PHYTOLOGY.--This province affords a variety of timber for the purposes of building, cabinet-work, and dying. The tree called here _anduassu_ is nearly fifteen feet high, and two in diameter, grows rapidly, and only in the vicinity of the sea. The Indians make an aperient medicine from its fruit, with which they cure the dropsy. Oil is extracted from it for burning lights, and for the composition of blue ink, and a blue dye. The _tatagyba_, which is the _morus tinctoria_ of Linneus, affords an excellent yellow dye, extracted by the boiling of its wood in water, with the addition of a portion of alum. The _grumixameira_ is a tree which produces a most excellent fruit, similar to a cherry in appearance, but of a finer flavour. I brought some of its seed to England, but am yet uncertain whether it will prosper in our climate. A small tree produces a clove, said to be superior to that of the Moluccas. The camphor tree, the cane of Madagascar, some African grasses, and a delicate species from Hindostan, have been recently naturalized here. Canes of such thickness and height grow upon the margins of the Suruhy, that ladders are made of them to hang the highest temples with decorations for festivals. In many situations ferns are met with, not differing in the least from those of Europe, except in the immense quantities which grow in uncultivated grounds. In the woods adjacent to Andrahi, near the road leading to the cascades of Tejuco, there is one which has grown, amongst other vegetation of wild trees and brushwood, to the perpendicular height of eighteen feet. In some woods, a sort of almond tree is met with, with fruit almost spherical, and of the magnitude of a hen’s egg. Cocoa trees are not very abundant, owing to an insect which gnaws the sprout after it grows to any size, and prevents their arrival at the perfection they otherwise would. European horticulture succeeds better here than in the northern provinces. The mango tree is only abundant in the suburbs of the capital, and rarely fructifies to perfection. Oranges grow spontaneously, and consist of various sorts; the selectas, which are large, and the tangerinas, both of the most delicious qualities. The coffee tree, having been naturalized here, during the government of Conde de Bobadella, by the attention and care of a magistrate, multiplies prodigiously, and is now one great branch of the riches of this province. The cotton tree does not prosper universally. Apple, pear, cherry, and apricot trees do not succeed. Fig trees grow rapidly, and produce fruit in perfection; but they have an enemy in a little insect, which introduces itself very frequently into the pith, and dries it up. Amongst an infinity of other productions may be enumerated jalap, ipecacuanha, called here _poaya_, trees of gum, of _sangue de drago_, (blood of dragon,) of oil of capaiba, and of Peruvian balsam. The cultivation of cochineal is now little attended to.
