Origin and geographic distribution
Pandanus abbiwii occurs in Ghana.
The leaves of Pandanus abbiwii are used for making mats, baskets and fish traps, while the fibrous root is used for brushes. The fruit has a pleasant flavour. An infusion of the bark is taken for the treatment of diarrhoea and dysentery.
Dioecious, small tree up to 12 m tall with aerial roots and a branched trunk. Leaves simple, without petiole but with broad clasping base, linear, up to 250 cm × 8 cm, tapering to the apex, margins and midvein with numerous sharp spines, with 94–100 longitudinal veins. Infructescence consisting of 3–5 syncarps; apical syncarp suboblong, c. 26 cm × 12.5 cm. Fruit a 4–9-angular drupe 4–4.5 cm × 1.5 cm × 1.5 cm, usually 2–3-locular, yellow when ripe, upper part of drupe free and dome-shaped.
Pandanus includes about 600 species and is found from West Africa eastward to Madagascar, the Indian Ocean islands, India and most of warmer South-East Asia and the Pacific islands. From Madagascar c. 80 Pandanus species have been reported, and from mainland Africa some 25 species.
Pandanus candelabrum P.Beauv. occurs in Nigeria, where the leaves have been used for making bags for holding salt. In traditional Nigerian medicine the leaves are used for the treatment of sore throat, and bark infusions are used to cure diarrhoea, dysentery and enteritis. Formerly, all Pandanus plants occurring from Senegal eastwards to Angola were considered to belong to Pandanus candelabrum, but more recently a range of species with restricted endemicity have been identified, among which Pandanus abbiwii. As recorded uses of Pandanus in West and Central Africa have usually been attributed to Pandanus candelabrum and not to the new species, assessment of the uses and properties of most new species is difficult.
In Sierra Leone material for weaving mats is obtained by scraping the leaf of Pandanus triangularis H.St.John ex Huynh between a knife and the fingers and drying the product in the sun. Fibre obtained after retting the leaf in water is made into rope, which is sometimes used for making long baskets in which fish are put when caught.
Pandanus abbiwii occurs along rivers and near beaches.
In view of the limited distribution of Pandanus abbiwii the risk of genetic erosion may be high.
Pandanus abbiwii is a useful local source of material for weaving. Little is known about this species, however. The taxonomy of Pandanus in West and Central Africa needs further elucidation.
