Part 5

The spadices grow on long stalks from the axils of the leaves and are simply branched. The spathes are ventricose, erect, persistent and prickly, and the fruit is globular, of a red colour, and not eatable.

The rind or bark of this species is much used for making the “tipitis” or elastic plaited cylinders used for squeezing the juice out of the grated Mandiocca-root in the manufacture of farinha. These cylinders are sometimes made of the rind of certain water plants and of the petioles of several palms, but those constructed of “Jacitára” are said to outlast two or three of the others, and though they are much more difficult to make, are most generally used among the Indian tribes. When the cylinders are used they are suspended from a strong pole, having been first filled with the grated pulp. A long lever is passed through the loop at the lower end of the “tipiti,” by means of which it is stretched, the power being applied by a woman sitting on the further extremity of the pole. The cylinder thus becomes powerfully contracted, and the poisonous juice runs out at every part of the surface and is caught in a pan below in order to be carefully thrown away, for it would cause speedy death to any domestic animal which should drink it.

This species grows in the Catinga forests of the Upper Rio Negro and on the margins of small streams, climbing over trees and hanging in festoons between them, throwing out its armed leaves on every side to catch the unwary traveller. How often will they seize the insect-net of the ardent Entomologist just as he is making a dash at some rare butterfly, or fasten in his jacket or shirt-sleeve, or pull the cap from his head! Woe then to the impatient wanderer! a pull or a tug will inevitably cause a portion of the fractured garment to stay behind, for the “jacitára” never looses its hold, and it is only by deliberately extracting its fangs that the intruder can expect to depart unhurt.

In some places small igaripés or forest streams are almost filled up with various climbing grasses and creepers, among which the “jacitára” holds a prominent place, and it is up these streams that the Indians often delight to fix their abode. In such cases they never cut down a branch, but pass and repass daily in their little canoes which wind like snakes among the tangled mass of thorny vegetation. They are thus almost safe against the incursions of the white traders, who often attack them in their most distant retreats, carry fire and sword into their peaceful houses and take captive their wives and children. But few white men can penetrate for miles along a little winding stream such as is here described, where not a broken twig or cut branch is found to show that a human being has ever passed before. Thus does the thorny “jacitára” help to secure the independence of the wild Indian in the depths of the forests which he loves.

This species most nearly agrees with the _D. macroacanthus_ of Martius. Fine specimens of an allied species may be seen growing in the Palm House at Kew.

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

Genus BACTRIS, _Jacquin_.

Male and female flowers intermingled in the same spadix, the females being more abundant in the lower parts and the males in the upper. Spathe double, exterior short and membranous, interior complete, woody. Male flowers with six, nine or twelve stamens. Female flowers with three sessile stigmas, and the stamens represented by a rudimentary ring.

The stems in this genus are very slender, ringed, nearly smooth or with a few scattered spines. The leaves are more or less terminal, generally few in number, pinnate or entire, with the bases of the petioles much sheathing and very spiny. The spathe is also clothed with spines. The spadices are simple or simply branched and grow from the axils of the leaves. The fruit is small and round, and the outer pulp is often subacid and eatable.

This very extensive genus of small prickly Palms contains forty-six species, all natives of South America. Two species described by Martius are here figured, together with six others apparently new, but as it may be impossible to identify those not seen in fruit, some of them have been left unnamed.

The species here figured are all from the Rio Negro, where I began studying them, and are sufficient to give an idea of their general characteristics and aspect.

PLATE XXVIII. BACTRIS PECTINATA, _Martius_.

Iú, _Lingoa Geral_.

The stem of this species is from six to ten feet high, very slender, strongly ringed or jointed and smooth, but all other parts of the plant, the petioles, sheaths, spathes, &c., are prickly. The leaves are regularly pinnate, with the leaflets long, narrow, pointed and hairy beneath. The long sheathing bases of the petioles are persistent, covering the stem often half way down to the ground.

