Inaja or Maripa Palm (Attalea maripa) is a tall palm that grows up to 20 m tall with trunk diameter of up to 100 cm. It is native to South America and Trinidad and Tobago. The oil obtained from the kernel of the seeds has medicinal purposes. It is used through rubbing as relief from rheumatism. It can also be used in cooking. The large and brown or yellow fruit is edible and is used to make a drink. Endosperm of the seed is edible as well and often toasted. Further, the apical bud is eaten as vegetable. The pulp of the fruit yields oil for biodiesel production. Mature leaves are used for thatching while young leaves are used as weaving material. A. maripa can be used as a pioneer species due to its characteristics.
