Part 20

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.

On the Upper Amazon cattle eat the fruits of the Murumurú, wandering about for days in the forest to procure it. The hard stony seeds pass through their bodies undigested and become thickly scattered over the pastures adjoining the houses. They are so hard that it is almost impossible to break them, except by a very hard blow with a large hammer. The internal albumen or kernel is also excessively hard, nearly approaching to vegetable ivory. Yet pigs are very fond of these little cocoa-nuts, and on one estate on the Upper Amazon where I was staying, they had scarcely anything else to eat during a part of the year but those which had passed through the stomachs of the cows. They might constantly be seen cracking the shell with their powerful jaws, and grinding up the hard kernels, on which the teeth of few other animals could make any impression. They not only existed on this food, but in some cases got actually fat upon it. The black vultures (Cathartes) occasionally eat the outer covering of this and other palm fruits, when hard-pushed for food.

This tree grows on the tide-flooded lands of the Lower Amazon and on the margins of the rivers and gapós of the Upper Amazon, though it is possible that the two may be distinct species. The specimen figured is from near Pará. There are living plants in the Palm House at the Royal Kew Gardens.

A portion of a leaf is enlarged to show the spines, and a fruit is represented of the natural size.

Mumbáca, Lingoa Geral.

This species has a rather slender stem about fifteen feet high, covered with long, flat, black spines, arranged in regular rings and pointing downwards. The leaves are terminal, rather large and pinnate. The leaflets spread regularly in one plane, and are elongate and acute, the terminal pair being rather shorter and broader. The bases of the petioles are broadly sheathing, and are all densely spiny.

The spadices grow from the bases of the lower leaves, and are erect when in flower, but hang down with the ripe fruit, which grows in a dense cluster at the end of the long stalk which is very spiny, as is also the elongate persistent spathe. The fruit is small, ovate, of a red colour and not eatable.

This palm grows in the virgin forests of the Upper Rio Negro, and a nearly allied or perhaps identical species is common about the city of Pará.

Tucúm, Lingoa Geral.

This is a lofty tree, the stem growing to a height of forty or fifty feet, with a diameter of six or eight inches. It is covered with regular broad bands or rings of thickly set black spines, with narrow spaces between them. The leaves are terminal, large and regularly pinnate. The leaflets are elongate, regularly spreading and drooping. The midrib and expanded sheaths of the petioles are densely clothed with long, flat, dusky spines, having a pale expanded margin. The edges of the leaflets are also armed with fine spines.

The spadix is erect and simply branched, and is often hid among the foliage. The spathe is persistent, and the fruit is oval, of a greenish colour and not eatable.

Every part of this palm bristles with sharp spines so as to render it difficult to handle any portion of it; yet it is of great importance to the Indians, and in places where it is not indigenous, is cultivated with care in their mandiocca fields and about their houses, along with the “Pupúnha” and other fruit trees. Yet they use neither the fruit, the stem, nor the full-grown leaves. It is only the unopened leaves which they make use of to manufacture cordage, superior in fineness, strength and durability to that procured from the Mauritia flexuosa. They strip off the epidermis and prepare it in the same manner as described in the account of that species, but while the “mirití” is principally used for hammocks, the “tucúm” serves for bow strings, fishing-nets and other purposes where fineness, combined with strength, is required. Some of the tribes on the Upper Amazon, however, make all their hammocks of “tucúm,” which renders it probable that the Mauritia flexuosa does not grow there.

The Brazilians of the Rio Negro and Upper Amazon make very beautiful hammocks of fine “tucúm” thread, knitted by hand into a compact web of so fine a texture as to occupy two persons three or four months in their completion. They then sell at about £3 each, and when ornamented with the feather-work borders, at double that sum. Most of them are sent as presents to Rio de Janeiro.

Dr. Martius has mistaken the species from which this cordage is manufactured, stating it to be the “Tucumá,” which, though very nearly allied, is never used for the purpose. The close resemblance of the native names is probably what led to the mistake, though they are never confounded by the Brazilians.

The “tucúm” is found on the “terra firme” or dry forest land of the Amazon and Rio Negro. It is growing in the Palm House at Kew.