The spadices grow from among the persistent leaf-sheaths; they are very small, simple or two- or three-branched, and have a small persistent fibrous spathe. The fruit is very small and globular and of a red colour, and is not eatable.

This very hairy and prickly little palm grows in the sandy Catinga forest of the Upper Rio Negro and in the most exposed localities. It seems to agree well with the _B. pectinata_ of Martius.

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

PLATE XXIX. BACTRIS ——, n. sp.

Marayarána, _Lingoa Geral_.

The stem of this species is about an inch in diameter and ten or twelve feet high, thickly set with flat black spines disposed in rings. The leaves are rather large and irregularly pinnate, the leaflets being in little groups of two or four, standing out at various angles from the midrib, the groups themselves being set alternately along it. The leaflets are elongate and have the midrib produced in a bristly point, and the terminal pair are not larger than the rest. The petioles are armed with flat whitish spines, which on the long sheathing bases become black.

I met with this palm only once, growing in the dry virgin forest on the banks of the Rio Negro. Though it had neither flowers nor fruit at the time, yet its habit is so peculiar as to leave little doubt of its being a new species. It seems most nearly allied to the _Bactris macroacantha_ of Martius.

PLATE XXX. BACTRIS ELATIOR, n. sp.

Marayarána, _Lingoa Geral_.

This is a tall and elegant species. The stem is from fifteen to twenty feet high and about one inch in diameter, with a few scattered groups of small spines. The leaves are regularly pinnate, with broad leaflets narrowed at the base and ending in a lengthened point, the terminal pair being rather broader. The petioles and their sheathing bases are covered with broad, flat, whitish spines.

The spadices grow from among the lower leaves on long stalks and are simply branched and drooping. The spathes are elongate fusiform and spiny, and are persistent. The fruit is small and globular.

This very graceful palm grows in the moist part of the virgin forest of the Upper Rio Negro, where I found it on the banks of small forest streams; and it seems quite distinct from any of the very numerous species described by Martius.

PLATE XXXI. BACTRIS ——, n. sp.

Native name unknown.

The stem of this curious palm is from twenty to twenty-five feet high and very slender. It is marked with slightly sunk rings and has a few scattered spines. The leaves are rather small, few in number and terminal. The leaflets are rigid, narrowed at the base, widest near the end and suddenly tapering to a point. They are arranged in groups of three or four at short intervals along the midrib, from which they stand out at different angles. The petioles and their sheathing bases are thickly set with slender, flattish, black spines generally pointing downwards.

This species was only found once, growing in the “gapó” or flooded lands of the Upper Rio Negro, and at the time had neither flowers nor fruit. The form and arrangement of the leaflets are so peculiar that it cannot be confounded with any species yet described.

A leaflet is represented of a larger size to show the peculiar form.

PLATE XXXII. BACTRIS MACROCARPA, n. sp.

Iú, _Lingoa Geral_.

This species has the stem about an inch in diameter and ten or twelve feet high, distinctly jointed, smooth and reed-like, but with a few spines in small groups at the joints. The leaves are terminal, of moderate size and rather interruptedly pinnate. The leaflets often grow in pairs and are broad, narrowed at the base and have the midrib produced at the point, the terminal pair being the largest. The petioles and sheaths are thickly set with whitish flat prickles.

The spadices are small, five- or six-branched, and rather long-stalked. The spathe is small, smooth and persistent. The fruit is oval, with a produced apex, large in proportion to the tree, of a reddish or yellowish olive colour, and not eatable, the outer covering being dry and woolly.

The smooth reed-like stem of this species resembles those of the Geonomas, and it is also remarkable for the large size of its fruit. It grows on the dry sandy soil of the Catinga forests of the Upper Rio Negro. It seems most nearly allied to _B. mitis_ of Martius.

A fruit is represented on the Plate of the natural size, and a leaflet reduced one-fourth to show the peculiar form.

