One figure on the Plate shows the unopened spathe; the other has spadices with flowers and fruit. [Illustration: Pl. XI. W. Fitch lith. Ford & West Imp. ŒNOCARPUS BATAWA.

In the full-grown plant, however, the leaves preserve their regularity, the leaflets spreading out regularly in one plane and having a very beautiful appearance. The stem in old trees is fifty or sixty feet high and quite smooth, but in those growing in the shade of the forest, and in all young trees, the stem is completely hidden by the persistent bases of the decayed and fallen leaves. I have figured a tree in this state (Plate XI.). The sheathing bases of the petioles give out from their margins numerous long spinous processes of a very singular character. They are from eighteen inches to three feet long, of a black colour, flattish, and generally broken or fibrous at the point. They are much sought after by the Indians, who use them to make arrows for their “gravatánas” or blow-pipes. One of these arrows is here represented with the wicker quiver in which they are carried. They are about fifteen or eighteen inches long, sharply pointed at the end, which is covered with “curarí” poison for three or four inches down, and notched so as to break off in the wound. Near the bottom a little of the soft down of the silk-cotton-tree is twisted round into a smooth spindle-haped mass, and carefully secured with a fibre of a “_bromelia_.” The cotton just fits easily into the tube, offering a light resisting body for the breath to act upon. The fruit of this species is very similar to that of the Baccába, and is said to be of even superior flavour. The Patawá is found in the whole of the Amazon and Rio Negro in the virgin forest, though apparently nowhere very abundant. Specimens are now growing in the Palm House at Kew. The fruit is represented on Pl. X. of the natural size. ŒNOCARPUS MINOR, _Martius_. Baccába miri, _Lingoa Geral_. This is a small species common on the upper Rio Negro. The stem is not half so thick as in the _Œ. baccába_, and the leaves are in proportion. The fruit is also very small, but is very fleshy and fine-flavoured, and ripens at a different time of year from the larger kind. It grows in the dry virgin forest. My drawing of this tree was unfortunately lost on my voyage home. [Illustration: Pl. X. W. Fitch lith. Ford & West Imp. ŒNOCARPUS BATAWA. Ht. 60 Ft. ] ŒNOCARPUS DISTICHUS, _Martius_. Baccába, of Pará.
