Catalogue of the Vascular Plants of the
Antioquia Department, Colombia

Antioquia is one of the 32 departments of Colombia and it lies in the northwestern corner of the country (Figure 1). It is bordered to the north by the Córdoba and Bolívar departments, to the northeast by the Caribean sea in the locality known as Golfo de Urabá, to the west by the Chocó department, to the south by the departments of Caldás and Risaralda and to east by the departments of Boyacá, Santander and Bolívar.

Compilation of the vascular plants of the Antioquia department has been possible thanks to a colaborative agreement between the Universidad de Antioquia (Medellín, Colombia) y el Missouri Botanical Garden (St. Louis, MO, USA), and to the contribution of more than 70 botanists from about 25 national and international institutions.

About 8,302 species of vascular plants have been registered in the department of Antioquia, which represents 33.5% of the 27,000 estimated species for Colombia (Bernal, 2002; Bernal et al., 2007). On the other hand, the endemic species add up to 580, which is about 5.52% of the 10,500 estimated for the country (Bernal 2009).

In Colombia, Antioquia is considered as one of the departments that is better sampled; but still has several largely unexplored regions, as seen in the preliminar representation of the distributions and densities of the collections recorded in the department (Figures 3, 4). On the other hand, the better sampled areas are the ones that exhibit higher number of species (Figure 5).

The Antioquia department comprises an area of 63,612 km2, and is dissected by the Central and Western mountain ranges, and three major rivers: the Cauca river that flows between the two cordilleras, the Magdalena river, adjacent to the eastern slope of the Central Cordillera, and the Atrato River which covers the lowlands forest in the western part of the Department. Due to the convergente of these several factors, the Antioquian territory presents a wide altitudinal and topographical variation, in addition to a pronounced variation in rainfall that ranges from 1,000 mm in several regions of the Cauca y Magdalena valleys, and up to about 6,000 mm in the Río Atrato valley (Callejas, 2011). Moreover, the broad variations in climate and rainfall result in the diverse vegetation covers found in Antioquia (Figure 2), where we observe at least 10 different vegetation zones (Holdridge, 1967).

The printed version of the Catalogue published in September 2011, consists of two volumes. Volumen I includes information on the generalities regarding the Department, such as relief, soils, life zones and the history of the botanical exploration in Antioquia. While the second volumen presents floristic analyses of the vegetation, the extinction estimates of the arboreal and shrubby species, and the annotated list of the vascular plants of the Department.

The online version of the Catalogue presents the information for each of the species found in Antioquia in a single page. Each species’ page includes the original publication, synonyms (as accepted by the author of the respective treatment). The page also includes information on the habit of the species, uses, common names (when available), altitudinal ranges, distribution by municipalities, and its presence in the physiographic zones as well as in the life zones. A representative voucher is cited for each accepted species. Information on the type is also included if this was collected in Antioquia. Finally, infraspecific categories are also listed if they are present.