PLATE XXXIII. BACTRIS TENUIS, n. sp.

Iú, _Lingoa Geral_.

In this species the stem is not thicker than a goose quill, distinctly jointed and smooth. The leaves are terminal, four or five in number, and rather irregularly pinnate. The leaflets are elongate and acute, with produced points, four or five in number, on each side of the midrib, the terminal pair being the broadest. The petioles and their sheathing bases are covered with small, flat, black spines.

The spadices grow from below the leaves and are very small and unbranched. The spathes are fusiform, erect, persistent and smooth. The fruit is small, globose, and of a red colour.

This is one of the smallest of Palms, and in every part of its structure offers a striking contrast to the great _Mauritia_ and other giants of the family. While they possess huge columnar stems a hundred feet in height and two feet in diameter, this has but a slender stalk the thickness of a quill; and while their fruit bunches are the largest in the vegetable kingdom, the whole spadix of this species is smaller than a bunch of currants.

It is allied to _B. cuspidata_ and to _B. fissifrons_ of Martius, but seems sufficiently distinct from either of them. It grows exposed to the sun in the sandy Catinga forests of the Upper Rio Negro.

An entire spadix with fruit is represented on the Plate, of the natural size.

PLATE XXXIV. BACTRIS SIMPLICIFRONS, _Martius_.

Iú, _Lingoa Geral_.

The stem of this little palm resembles in size and appearance that of _B. tenuis_. The leaves are five or six in number, terminal, and consist of a single broad bifid leaflet, or more properly a pair of opposite terminal leaflets. The petioles and their sheathing bases are thickly set with spines.

The spadices grow from below the leaves; they are unbranched and bend downwards, and the spathes are elongate, small, erect or horizontal, smooth and persistent.

This pretty little species seems identical with one described by Martius under the name of _Bactris simplicifrons_. It is not uncommon in the dry Catinga forests of the Upper Rio Negro.

BACTRIS MARAJA, _Martius_.

Marajá, _Lingoa Geral_.

This is a palm rather larger than most others of the genus, and inhabiting the flooded banks of the Amazon.

It produces large clusters of fruit resembling small black grapes, and having a thin pulp of an agreeable subacid flavour,—a peculiarity not found in the fruit of any other American palm that I am acquainted with. The places where it grows are often so deeply flooded that the fruit hangs close to the surface of the water, and can be plucked while passing in a canoe.

Dried specimens of the tree and fruit are in the Museum, and young plants are growing in the Palm House at Kew.

PLATE XXXV. BACTRIS INTEGRIFOLIA, n. sp.

Iú, _Lingoa Geral_.

This beautiful species has the stem hardly so thick as the little finger, and nine or ten feet high, smooth and distinctly jointed. The leaves are four or five in number, terminal, entire, three or four times as long as they are wide, and not very deeply bifid at the end. The petioles and their sheathing bases are thickly set with long, flat, black spines.

The spadices are very small, erect and two-branched, growing from among the persistent sheathing bases below the leaves. The spathes are small, erect and persistent, clothed with adpressed brown spines. The fruit is small and globular, and of a black colour.

This palm was found at S. Carlos on the Upper Rio Negro and on the “Estrada de Javita,” a road through the forest for ten miles, which connects the river-systems of the Rio Negro and Orinoco, and along which most of the traffic between Venezuela and Brazil passes. In both cases it grew in the shady virgin forest.

Genus GUILIELMA, _Martius_.

Male and female flowers mixed in the same spadix, bracteate. Spathe double; exterior bifid; interior complete, woody. Male flowers with six stamens and a rudimentary pistil. Female flowers with three sessile stigmas, but with no rudiments of stamens.

The stems are lofty, rather slender, and armed with dense black cylindrical spines disposed in regular rings. The leaves are terminal and pinnate, but in the young plants entire, and the petioles are very spiny. The spadices are simply branched, growing from beneath the leaves, and the fruits are large, ovate, fleshy or mealy and eatable.

