Part 4

This is one of the most noble and majestic of the American Palms. It grows to a height of eighty or a hundred feet. The stem is straight and smooth, about five feet in circumference, often perfectly cylindrical, but sometimes swollen near the middle or towards the top, so that the bottom is the thinnest part.

The leaves spread out in every direction from the top of the stem. They are very large and fan-shaped, the leaflets spreading out rigidly on all sides and only drooping at the tips and at the midrib or elongation of the petiole. The leaves stand on long stalks which are very straight and thick, and much swollen at the base which clasps the stem. A full-grown fallen leaf of this tree is a grand sight. The expanded sheathing base is a foot in diameter; the petiole is a solid beam ten or twelve feet long, and the leaf itself is nine or ten in diameter. An entire leaf is a load for a man.

The spadices grow out from among the leaves; they are very large, pinnately branched and horizontal or drooping. The fruit is spherical, the size of a small apple and covered with rather small, smooth, brown, reticulated scales, beneath which is a thin coating of pulp. A spadix loaded with fruit is of immense weight, often more than two men could carry between them.

The leaves, fruit and stem of this tree are all useful to the natives of the interior. The leaf-stalks are applied to the same purposes as those of the species last described, the Jupatí. The epidermis of the leaves furnishes the material of which the string for hammocks, and cordage for a variety of purposes is made. The unopened leaves form a thick-pointed column rising from the very centre of the crown of foliage. This is cut down, and by a little shaking the tender leaflets fall apart. Each one is then skilfully stripped of its outer covering, a thin riband-like pellicle of a pale yellow colour which shrivels up almost into a thread. These are then tied in bundles and dried, and are afterwards twisted by rolling on the breast or thigh into string, or with the fingers into thicker cords. The article most commonly made from it is the “réde,” or netted hammock, which is the almost universal bed of the native tribes of the Amazon. These are formed by doubling the string over two rods or poles about six or seven feet apart, till there are forty or fifty parallel threads, which are then secured at intervals of about a foot by cross strings twisted and tied on to every longitudinal one. A strong cord is then passed through the loop formed by all the strings brought together at each end, by which the hammock is hung up a few feet from the ground, and in this open net the naked Indian sleeps beside his fire as comfortably as we do in our beds of down.

Other tribes twist the strings together in a complicated manner so that the hammock is more elastic, and the Brazilians have introduced a variety of improvements by using a kind of knitting needles producing a closer web, or by a large wooden frame with rollers, on which they weave in a rude manner with a woof and weft as in a regular loom. They also dye the string of many brilliant colours which they work in symmetrical patterns, making the rédes or “maqueiras” as they are there called, among the gayest articles of furniture to be seen in a Brazilian house on the Amazon.

From the fruits a favourite Indian beverage is produced. They are soaked in water till they begin to ferment, and the scales and pulpy matter soften and can be easily rubbed off in water. When strained through a sieve it is ready for use, and has a slight acid taste and a peculiar flavour of the fruit at first rather disagreeable to European palates.

In the tidal districts about Pará, the massive trunks of these trees are often used to form a raised pathway across the expanse of soft mud generally left at low water between “terra firma” and the water’s edge. A smooth and slippery cylinder is certainly not the best thing that could be devised for this purpose, but as it is the most easily procured and the least expensive it is proportionately common, and on paying a visit to many a Brazilian country house, should you arrive at low water, you will have no other means of getting ashore.

The Miriti is a social palm, covering large tracts of tide-flooded lands on the Lower Amazon. In these places there is no underwood to break the view among interminable ranges of huge columnar stems rising undisturbed by branch or leaf to the height of eighty or a hundred feet,—a vast natural temple which does not yield in grandeur and sublimity to those of Palmyra or Athens.

