Part 7

The trees of this genus also furnish another article of food. The undeveloped leaves in the centre of the column form a white sweetish mass, which when boiled somewhat resembles artichoke or parsnep, and is a very good and wholesome vegetable. It may also be eaten raw, cut up and dressed as a salad with oil and vinegar. As, however, to obtain it the tree must be destroyed, it is not much used in Pará, except by travellers in the forest who have no particular interest in the preservation of the trees for fruit. The Cabbage Palm of the West Indies is an allied species, and is used for food in the same manner.

Very fine specimens of this tree may be seen in the great Palm House at Kew, where they grow almost as luxuriantly as in their native forests.

In the Plate, the unopened spathe, flower-spadix and fruit are represented, as they are often found, together on the same tree.

EUTERPE ——?

On the banks of the Rio Negro there appears to be another species of this genus, closely allied to the Euterpe oleracea, but the stem is thicker and straighter, the whole tree larger, and the leaf-column thicker, and of a clear green colour. It grows on the dry land of the virgin forest, or sometimes within the limits of the winter’s inundations. I unfortunately neglected to examine into its peculiar characters, as until my return to Pará I had considered it identical with the species so common there.

I was also informed that in the island of Marajó there is a species or variety having white fruit, but I had no opportunity of examining it.

EUTERPE CATINGA. Ht. 40 Ft. ]

PLATE VIII. EUTERPE CATINGA, n. sp.

Assaí de catinga, Lingoa Geral.

This species differs from the last in its slenderer stem and less drooping leaves and leaflets. It grows to forty or fifty feet high. The spadices are fewer and much smaller. The fruit also is smaller, and has more pulpy matter, so that a small quantity of it makes more of the “vinho d’Assaí” (the Assaí wine) than the same quantity of fruit of the larger kind. The column formed by the sheathing bases of the leaves is smaller than in the last species, and always of a red colour. The roots rise considerably above the ground, forming a distinct cone, which is not the case in the E. oleracea. It inhabits the forests on a dry sandy soil, of the Upper Rio Negro. These districts are called Catinga forests by the natives, and have very peculiar vegetable productions, differing almost entirely from those of the lofty virgin forest.

The preparation of the fruit of this species is sweeter and more finely flavoured than that of any other, and is therefore much sought after, but it takes the produce of four or five trees to yield as much as a single spadix of the larger kind will often produce. I found the fruit ripe in the month of April on the river Uaupés, a branch of the Rio Negro above the Falls.

GENUS ŒNOCARPUS, Martius.

Male and female flowers on the same spadix, the former most abundant. Spathe double, the interior complete, woody, and deciduous. Flowers without distinct bracts; the male with six stamens and rudiments of a pistil, the female with three sessile stigmas, but with no rudiment of stamens.

These are tall majestic trees with large smooth stems, generally distinctly ringed. The leaves are large, terminal, more or less regularly pinnate, and have the bases expanded and clasping the stem, but not forming a sheathing column as in the last genus. The spadices spring from beneath the leaves and are simply branched; the branches are very lax, hanging down vertically except when forced outwards by the ripening fruit. The spathe is very large, fusiform and woody, and falls off the moment the spadix escapes from it. The fruit is small, nearly globular, and has an edible pulpy covering, like that of the genus Euterpe.

Six species only are known, and all inhabit tropical America, where they prefer dry, slightly elevated lands, none being known to extend more than 1600 feet above the sea.

ŒNOCARPUS BACCABA Ht. 50 Ft. ]

PLATE IX. ŒNOCARPUS BACCÁBA, Martius.

Baccába, Lingoa Geral.

This is a smooth thick-stemmed handsome tree, faintly ringed, and reaching fifty or sixty feet in height. The leaves are large, terminal, and pinnate. The leaflets are long; gradually pointed, and set at equal distances along the midrib. When young, the leaves are flat, the leaflets or pinnæ all standing out in the same plane; but in the full-grown tree the leaflets are in groups of two or three standing out at different angles from the general plane of the leaf, so as to give an irregular mixed appearance to the leaf. The petioles are greatly dilated at the base where they clasp the stem, and have a fibrous margin. The leaves as they die fall clean off from the stem, no part of the base remaining. The spathe is deciduous, being comparatively seldom visible. The fruits are of a violet or black colour when ripe, but are covered with a dense whitish bloom. They are prepared in the same way as the Assaí, but the pulp is of a pinkish cream-colour instead of purple, and the liquid is more oily, and of delicious flavour, somewhat resembling filberts and cream. It is said, however, not to be so wholesome as the Assaí, and in districts where intermittent fevers are prevalent, to bring them on, and to be particularly hurtful to persons recovering from that disease. A very beautiful oil is sometimes extracted from the pulp by pressure; it is perfectly clear, liquid, and inodorous; and serves as a substitute for olive oil, as well as being very good for lamps. The leaves are sometimes used for thatching when none better can be obtained; but owing to the irregularity of the pinnæ before mentioned, they are not much used.

This species inhabits the dry virgin forests of the Rio Negro and Upper Amazon. In the lower parts of that river and in the neighbourhood of Pará it is replaced by another species, the Œnocarpus distichus.

The Œ. baccába is growing at Kew.

One figure on the Plate shows the unopened spathe; the other has spadices with flowers and fruit.
