The stem is generally short, but reaches twenty to thirty feet in height, and is much thicker than in either of the preceding species. The leaves are very large and regularly pinnate, with the pinnæ gradually smaller to the end, as in the two former species. The leaflets are rigid, broadest in the middle, and gradually tapering to a fine point, spreading out flat on each side of the midrib, but slightly drooping at the tips. The petioles are slender and smooth. The spadix is large, excessively branched and drooping, and there are often several on the same tree. The marginal processes of the petioles are interlaced as in the two former species, and are produced into long riband-like strips, which afterwards split into fine fibres, and hang down five or six feet, entirely concealing the stem, and giving the tree a most curious and unique appearance. The leaves form an excellent thatch, and are almost universally used in that portion of Venezuela situated on the upper Rio Negro, and the adjacent tributaries of the Orinoco. The fruit is said to resemble that of the Jará in colour, but it is globose and eatable, being used principally to form a thick drink by washing off the outer coating of pulp. The fibrous or hairy covering of the stem is an extensive article of commerce in the countries in which it grows. It seems to have been used by the Brazilians from a very early period to form cables for the canoes navigating the Amazon. It is well adapted for this purpose, as it is light (the cables made of it not sinking in water) and very durable. It twists readily and firmly into cordage from the fibres being rough-edged, and as it is very abundant, and is procured and manufactured by the Indians, piassaba ropes are much cheaper than any other kind of cordage. The price in the city of Barra in June 1852, was 400 reis or 1_s._ for 32 lbs. of the fibre, and 800 reis or 2_s._ for every inch in circumference of a cable sixty fathoms long, which is the standard length they are all made to.