Of the age of these noble trees we have no knowledge, but it is remarkable how uniform they appear in size, there often being not a single young tree over a considerable extent of ground, particularly in places now flooded daily by the tide. One would therefore imagine that the present trees sprung up when the ground was more elevated than at present, and that it has since gradually sunk (or the waters risen) till the conditions have become unfavourable for the growth of young plants, though not hurtful to those which had already attained a certain age. Whether such is the true explanation of the phænomenon can only be decided by continued observation on the spot.

Besides this species which is mentioned by Martius as occurring at Pará, my friend Mr. Spruce ascertained that another closely allied palm, the _Mauritia vinifera_, also occurs there. On the Upper Amazon and Rio Negro a palm is found supposed to be the _M. flexuosa_, but it is not so lofty a tree, which may perhaps be accounted for by its growing on annually instead of diurnally flooded lands. It is believed to be the same species which Humboldt observed on the Serra Duida. The Itá palm growing on the delta of the Orinoco is also thought to be the same species. On the river Uaupes, a branch of the Upper Rio Negro, I observed an allied species called by the natives “Caraná assu.” The stem was smooth and much more slender and waving, and the leaves much smaller.

Plants of the _Mauritia flexuosa_ are growing in the Palm House at Kew.

On Plate XVII. a single leaf is represented, showing the flabellate form produced by abbreviation of the midrib.

Plate II. fig. 2. is a fruit of the natural size.

PLATE XVIII. MAURITIA CARANA, n. sp.

Caraná, _Lingoa Geral_.

This is a large smooth-stemmed species allied to _M. flexuosa_, but quite distinct and hitherto undescribed. The stem is about a foot in diameter and from twenty to forty feet high, smooth and obscurely ringed. The leaves are very similar to those of the Mirití, but the leaflets are not so deeply divided, being united together at the base for one-third of their entire length, and much more drooping at the tips. The petioles are very large, straight and cylindrical; their dilated bases are persistent for a considerable distance down the stem, and their margins give out a quantity of fibres which clothe it as in the _Leopoldinia piassaba_, though rather less densely.

The spadices grow from among the leaves and are somewhat more erect and much smaller than in the Mirití, and the fruits are less abundant, smaller and slightly ovate.

The leaf-stalks of this species are used for the same purposes as those of the Mirití and Jupatí already described, as those palms are generally absent where this is abundant. The part most generally used, however, is the leaf, which for thatching is preferred to that of any other species, on account of its having so large a portion of the base entire and being of a very durable texture. A roof well-thatched with Caraná will last eight or ten years without renewing, and the leaves are so constantly cut for this purpose that it is hardly possible to find an entire and handsome tree. Though so closely resembling the Mirití, the epidermis is never used for cordage, and on my asking an Indian the reason, he quite laughed at the idea, saying that it was quite impossible because the Caraná “did not produce any thread.”

This tree grows in the district of the Rio Negro and Upper Orinoco, but is not found on the Amazon. It prefers the dry Catinga forests, or the sandy margins of streams out of reach of the highest floods. At Javita I observed it growing within a few yards of the Mirití, but still preserving all its distinctive characters.

It is called by the natives Caraná, the smaller prickly stemmed species being known by the name of Caranaí.

PLATE XIX. MAURITIA ACULEATA, _Humboldt_.

Caranaí, _Lingoa Geral_ (_Rio Negro_). Caraná? (_Pará_).

This species has a tall, erect and slender stem reaching about forty or fifty feet in height and armed with numerous, long, conical, woody spines arranged in rings. The leaves are rather small with the leaflets rigid and very slightly drooping at the tips, and united at the base for about one-eighth of their length. The petioles are long and slender and are deciduous, the entire leaf falling away from the stem. The midrib and edges of the leaflets are armed with weak spinules. The spadices are small and grow somewhat erect so as to be partly concealed among the leaves, and the fruit is oval and rather small.

This species grows on the Upper Rio Negro and Atabapo, in marshes, with a rocky subsoil, and in the moist parts of the Catinga forest. The Caraná, common in the swamps (not in the tide-flooded lands) about Pará, is very closely allied or may be the same species.

