BRIEF DESCRIPTION An evergreen tree (feather palm) reaching 7-20 m in height and 30-65 cm in trunk diameter. Roots black, very strong, extending up to 10 from the stem and going as deep as 3 m. USES All parts of the palm are used, and for a multitude of products. It contains large quantities of starshy sap in its trunk. The sap is converted to sugar when the palm flowers at 7-10 years of age and can be extracted from the male inflorescence stalks. The palm sugar is used in dishes, sweets, drinks and preserves. Young leaves, still white, are eaten in the same way as palm cabbage. Palm beetles are reared on fallen stems and consumed raw, fried or cooked. The leaf sheats, roots and the pith of the trunk are extracted for fibers used in the manufacture of brushes, roofs, fishing nets, cordage on ships, hats and to reinforce concrete. Sago starch can be extracted and used to prepare food. The fibers are very durable in sea water. It is also a source of honey and has medicinal properties. GROWING PERIOD Perennial. It begins to flower when it is 7-10 years old. The peduncles of the male inflorescences are tapped daily for about 60-90 days. Flowering continues for about 2 years, after which the palm dies.
