  • Introduction

    The heterogeneous landscape of the Botanical Garden's arboretum reflects the many historical interventions by men who wished to turn the institution into a center of dissemination for agronomy, botany and conservationism. In the early days of the institution, the directors were concerned with the creation of a standard to acclimatize and disseminate useful plants. Afterwards, there was a long period in which the goal at the arboretum was to turn the plant collection into a scientific collection dedicated to taxonomic research and educational activities towards the recognition of the plant diversity.

    The cultivated area currently holds, out of the greenhouses, around 9 thousand botanical specimens belonging to around 1,500 species. At the plant beds, there are mostly bushy species mostly of the families Leguminosae, Arecaceae, Myrtaceae and Bignoniaceae. Of the total, only 30% belongs to the national flora. In the greenhouses and the thematic collections, however, it is the opposite. The collections of orchids and bromeliads together add up to more than 8 thousand vases and more than a thousand species, most of which are Brazilian and obtained in botanical expeditions by researchers of the Botanical Garden during the last 30 years.

    There are pergolas and arbors spreading throughout the arboretum, sustaining vines that represent an important part of the scientific collection, since there is plenty of data stored on the files of the institution on them. Bignoniaceae, Passifloraceae and Convolvulaceae are the most important vine families, and many specimens still existing in the arboretum nowadays were subjects of the taxonomic studies of Barbosa Rodrigues and other important botanists. Some of those specimens are typus of species discovered at the time. The same is true for other sub-collections such as the palm trees of the Arecaceae family, species of the Acanthaceae family and fig trees of the Moraceae family.
