Summary

Raphia hookeri or commonly known as Ivory Coast Raffia Palm is a palm species native to Africa that can be about 10m in height. It is characterized by its compound pinnate leaves with each leaf reaching about 12m long, shiny dark green, and feather-like. It is a solitary palm and usually up to 30cm in stem diameter. The flowers and the top-shaped fruits are brown in color. A monocarpic plant, Ivory Coast Raffia Palm produces inflorescence only once then dies. The fruit is used in traditional medicine as laxative and liniment for pains. The plant has edible uses. Sap from the trunk is fermented into palm wine and fruits are boiled and eaten. The fruits, however, are poisonous if consumed raw. Other edible parts are the apical bud, starch obtained from the stem, and fruit oil. Further, among its many uses, Ivory Coast Raffia Palm is a source of a soft but strong fiber which is used to make mats, hats, baskets, hammocks, etc. Such fiber can also be made into paper. The leaves are used as thatching material while the leaf midribs and leaf stalks are used as poles and to construct the framework of houses. The wood is used for construction.

Habitats

Edible Uses

The sap from the trunk is fermented to make palm wine, which is a very popular drink in west Africa[297 , 299 ]. When fresh, the sap tastes like ginger beer. The alcohol content of the sap increases from less than 2% to about 5% during the first 8 days of tapping, remaining constant thereafter[299 ]. It is obtained from the inflorescence[301 ]. It is tapped from the stem when the tree nears the flowering stage[299 ]. The sap can be obtained either by cutting down the trunk and allowing the sap to drain out, or by boring a hole in the trunk near the apex[297 ]. Palm wine is obtained by piercing the base of the terminal bud, which leads eventually to the death of the palm[418 ]. The wine is distilled into a strong alcoholic liquor and can also be used as bakers' yeast[299 ]. Fruit - boiled and eaten[297 , 299 ]. Poisonous raw[299 ]. The apical bud is cooked and used like cabbage[299 , 301 ]. Harvesting this bud will eventually cause the death of the trunk because it is unable to make side branches[K ]. An edible starch is obtained from the stem[301 ]. An oil is obtained from the fruit[297 ].

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.



The oily mesocarp of the fruit is used in traditional medicine for its laxative and stomachic properties and as a liniment for pains[299 ].

Other Uses

Agroforestry Uses: In Nigeria, the plant sometimes serves as support for yams[299 ]. In Benin, tomatoes, cassava, sugar cane, red pepper and other crops are sometimes grown on earth ridges in Raphia hookeri swamps[299 ]. Other Uses Raffia, a soft but strong fibre, is obtained by pulling off ribbon-like strips from the upper surface of the leaflets of young unfolding leaves. It is used to make mats, hats, baskets, bags, ropes, hammocks, ceremonial costumes, etc[297 , 299 ]. It may be woven into cloth[299 ]. In Europe it is used as tying material for horticulture and handicrafts[299 ]. Raffia fibre has been considered as a potential source of pulp for paper production[299 ]. The tough fibre (known as piassava) obtained from the petioles and leaf sheaths, is used for making brooms[46 , 297 ]. It is used for the roller brushes employed in sweeping streets; for making mats, bags, hammocks, ropes, etc[418 ]. A tough, weather-resistant, coarse rope can also be made from this fibre[297 , 299 ]. Piassava fibre is also used to make exceptionally strong paper[299 ]. A very fine-textured charcoal, much favoured for the manufacture of home-made gunpowder, can be made from the fibre[299 ]. Piassava fibre is water resistant, hard-wearing, and has the right balance between stiffness and elasticity to give a firm stroke to a broom and sufficient spring action to make the broom self-cleaning. Mature leaves yield higher quality piassava fibre than younger leaves[299 ]. The large midribs of the leaves, and the leaf stalks, are widely used by native people to construct the framework of houses, as poles for various uses and for making into furniture, ladders etc[46 , 297 , 299 ]. They can be split into strips for maing screens, weaving into mats, baskets etc[297 , 299 ]. The leaves, split lengthwise, are used for thatching, though they last only 1 year[299 ]. They are also used to make mats, baskets and other articles of wickerwork, and are used for hut-walls and fences[299 ]. Wood - used for construction[297 ]. The stem can be used in house-building, both for the framework and roof-poles and also for furniture frames; the outer splints are used for heavy mat screens, hut partitions and ceilings[418 ]. The wood can be used after the sap has been allowed to drain[297 ].

Cultivation details

Industrial Crop: Fiber;  Management: Standard;  Regional Crop;  Staple Crop: Oil;  Staple Crop: Sugar.

A plant of the wet, lowland tropics, where it is found at elevations up to 200 metres. It grows best in areas where annual daytime temperatures are within the range 24 - 30?c, but can tolerate 14 - 36?c[418 ]. It prefers a mean annual rainfall in the range 3,000 - 4,000mm, but tolerates 2,000 - 5,000mm[418 ]. Requires a hot, sunny position in a moist soil[314 ]. Prefers a pH in the range 5 - 6, tolerating 4.5 - 6.5[418 ]. Dislikes saline soils[299 ]. Plants can tolerate being in flooded ground[314 ]. A monocarpic plant - growing for several years without flowering, then producing a massive inflorescence and dying after setting seed[200 ]. Inflorescences are produced more or less simultaneously in the axils of the most distal leaves. Tapping for wine may damage the developing inflorescence, making flowering impossible and accelerating death[299 ]. The time from planting to flowering in Raphia hookeri is 3 - 7 years[299 ]. Managed stands are mostly left to rejuvenate naturally by seed. In Nigeria, selected trees are left untapped for this purpose[299 ].

Propagation

Seed - pre-soak for 24 hours in warm water and sow in containers. The seed requires several months to germinate[297 ]. The germination period may range from 1 - 24 months, and the germination rate from 30 - 60%. Young plants are easily transplanted[299 ]. It has been claimed that seeds should be sown ventral side upwards, because the embryo is located on this side, but research has shown that seed orientation does not influence germination or seedling growth[299 ].
