Useful plants

Wood, fibre, shelter and craft

Raffia palms

Raphia spp.

Useful plants

Identify: Very large feather leaves, often the longest of any plant; stout trunks; scaly fruits.
Habitat: African swamp forest, river valleys and moist lowlands.
Season: Fiber and leaves year-round; sap/fruit seasonal.
Field use: Leaf fiber makes cordage, baskets and thatch; petioles make floats and light frames; sap and fruit have documented regional uses.
Caution: Harvest is skilled and can damage the palm. Swamps conceal deep water and animals.
Look-alikes: Oil palm has smaller leaves and orange fruit clusters.

Identify: Single trunk with pinnate leaves and dense clusters of orange-red oily fruits close to the crown.
Habitat: West and Central African rainforest, swamp margins and plantations.
Season: Fruit year-round to seasonal.
Field use: Processed fruit pulp and kernels yield calorie-dense oils; leaves and petioles provide thatch and basket material.
