Part 10

This small species has the stem from fifteen to twenty feet high, and varying from the thickness of a finger to that of the wrist, which it never exceeds. The stem is smooth and cylindrical, but distinctly ringed. The roots appear only a few inches above the ground. The leaves are pinnate, the leaflets elongate, triangular and cut at the ends. The column is short and cylindrical, and both it and the petioles are covered with short hairs or down. The spadices have long stalks and grow from beneath or from among the leaves; they are rather large and are simply branched. The spathes form sheaths at the bases of the spadices, and are persistent. The fruit is oval, of an orange-red colour, and about the size of the “hip” or wild rose fruit.

These trees grow on the Upper Amazon and Rio Negro in the dry virgin forest, where they occur in small scattered groves.

This species is of great importance to the Indian of the Rio Negro. With its stem he constructs his “gravatána” or blowing tube, which, with the little arrows before described as made from the spines of the Patawá, forms a most valuable weapon, enabling him to bring down monkeys, parrots and curassow birds from their favourite stations on the summits of the loftiest trees of the forest.

When he wishes to make a “gravatána” he searches in the forest till he finds two straight and tall stems of the “Pashiúba miri” of such proportionate thicknesses that one could be contained within the other. When he returns home he takes a long slender rod which he has prepared on purpose, generally made of the hard and elastic wood of the “Pashiúba barriguda,” and with it pushes out the pith from both the stems, and then with a little bunch of the roots of a tree fern, cleans and polishes the inside till the bore becomes as hard and as smooth as polished ebony. He then carefully inserts the slenderer tube within the larger, placing it so that any curve in the one may counteract that in the other. Should it still be not quite correct, he binds it carefully to a post in his house till it is perfectly straight and dry. He then fits a mouth-piece of wood to the smaller end of the tube, so that the arrow may go out freely at the other; and when he wishes to finish his work neatly, winds spirally round it from end to end, the shining bark of a creeper. Near the lower extremity he forms a sight with the large curved cutting tooth of the Paca (Cœlogenus paca), which he fixes on with pitch, and the gravatána is then fit for use.

These tubes are never less than eight and are often ten or twelve feet long, and on looking through a good one, not the slightest irregularity can be detected from one end to the other. The bore is generally not large enough to admit the tip of the little finger, so that the breath more readily fills the whole tube and propels the arrow with great velocity. The vertical direction is that in which the surest aim can be taken, and for which the gravatána is best adapted. When birds are feeding at the top of a lofty tree where the result of a gun-shot would be doubtful, a skilful Indian will take his station beneath it, and with a puff from his powerful lungs, will send up his little poisoned arrows with unerring aim. The wounded birds sometimes turn giddy and drop in a few seconds, or fly away to a neighbouring tree and in a minute fall heavily to the ground, or try to pluck out the arrows with their beaks, which, however, invariably break in the wound. The hunter carefully marks the direction in which each one falls, and when his quiver is emptied of arrows or the tree of birds, walks round and gathers up the game. His weapon makes no noise, and he therefore often does more execution than the best European sportsman armed with his double-barrel Manton.

Genus RAPHIA, Commerson.

Male and female flowers intermixed on the same spadix. No common spathe, but many small incomplete sheaths. Male flowers with from six to twelve stamens and no rudiments of a pistil. Female flowers with three sessile stigmas and barren stamens.

The stems are short, thick and ringed. The leaves are very large, regular and pinnate; the leaflets are linear and have spinulose midribs and edges. The bases of the petioles are sheathing, and persistent some way down the stem, and the margins are fibrous. The spadices grow from among the leaves, and are very large and much branched; and the fruit is oblong and covered with large imbricated scales.

There are three species of the genus known; one is a native of the west coast of Africa, another of Madagascar, while a third is found on the banks of the Lower Amazon.

Jupatí, Lingoa Geral.

This is one of the most striking of the many noble Palms which grow on the rich alluvium of the Amazon. Its comparatively short stem enables us fully to appreciate the enormous size of its leaves, which are at the same time equally remarkable for their elegant form. They rise nearly vertically from the stem and bend out on every side in graceful curves, forming a magnificent plume seventy feet in height and forty in diameter. I have cut down and measured leaves forty-eight and fifty feet long, but could never get at the largest. The leaflets spread out four feet on each side of the midrib. They are rather irregularly scattered and not very closely set; they droop at the tips and have weak spinules along the margins.

The stem does not generally exceed six or eight feet in height and is about a foot in diameter, clothed for some distance down with the persistent sheathing bases of the leaf-stalks and the numerous spinous processes which proceed from them. These spines are something like those of the “Patawá,” but not so thick and strong.

The spadices are very large, compoundly branched and drooping; they grow from among the leaves and have numerous bract-like sheaths in the place of spathes.

The flowers are of a greenish olive colour and densely crowded, and the fruit is large, oblong, and reticulated with large scales.

The petiole or leaf-stalk of this tree is most extensively useful. It is often twelve or fifteen feet long below the first leaflets, and four or five inches in diameter, perfectly straight and cylindrical. When dried, it almost equals the quill of a bird for strength and lightness, owing to its thin hard outer covering and soft internal pith. But it is too valuable to the Indian for him to use it entire. He splits off the smooth glossy rind in perfectly straight strips and makes baskets and window blinds. The remaining part is of a consistence between pith and wood, and is split up into laths about half an inch thick and serves for a variety of purposes. Window shutters, boxes, bird-cages, partitions and even entire houses are constructed of it. In the little village of Nazaré near Pará, many houses of this kind may be seen in which all the walls are of this material, supported by a few posts at the angles and fastened together with pegs and slender creepers (sipós).

The hand may be easily pushed through one of these walls, but as the inhabitants do not trouble themselves with the possession of any article worth stealing, they sleep as composedly as if stone walls and iron bolts shut them in with all the security of a more advanced civilization.

The same material is also used for stoppers for bottles, and we found it answer admirably for lining our insect boxes, holding the pins securely and being more uniform in its texture than cork.

This is the only American species of the genus, and it inhabits exclusively the tide-flooded lands of the Lower Amazon and Pará rivers, being quite unknown in the interior. When descending from the Rio Negro to Pará in the summer of 1852, I observed some of our Indians who had made the voyage before, pointing out this tree to their less travelled companions as one of the curiosities of the lower country not to be found in the “Sertaõ.”

It is probable that the leaf, though not entire, is the largest in the whole vegetable kingdom, some of them covering a surface of more than 200 square feet. In a few years we may be able to see them in the magnificent Palm House at Kew, where young plants are now growing.

Plate II. fig. 1, a fruit of Raphia tædigera of the natural size.

Genus MAURITIA, Linnæus.

Male flowers on one tree, female or hermaphrodite flowers on another. The spathes are imperfect, bract-ike, tubular sheaths. The male flowers have six stamens. The female flowers have a three-lobed stigma and six imperfect stamens.

The stems are either tall, columnar and smooth, or more slender and armed with strong conical spines. The leaves are all fan-shaped or radiating from a centre. The spadix is very large and pinnately branched, and grows from among the leaves. The fruits are of moderate size, oval or globular, and covered with rather small imbricated scales pointing downwards.
