Selected Trees and Shrubs
Elaeis guineensis; Syn.: Elaeis melanococca, Common name: African Oil Palm, Oil Palm
Description: With the Coconut and Date palms, one of the three most important of the Palm family; stately, erect and handsome, up to 22 m tall (70 ft), usually less, with stout trunk, 30 cm diameter (12 in); leaves large, feathery and pinnately compound, 4.5-7.5 m long (15-24 ft), petioles (leaf bases) with saw-toothed thorns on margins; leaflets 100-150 pairs, 60-120 cm long (2-4 ft) and 3.5-5 cm broad (1.4-2.0 in); flowers set close to trunk in lower leaf axils, have separate male and female inflorescences, male in short clusters on inflorescence branches 10-15 cm long (4-6 in), female clusters are larger, bearing 200-300 flowers which eventually form the fruit bunches; fruits ovoid-oblong, about 3.5 cm long (1.4 in) and 2 cm wide (0.8 in), orange, red or black when ripe; palm oil produced from fleshy pericarp around seed; this oil naturally reddish due to high beta-carotene content; the more valuable palm kernel oil produced from white kernel within seed, similar to coconut oil; both oils high in saturated fatty acids, palm oil - 50%, and palm kernel oil - 80%; Gardens specimen, near Elmshall gate between cricket pitch and main road, is not known to fruit; fruit photos here are illustrative.
Plant Family: Belongs to the Arecaceae (Palmaceae) or Palm family, which includes Coconut (Cocus nucifera) and Date Palm(Phoenix dactylifera).
Natural Habitat: Thrives in hot humid climate on low-lying alluvial soil, ranging from savanna to rain forest, and on a wide range of tropical soils; propagation is by seed, germination in 4-8 months, but hastened by soaking in boiling water; bearing begins in 2-6 years, with full production between 12 and 30 years.
Origin and Distribution: Native to West Africa, especially S. Nigeria; introduced and cultivated throughout tropics, with plantations in Malaysia, Indonesia, Philippines, Honduras and Columbia, among others; and sometimes seen as an ornamental, as in south Florida.
Uses: Both palm oil and palm kernel oil widely used indigenously, and important commercially and in world trade; palm oil uses include manufacture of margarine, cooking oil, soaps and candles, as a lubricant, in biodiesel fuel, and as a surface protector in tin plate manufacture; palm kernel oil uses also include manufacture of margarine and cooking oil, and in ice cream and mayonnaise, baked goods and confectioneries, and in manufacture of soaps and detergents; the residual kernel cake used for stock feed; palm wine or toddy made from the fermented sweet sap of the male inflorescence; the soft heart of the leafy upper section of the stem is eaten as palm cabbage; leaves used to thatch huts; sometimes grown as ornamental, as in south Florida; medicinally, oil rich in carotene, and can be used in place of cod liver oil for correcting Vitamin A deficiency, and as a liniment; in indigenous folk medicine, reportedly used as an aphrodisiac and diuretic, and as a remedy for cancer, headache and rheumatism.
Indigenous Legends and Anecdotes: Palm Oil used in Africa for thousands of years, for cooking and in local medicines.
