Astrocaryum chambira is a solitary-stemmed palm tree growing 3.5 - 30 metres tall. The unbranched stem is covered in black spines that are up to 20cm long; it can be 19 - 35cm in diameter and is crowned by a rosette of 9 - 16 erect leaves that can each be 5 metres or more long. The tree is commonly harvested, especially for its useful fibre, but also for its edible apical bud and medicinal uses. It is often planted because of it's useful properties.
Cold Hardiness Zone: 10b.
Comments and Curiosities
Ethnobotany: The crown shaft and young fronds provide excellent fiber that is used for string, rope, hammocks, bags, and many crafts. People even floss their teeth with the fiber. The fruit is popular, as well as the liquid endosperm. This is drunk to cleanse internal organs, especially the kidneys and liver, and to reduce fevers. Leaves - cooked The apical bud is eaten as a vegetable. Eating this bud leads to the death of the plant because it is unable to produce side-shoots. Fruit - raw. Both the mature and the immature fruits are eaten.
The fruits are used to treat erysipelas. The fruit pulp is said to be antihelminthic. The liquid endosperm is drunk to cleanse internal organs, especially the kidneys and liver, and to reduce fevers. Other Uses: The fibres obtained from the youngest, unexpanded leaves are commonly used to weave a variety of items, especially hammocks, nets, necklaces and bags. The fibre can be used as a floss to clean the teeth.
Its use among four different indigenous groups in Ecuador is described here. They extract fibers from the pinnae, mostly of the young leaves. Both men and women twist the fibers into strings in their homes after hunting and work in the fields. The main items produced are woven hammocks, bags, and nets. These products represent the main source of cash income for many indigenous people. The highest value for their products is obtained from sale directly to tourists. The commercial use of A. chambira can possibly be increased in extractivism along with better marketing. The variety of ways this palm is used also makes it a valuable species for agroforestry.
Agroforestry: Chambira will grow from discarded seeds, and is commonly planted. Seed germination is tricky. It should be spaced at least six meters apart, and needs full sun. The trunk is very spiny, causing work accidents. It is common to plant a climbing tree next to the palm in order to safely harvest fiber and fruit. It grows well in non-flooding environments, but can attract animal pests to the field. As a result, hunting is practiced in these agroforestry systems. Where chambira crafts are sold to tourists, it is increasingly cultivated.
This beautiful, large, solitary palm from the Amazon rainforest in northwestern South America resembles the famed Dictyocaryum lamarckianum in general aspect but is of course extremely spiny, like all Astrocaryum. In cultivation it makes an interesting, quick, and easy-to-grow palm mainly for tropical areas. The large seeds are edible and very tasty. (Rare Palm Seeds.com)
