Comments and Curiosities

Uses: The weaved pinnae of the leaves are used for thatch. Leaves are used to make temporary baskets. Fibres from the leaf base of juvenile plants are used to make brooms. The mesocarp, preferably mature, is edible. The endosperm is also edible when immature in a liquid or jelly-like state. The endosperm is eaten to cure diarrhea and stomach ache.
