short, about 1 ft. high and to 9 in. diam.: Lvs. to 5 or 6 ft. long, and 10 in. broad, erect or suberect; petiole and rachis with a gray tomentum that falls off; lfts. about 80 pairs, linear-lanceolate, sharp at the apex, few-toothed: male cone to 9 in. long, pale: female cone about 8 in. long, oblong-ellipsoid, dark olive.

Geographical distribution of genus Encephalartos

Encephalartos is a genus of cycad native to Africa. Several species of Encephalartos are commonly referred to as bread palms or Kaffir bread since a bread-like starchy food can be prepared from the centre of the stem. All the species of Encephalartos are endangered. The genus name is derived from the Greek words en (within), kephali (head), and artos (bread), referring to the use of the pith to make food. Named by German botanist J.G.C. (Johann Georg Christian) Lehmann in 1834. All cycads except Cycas had been regarded as members of the genus Zamia until then, and some botanists continued to follow this line for many years after Lehmann had separated Encephalartos as a separate genus. His concept was originally much broader than ours today, including also the Australian plants we now know as Macrozamia and Lepidozamia.