PLATE XX. MAURITIA GRACILIS, n. sp.

Caranaí, _Lingoa Geral_.

This very elegant species is rather smaller than the last. The stem is from twenty to thirty feet high, slender, waving, and ringed with conical spines rather smaller than in _M. aculeata_.

The leaves are from five to eight in number with much-drooping leaflets. The petioles are slender, short, and greatly dilated at the base. The spadices are three or four in number, growing from among the leaves, of very large size in proportion to the tree, much branched and drooping. They bear great quantities of fruit, which is of an oval shape and nearly as large as that of the _Mauritia carana_.

This beautiful little palm is first met with about Barcellos on the Rio Negro, more than 300 miles up the river, and is thence common as far as the black-water tributaries of the Orinoco. It always grows close to the water’s edge in clumps of thirty or forty individuals, and its drooping leaves of a pale hoary green colour, never so much crowded as to lose their distinct outline, with the bending clusters of rich brown fruit, render it one of the greatest ornaments of its native river. The fruit is eaten, after being softened by soaking some time in water.

It seems closely allied to _M. armata_ of Martius, which is found much farther south, on the banks of the S. Francisco River, but is probably quite a distinct species.

PLATE XXI. MAURITIA PUMILA, n. sp.

Caranaí, _Lingoa Geral_.

This curious little palm is only eight or ten feet high, and has the stem slender, ringed, and armed with strong conical spines. The leaves are rather small and few in number, and the leaflets are much shorter, broader and more rigid than in any other palm of this genus. The petioles are long and rather thick, much sheathing at the bases which are persistent, clothing the stem some distance down after the leaves have dropped away from them, a character not found in any other prickly stemmed species. The spadix is very long, branched and drooping. The fruit was not seen.

I only met with this palm on the Upper Rio Negro in two localities on the sandy margins of rivers and lakes just above the limits of the winter floods.

Genus LEPIDOCARYUM, _Martius_.

Male flowers on one tree, female or hermaphrodite flowers on another. Spathes, imperfect, bract-like, tubular sheaths. The male flowers have six stamens. The female flowers have three sessile stigmas and six imperfect stamens.

The stems are very slender, unarmed with spines or tubercles and deeply ringed. The leaves are fan-shaped, and have slender petioles and long swollen sheaths. The spadices are elongate and pinnately branched, growing from among the leaves. The fruits are oblong and covered with imbricated scales.

These delicate and very rare little Palms scarcely differ botanically from the last genus. Two species only are known, inhabiting the dense virgin forests of the Upper Amazon and Rio Negro, where they appear to be very locally distributed.

PLATE XXII. LEPIDOCARYUM TENUE, _Martius_.

Caranaí do Mato, _of the Rio Negro_.

This, the smallest of the fan-leaved Palms, has a smooth, ringed, waving stem as thick as one’s finger and six or eight feet high. Its dark green glossy leaves, with narrow drooping leaflets, grow on long and slender stalks which have their sheathing bases much swollen and lengthened.

The spadices are small and slender, and the fruits, which are not abundant, are scaled in the same manner as those of the Mauritias, and are about the size of a large hazel-nut.

This rare and elegant species grows in the gloomiest depths of the virgin forest of the Upper Rio Negro, generally at some distance inland from the rivers, and shaded by the loftiest forest trees.

Plate II. fig. 4. represents a fruit of this species of the natural size.

Genus GEONOMA, _Willdenow_.

Male and female flowers on distinct trees, or rarely on distinct spadices of the same tree. Spathe small, incomplete. Male flowers with six stamens and a rudimentary pistil. Female flowers with three stigmas and a six-toothed ring of abortive stamens.

These are small palms with slender, smooth, ringed, reed-like stems. The leaves are large, regularly or irregularly pinnate, with the leaflets broad, and the bases of the petioles sheathing. The spadices are slender and more or less branched, and the spathes are double but small and membranous. The fruits are small, round or ovate, and are not eatable.

