Raffia palm

Raffia palms are members of the genus Raphia. The Malagasy name rafia is derived from fia "to squeeze juice". The genus contains about twenty species of palms native to tropical regions of Africa, and especially Madagascar, with one species (R. taedigera) also occurring in Central and South America. R. taedigera is the source of raffia fibers, which are the veins of the leaves, and this species produces a fruit called "brazilia pods", "uxi nuts" or "uxi pods".
They grow up to 16 metres (52 ft) tall and are remarkable for their compound pinnate leaves, the longest in the plant kingdom; leaves of R. regalis up to 25 metres (82 ft) long and 3 metres (9.8 ft) wide are known. The plants are monocarpic, 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. The Raphia palms are remarkable in being one of just two genera of flowering plants having the very rare phyllotaxy of 1/4 (the other is Laccosperma). Perhaps even more remarkable is the "King Raphia" (Raphia vinifera variety nigerica) which is the only known palm with pairs of opposite fronds.
Raffia fiber is produced from the epidermal membrane on 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 into twine, rope, garden ties, and used in tree grafting. Fibres are important in the area of textiles, as they can be dyed and woven into products such as decorative mats, baskets, placemats, hats, and shoes.
The sap of the palm can be fermented into raffia wine. 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 with oil 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 oil palm wine. Both kinds of palm wine can also be distilled into strong liquors, such as Ogogoro. Traditionally in some cultures where raffia or oil palm are locally available, guests and spirits are offered these drinks from the palm trees.
In local construction, raffia fibres are used for ropes, with branches and leaves providing sticks and supporting beams, and various roof coverings. 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.
The raffia palm is important in societies such as that of the Province of Bohol in the Philippines, Kuba of Democratic Republic of the Congo, Nso of Cameroon, the Igbo and Ibibio/Annang/Bahumono of Southeastern Nigeria, the Tiv of Northcentral Nigeria and Southwestern Cameroons, the Urhobo and Ijaw people of the Niger delta Nigeria and the Yoruba people of southwestern Nigeria, among several other West African ethnic nations.
