The zuyñandỹ, a large, lofty tree, consists of a soft wood, a thick bark turgid with copious moisture, and red flowers which seem to be composed of one large expanded leaf, as soft as silk. The bark, when stripped of the rough outer skin, and properly ground, is of much efficacy in healing wounds inflicted by the teeth or claws of a tiger. THE ZAMUÛ. The zamuû is ridiculous both in name and form; for the Spaniards call it _palo borracho_, the drunken tree. It is lofty. It has a trunk surrounded with largish thorns, and bears middle-sized flowers of a beautiful red colour, but is of very singular appearance in other respects. For the highest and lowest parts of the trunk are small, while the middle swells out to a great width, like a barrel: on which account its very soft wood is easily made into tubs, and barrels. The farther this tree grows from rivers the wider it swells, so great is its dislike to water. It bears a round fruit like certain large gourds, with a very strong rind, which fruit, when ripe, bursts open and discovers woolly flakes, like cotton, and softer than silk, but with so short a fibre that it is very difficult to draw them out into a thread. The thorns of this tree when bruised to powder, and boiled, tinge the water with a red colour which is said to cure sore eyes. THE MANGAỸ. The mangaỹ is about the size of a cherry-tree, and bears white flowers, which exhale a very delightful odour. It produces fruit of a golden colour, and equal in size to a large plum, which, when ripe, are agreeable to the taste, but hurtful to the stomach. Both the tree and the fruit overflow with a kind of milky, and resinous juice, called mangaỹci, in the Guarany tongue, which streams out plentifully, when you cut the bark, and is caught by the hand, or by a board. The air curdles it, and gives it the appearance of a little skin. In this state, it is rolled up into balls, which are so remarkably elastic, that when thrown lightly upon the ground they leap up very high in the air. This liquor, mangaỹci, is said to be very useful in cases of dysentery. It is much to be lamented that so very few take the trouble to collect this rosin, which would be useful in Europe in various ways. DRAGON'S-BLOOD. The tree caà verà, which produces the dragon's-blood, is middle-sized both as to height and bulk. Some botanists call these trees _palmæ pruniferæ foliis jaccæ_, but in my opinion they have no affinity whatever with palms. When a deep incision is made into their trunks, a kind of juice flows from them, resembling blood in colour and consistence, and which, when boiled on the fire, condenses into a liver-coloured rosin. Physicians complain that foreign traders sell them goat's-blood, bolo, or red Brazil wood, mixed with gum arabic, for dragon's-blood. THE CUPAỸ.