There are thirty-three species of this genus known, all of small size, and inhabiting various parts of South America and Mexico, from the level of the sea to 2000 feet above it. Many species may be seen flourishing in the Palm House at Kew.

PLATE XXIII. GEONOMA MULTIFLORA, _Martius_.

Ubimrána, _Lingoa Geral_.

This handsome species is from eight to fifteen feet high, and has the stem regularly ringed or jointed, giving it a reed-like appearance. The leaves are very large, regularly pinnate and gracefully drooping on every side. The leaflets are very regularly placed on the midrib, and the terminal pair are much larger and broader. The petioles are slender and smooth, and the sheathing bases have an expanded fibrous margin.

The spadices grow from among the lower leaves, and are short, erect and simply branched. The spathes are very small and concealed among the petioles. The fruit is small, ovate, and when ripe of a red colour.

This appears to be the _Geonoma multiflora_ of Martius, but the species are so closely allied that without a comparison of specimens it is very difficult absolutely to identify them.

I have found it only in the Catinga forests of the Upper Rio Negro, where it occurs very sparingly.

A fruit is represented on the Plate of the natural size.

PLATE XXIV. GEONOMA PANICULIGERA, _Martius_.

Ubim de Cotiwiya, _Lingoa Geral_.

This is a species from six to nine feet high and very similar in appearance to the last. The leaves, however, have only three or four pairs of leaflets of irregular width, the terminal pair being always very large and broad, and the others not being always placed opposite each other on the midrib.

The spadix is large, much branched and somewhat drooping, and has a small, soft and inconspicuous basal spathe. The fruit is small and round.

This species grows in the same localities and in the same soil as the last, but is much more abundant. It appears to agree well with the _G. paniculigera_ of Martius.

There is a very closely allied species abundant in certain parts of the flooded lands or “gapó” of the Rio Negro, which is much used for thatching. The leaves being cut, the leaf-stalks are doubled and hitched on side by side to a strip of “pashiúba,” and secured with “sipós” (which are the air-roots of _Arums_ and other plants). They are said to make one of the most durable kinds of roof, and are much used for covering the semicircular “toldas” of canoes. They are also considered the best material for lining baskets of salt, and persons often go several days’ journey to procure them for both these purposes.

I had no opportunity of closely examining the species which produces these leaves, and which is called “Ubim,” in contradistinction to the other allied species which are termed “Ubimrana” (false ubim), “Ubim de cotiwiya” (Agouti’s ubim) and other such names, and all of which, though sometimes used as substitutes, are said to be much less durable.

PLATE XXV. GEONOMA RECTIFOLIA, n. sp.

Ubimrána, _Lingoa Geral_.

This little species is nearly allied to the last. It reaches six or eight feet in height and has the stem distinctly jointed and the leaves persistent some way down it. The petioles grow very upright, and there are three or four pair of long, narrow and rather rigid leaflets, the terminal being the largest.

The spadices are numerous from the axils of the lower leaves, and are small and simply branched; and the fruit is very small, round and black.

This palm may be distinguished from _G. paniculigera_, to which it is most closely allied, by its very long narrow leaflets and much more erect habit; and by its smaller and less-branched spadices growing lower down on the stem, often below the leaves.

I found it in a few localities only on the Upper Rio Negro, growing in the sandy Catinga forest near the margin of the river.

A fruit is represented on the Plate of the natural size.

Genus MANICARIA, _Gærtner_.

Male and female flowers in the same spadix. Spathe fusiform, fibrous, complete, breaking open irregularly. Male flowers with twenty-four to thirty stamens. Female flowers (situated below the male) with three sessile stigmas and twelve rudimentary stamens.

Stem short, thick and irregularly ringed. Leaves very large, entire and rigid, the sheathing bases persistent. Spadices simply branched, growing from among the leaves, nearly erect. Fruit large, hard, somewhat triangular or three-lobed and three-seeded, externally very rugose.