Three species only of this genus are known, inhabiting the lower mountain ranges of Peru and New Granada. They are lofty and conspicuous Palms with a remarkably handsome crown of foliage. One species only is found in the Amazon district, in all parts of which it is commonly cultivated.

PLATE XXXVI. GUILIELMA SPECIOSA, _Martius_.

Pupúnha, _Lingoa Geral_. Pirijao, _Indians of Venezuela_, Humboldt. “The Peach Palm.”

This most picturesque and elegant palm has the stem slender, cylindrical, and thickly set with long needle-shaped spines disposed in rings or bands. It reaches sixty feet in height, and grows quite erect, though in exposed situations it becomes curved and waving. The leaves are very numerous, terminal, pinnate and drooping, forming a nearly spherical crown to the stem; and the leaflets growing out from the midrib in various directions, and being themselves curled or waved, give the whole mass of foliage a singularly plumy appearance. The young plants have the leaves entire like those of the Bussú, but as the age of the tree increases they break up into regular narrow leaflets.

The spadices grow from beneath the leaves, and are small, simply branched and drooping. The spathes are ventricose, woody and persistent, curving over the spadix.

The fruit is about the size of an apricot, of a triangular oval shape, and fine reddish-yellow colour. In most instances the seed is abortive, the whole fruit being a farinaceous mass. Occasionally, however, fruits are found containing the perfect stony seed, and they are then nearly double the usual size. This production of undeveloped fruits may be partly due to change of soil and climate, for the tree is not found wild in the Amazon district, but is invariably planted near the Indians’ houses. In their villages many hundreds of these trees may often be seen, adding to the beauty of the landscape, and supplying the inhabitants with an abundance of wholesome food. In fact it here takes the place of the cocoa-nut in the East, and is almost as much esteemed.

As the stems are so spiny, it is impossible to climb up them to procure the fruit in the ordinary way. The Indians therefore construct rough stages up the sides of the trees, or form rude ladders by securing cross pieces between two of them, by which they mount so high as to be able to pull down the bunches of fruit with hooked poles.

The fruits are eaten either boiled or roasted, when they somewhat resemble Spanish chestnuts, but have a peculiar oily flavour. They are also ground up into a kind of flour, and made into cakes which are roasted like cassava bread; or the meal is fermented in water and forms a subacid creamy liquid. Parrots, macaws and many other fruit-eating birds devour them, and tame monkeys eat them greedily, though the wild ones cannot climb the spiny stems to obtain them.

The wood of this tree when old and black is exceedingly hard, turning the edge of any ordinary axe. When descending the River Uaupes in April 1852, I had a number of parrots whose objections to any restraint upon their liberty caused me much trouble. Their first cage was of wicker, and in a couple of hours they had all set themselves at liberty. Then tough green wood was tried, but the same time only was required to gnaw that through. Thick bars of deal were bitten through in a single night, so I then tried the hard wood of the Pashiúba. This checked them for a short time, but in less than a week by continual gnawing they had chipped these away and again escaped. I now began to despair; no iron for bars was to be procured and my resources were exhausted, when one of my Indians recommended me to try Pupúnha, assuring me that if their beaks were of iron they could not bite that. A tree was accordingly cut down and bars made from it, and I had the satisfaction of seeing that their most persevering efforts now made little impression.

The very sharp needle-like spines of this tree are used by some tribes to puncture the skin, in order to produce the tattooed marks with which they decorate various parts of their bodies. Soot produced from burning pitch rubbed into the wounds is said to make the indelible bluish stain which these markings present.

This palm appears to be indigenous to the countries near the Andes. On the Amazon and Rio Negro it is never found wild. It is mentioned by Humboldt as having a smooth polished stem, which is a mistake.

Very fine specimens of this tree are growing in the great Palm House at Kew.

