1848.] their fruits, often useful to man, give them a never-failing interest to the naturalist, and to all who are familiar with descriptions of the countries where they most abound. The rest of the vegetation was hardly what I expected. We found many beautiful fowers and climbing plants, but there are also many places which are just as weedy in their appearance as in our own bleak climate. But very few of the forest-trees were in flower, and most of them had nothing very peculiar in their appearance. The eye of the botanist, indeed, detects numerous tropical forms in the structure of the stems, and the form and arrangement of the leaves; but most of them produce an effect in the landscape remarkably similar to that of our own oaks, elms, and beeches. These remarks apply only to the immediate vicinity of the city, where the whole surface has been cleared, and the present vegetation is a second growth. On proceeding a few miles out of the town into the forest which everywhere surrounds it, a very different scene is beheld. Trees of an enormous height rise on every side. The foliage varies from the most light and airy to the darkest and most massive. Climbing and parasitic plants, with large shining leaves, run up the trunks, and often mount even to the highest branches, while others, with fantastic stems, hang like ropes and cables from their summits. Many curious seeds and fruits are here seen scattered on the ground; and there is enough to engage the wonder and admiration of every lover of nature. But even here there is something wanting that we expected to find. The splendid Orchideous plants, so much sought after in Europe, we had thought must abound in every luxuriant tropical forest; yet here are none but a few smail species with dull brown or yellow flowers. Most of the parasitic plants which clothe the stems of every old or fallen tree with verdure, are of quite a different character, being ferns, Tillandsias, and species of Pothos and Caladium, plants resembling the Ethiopian lily so commonly cultivated in houses. Among the shrubs near the city that immediately attracted our attention were several Solanums, which are allied to our potato. One of these grows from eight to twelve feet high, with large woolly leaves, spines on both leaves and stem, and handsome purple flowers larger than those of the potato. Some other species have white flowers, and one much resembles our bitter-sweet (Solanum Dulcamara). Many handsome