Only one species of this genus is known, which inhabits the Lower Amazon at the level of the sea.

PLATE XXVI. MANICARIA SACCIFERA, _Gærtner_.

Bussú, _Lingoa Geral_.

This unique and handsome palm has the stem from ten to fifteen feet high, curved or crooked and deeply ringed. The leaves are very large, entire, rigid and furrowed, and have a serrated margin; they are often thirty feet long and four or five wide, and split irregularly with age. The petioles are slender with a broadly expanded fibrous-edged sheath at the base. These sheaths are persistent and often cover the stem down to the ground.

The spadices are numerous, growing from among the leaves, and are simply branched and drooping. The fruit is of an olive colour, somewhat three-lobed and with a rugose or papillate exterior covering. The spathe is fusiform and entire, of a fibrous cloth-like texture and of a brown colour. As the spadix expands it breaks open irregularly, but in some cases a dead unopened flower bunch is found enclosed in an entire half-rotten spathe, as if the vital powers of the plant had not been sufficient to tear asunder the tough fibrous sheath.

The “bussú” produces the largest entire leaves of any known palm, and for this reason, as well as on account of their firm and rigid texture, they form the very best and most durable thatch. The leaves are split down the midrib and the halves laid obliquely on the rafters, so that the furrows formed by the veins lie in a nearly vertical direction and serve as so many little gutters to carry off the water more rapidly. A well-made thatch of “bussú” will last ten or twelve years, and an Indian will often take a week’s voyage in order to get a canoe-load of the leaves to cover his house.

The spathe too is much valued by the Indian, furnishing him with an excellent and durable cloth. Taken off entire it forms bags in which he keeps the red paint for his toilet or the silk cotton for his arrows, or he even stretches out the larger ones to make himself a cap,—cunningly woven by nature without seam or joining. When cut open longitudinally and pressed flat, it is used to preserve his delicate feather ornaments and gala dresses, which are kept in a chest of plaited palm leaves between layers of the smooth “bussú” cloth.

This species inhabits the tidal swamps of the Lower Amazon. A palm called “bussú” is also found on the Rio Negro and Upper Amazon, but it is of a smaller size and is probably a distinct species.

A spathe is represented on the Plate and a dead stem from which the leaves have entirely fallen.

Plate II. fig. 3, a fruit of _Manicaria saccifera_ of the natural size.

Genus DESMONCUS, _Martius_.

Male flowers on the upper parts of the branches of the spadix, females on the lower. Spathe fusiform, woody, at length deciduous. Male flowers with six stamens and linear acute anthers. Female flowers with a short style and three stigmas and six small scaly rudiments of stamens.

Stems slender, flexible, climbing over shrubs or trees. Leaves alternate, pinnate, much sheathing, with long hooked spines in the place of the three or four terminal pair of leaflets. The spadices are axillary and simply branched, the spathes double, fusiform or ventricose, and the fruits are small, round, and generally red. The stems and leaves are more or less prickly.

Fourteen species of these curious Palms are found in various parts of South America, principally in the low lands, as they are not known at a greater height than 2000 feet above the level of the sea. They differ remarkably from all other American palms in their long climbing stems, in which they resemble the Calami or Canes so abundant in the East Indies.

PLATE XXVII. DESMONCUS MACROACANTHUS, _Martius_.

Jacitára, _Lingoa Geral_.

The stem of this palm is very slender, weak and flexible, often sixty or seventy feet long, and climbing over bushes and trees or trailing along the ground. It is armed with scattered tubercular prickles. The leaves grow alternately along the stem; they are pinnate, with from three to five pairs of leaflets, beyond which the midrib is produced and armed with several pairs of strong spines directed backwards, and with numerous smaller prickles. The leaflets are ovate, with the edges waved or curled. The bases of the petioles are expanded into long membranous sheaths.
