Pashiúba, Lingoa Geral.
This curious and beautiful tree is common in the forests about Pará and on the banks of the Amazon. It reaches fifty or sixty feet in height, with the stem moderately thick and very smooth, there being scarcely any rings or scars left by the fallen leaves.
The leaves are large and pinnate, with the leaflets triangular and very deeply notched, standing out at different angles with the midrib. The leaves curve over gracefully, and the character and aspect of the foliage is very different from that of most other palms. The column formed by the sheathing leaf-stalks is swollen at the base and of a deep green colour.
The spadices are three or four in number, growing rather upwards from the stem below the leaf-column. They are small and simply branched, and bear small oval red fruits about the size of a damson, the outer pulp of which is bitter and only eaten by some birds.
But what most strikes attention in this tree, and renders it so peculiar, is, that the roots are almost entirely above ground. They spring out from the stem, each one at a higher point than the last, and extend diagonally downwards till they approach the ground, when they often divide into many rootlets, each of which secures itself in the soil. As fresh ones spring out from the stem, those below become rotten and die off; and it is not an uncommon thing to see a lofty tree supported entirely by three or four roots, so that a person may walk erect beneath them, or stand with a tree seventy feet high growing immediately over his head.
In the forests where these trees grow, numbers of young plants of every age may be seen, all miniature copies of their parents, except that they seldom possess more than three legs, which gives them a strange and almost ludicrous appearance.
The figure on the opposite page (Plate XIII.) represents accurately the roots of a tree which had been partly blown down in the forest of the Upper Rio Negro. My friend Mr. Spruce informs me that it is a distinct species from that found at Pará, though closely allied to it, and scarcely differing in the character of the roots.
The wood of these trees is very hard on the outside, but soft and pithy within. It splits easily and very straight, and is much used for forming the floors of canoes, the ceilings of houses, shelves, seats, and various other purposes. Perfectly straight laths are more readily made from it than from any other wood, and they are so hard and durable as to serve for fish-weirs, corals for turtles, and for harpoons. The air-roots are covered with tubercular prickles, and are used by some Indians to grate their mandiocca.
This species grows in swamps or marshy ground in the virgin forest, not in the tide-flooded lands on the river banks.
Young plants may be seen in the great Palm House at Kew.
