Characteristics

A tall branched palm. There are usually 4 crowns but occasionally 8 or 16. Each branch gives rise to a crown. Each crown has 8-20 fan shaped leaves. It grows 15-20 m tall. The stem is smooth but it has the scars of the old leaf bases. The leaves are broad (130-180 cm ) and with 20-40 long thin segments. The leaves are grey-green. The leaf stalk is 90-140 cm long and spiny with curved hooks along the edges. The male flower is 1.3 m long and the female flower is a similar length but is densely furry in the axils at the base of the fruit. The fruit is a dry fruit with a stone inside. They are about 7.5 x 5 cm and usually an irregular shape. The shiny outer layer encloses a middle layer which smells of gingerbread. This surrounds the hard stone which contains the seed kernel. The seeds are very hard and with a white kernel and a hollow centre. About 20-50 seeds weigh one kilogram. The mealy flesh of the fruit is edible.
