Raffia palmsare members of the genusRaphia.TheMalagasynamerafiais derived fromfia"to squeezejuice".[2]Thegenuscontains about twenty species ofpalmsnative to tropical regions of Africa, and especiallyMadagascar,with one species (R. taedigera) also occurring inCentraland South America.[1]R. taedigerais the source of raffia fibers, which are theveinsof the leaves, and this species produces a fruit called "brazilia pods", "uxi nuts" or "uxi pods".[3]

They grow up to 16 metres (52 ft) tall and are remarkable for theircompound pinnateleaves,the longest in the plant kingdom; leaves ofR. regalisup to 25 metres (82 ft) long[4]and 3 metres (9.8 ft) wide are known. The plants aremonocarpic,meaning that they flower once and then die after the seeds are mature. Some species have individual stems which die after fruiting, but have a root system which remains alive and sends up new stems which fruit.

Cultivation and uses

[edit]

Fiber

[edit]
Removing the membrane
Rolling the fibres together before drying
Weaving raffia.

Raffia fiber is produced from theepidermalmembraneon the underside of the leaf fronds. The membrane is taken off to create a long thin fiber, which can be rolled together for added strength before they are finally dried. Fibres can be made intotwine,rope,garden ties, and used in tree grafting.[2][5]Fibres are important in the area of textiles, as they can be dyed and woven into products such as decorativemats,baskets,placemats,hats, and shoes.

Raffia wine

[edit]

The sap of the palm can befermentedinto raffia wine.[2]It is traditionally collected by cutting a box in the top of the palm and suspending a large gourd below to collect the milky white liquid. Unlike withoil palms,this process kills the tree. Sap from both the raffia and oil palms can be allowed to ferment over a few days. When first collected from the tree, it is sweet and appears slightly carbonated. As it ages more sugar is converted. Raffia wine tends to be sweeter at any age when compared to oilpalm wine.Both kinds of palm wine can also be distilled into strong liquors, such asOgogoro.Traditionally in some cultures where raffia or oil palm are locally available, guests and spirits are offered these drinks from the palm trees.[citation needed]

Other uses

[edit]

In local construction, raffia fibres are used for ropes, with branches and leaves providing sticks and supporting beams, and various roof coverings.[2]The people of Ogba kingdom in Rivers State and other southern Nigerians use raffia palm fronds as fishing poles. The frond is usually cut from a young palm tree. The leaves are removed and the stake is dried, which becomes very light, and the hook is attached to a line, which is tied to the stake, making it a fishing pole.[citation needed]

The raffia palm is important in societies such as that of the Province ofBoholin the Philippines,KubaofDemocratic Republic of the Congo,NsoofCameroon,theIgboandIbibio/Annang/BahumonoofSoutheastern Nigeria,theTivofNorthcentral NigeriaandSouthwestern Cameroons,the Urhobo andIjaw peopleof the Niger deltaNigeriaand theYoruba peopleof southwestern Nigeria, among several other West Africanethnicnations.[citation needed]

Synthetic raffia

[edit]

A strand of raffia has a maximum length of about 1.5 m and an irregular width. When found onspoolsorhanksof greater lengths, it is likely synthetic raffia, produced frompolypropylene.First produced byCovemain collaboration withSulzer,a manufacturer of flat weaving looms for natural fibers, who adapted their looms to process synthetic raffia. These fabrics are used to make carpet backing, protective sheets, and bags for rice, potatoes, and citrus fruit. Covema also developed a method to cover raffia fabric with a thin film ofpolyethylenein order to make it waterproof.[6]