Plate III. fig. 4. represents a fruit of the natural size.

Genus ACROCOMIA, _Martius_.

Female flowers in the inner, male flowers in the outer part of the same spadix. Spathe complete, woody. Male flowers with six stamens and a rudimentary pistil. Female flowers with a short style and three stigmas, and a ring of abortive stamens.

The stems of these Palms are tall, strong, and more or less prickly. The leaves are large, pinnate, much drooping, and forming a dense spherical head of foliage. The leaflets are linear, and with the petioles are very prickly. The spadix is simply branched, and the fruit is round or oval, of an olive-green colour, and has a firm fleshy outer covering, which is often eaten.

Eight species of this genus are known, inhabiting various parts of South America, but more particularly Brazil. One or perhaps two species are found at Pará, but none on the Upper Amazon, where the alluvial soil and dense forests are unsuited to their growth.

PLATE XXXVII. ACROCOMIA LASIOSPATHA, _Martius_.

Mucujá, _Lingoa Geral_.

The stem of this tree is about forty feet high, strong, smooth and ringed. The leaves are rather large, terminal and drooping. The leaflets are long and narrow, and spread irregularly from the midrib, every part of which is very spiny. The sheathing bases of the leaf-talks are persistent on the upper part of the stem, and in young trees clothe it down to the ground.

The spadices grow from among the leaves, erect or somewhat drooping, and are simply branched. The spathes are woody, persistent and clothed with spines. The fruit is the size of an apricot, globular, and of a greenish olive colour, and has a thin layer of firm edible pulp of an orange colour covering the seed.

This species is common in the neighbourhood of Pará, where its nearly globular crown of drooping feathery leaves is very ornamental. The fruit, though oily and bitter, is very much esteemed and is eagerly sought after. It grows on dry soil about Pará and the Lower Amazon, but it is quite unknown in the interior.

Several young plants of this and a species closely resembling it, the _A. sclerocarpa_, are growing in the Palm House at Kew, and in the Museum at the same place are specimens of the stem and fruit sent by Mr. Bates and myself from Pará.

Martius mentions the _A. sclerocarpa_ only as being found at Pará, but his description of the other species agrees best with the tree here figured. The two, however, seem very closely allied, if they are really distinct species.

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

Genus ASTROCARYUM, _Meyer_.

Female flowers few in number, situated beneath the males on the same spadix. Spathe complete, woody. Male flowers with six stamens and a rudimentary pistil. Female flowers with three stigmas and a rudimentary ring of stamens.

In this genus the stems are generally lofty and thickly set with rings of spines, but some species are stemless. The leaves are large and pinnate, the leaflets elongate and linear, and as well as the petioles very prickly. The spadices are simply branched, and the fruits are ovate or globose, with a fibrous or fleshy covering, sometimes eatable.

Sixteen species of these Palms are known, inhabiting Mexico, Brazil, and other parts of South America, but not extending higher up the mountains than 2000 feet above the sea. They have rather a repulsive aspect, from almost every part,—stem, leaves, fruit-stalk and spathe, being armed with acute spines in some cases a foot long.

PLATE XXXVIII. ASTROCARYUM MURUMURÚ, _Martius_.

Murumurú, _Lingoa Geral_.

This palm has the stem from eight to twelve feet high, irregularly ringed, and armed with long scattered black spines. The leaves are terminal and of moderate size, regularly pinnate, the leaflets spreading out uniformly in one plane, elongate, acute, with the terminal pair shorter and broader. The petioles and sheathing bases are thickly covered with long black spines generally directed downwards, and often eight inches long.

The spadices grow from among the leaves and are simply branched and spiny, erect when in flower, but drooping with the fruit. The spathes are elongate, splitting open and deciduous. The fruit is of a moderate size, oval, of a yellowish colour, and with a small quantity of rather juicy eatable pulp covering the stony seed.
