Synonyms: Borassus flabellifer L. var. aethiopum (Mart.) Warb.
Common names: Borassus palm (English)
Description: Large palm tree. Stems erect, up to 20 m, with a distinct swelling above the middle. Leaves crowded on top of the stem, fan-shaped, blue-green up to 4 m including the petiole. Petiole armed with recurved thorns. Flowers in large branched sprays, unisexual on separate trees, female flowers larger than male. Fruit large, 12-18 cm in diameter, subspherical, orange-brown.
Notes: This species can be mistaken for H. coriacea but is a much stouter tree with larger leaves and fruits and mature trees have the distinctive swelling in the trunk. Seriously threatened by increased exploitation to brew a strong alcoholic drink from the sap. Mature trees are cut and killed for this purpose.
Derivation of specific name: aethiopum: Ethiopia, the name of the sub-Saharan biological region before the country formerly known as Abyssinia claimed the name Ethiopia.
Flowering time:Aug - Oct
Worldwide distribution: Sudanian, Zambezian and Coastal phytochoria, extending to northern South Africa.
