It is a solitary palm growing about 16 m tall, with trunk diameter of up to 30 cm. It has a large and round leaf crown, with each leaf measuring about 5-6 m long. It is the main source of a botanical alternative to ivory known as Ecuadorean vegetable ivory or tagua. The seed is edible. Liquid endosperm is consumed as a drink. The leaves are cooked and the apical buds are eaten as a vegetable. The endocarp is very hard and used for making buttons, chess pieces, etc. The leaves are used as a thatch.

Edible Uses

Edible Parts: Apical bud  Fruit  Leaves  Seed
Edible Uses: Drink

The seed is eaten in various ways. When immature, the liquid endosperm is used as a refreshing drink[768 ]. As it becomes harder and more jelly-like, it is eaten as a food[768 ]. The orange, fleshy fruit is eaten as a delicacy[768 ]. Leaves - cooked[763 ]. The apical bud, often known as a 'palm heart', is eaten as a vegetable[763 ]. Eating this bud leads to the death of the tree because it is unable to make side shoots[K ].

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.
