Palm trees of the Amazon and their uses

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.

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.
