Abstract:We present the floristic inventory and structural analysis of vascular plants in two sectors of the tropical rainforest in Paramillo National Natural Park, in the flooding zones of the Serrania de San Jerónimo, with the aim of extending knowledge of flora in Córdoba department and offering a first approximation to the plants of the Park?s lowlands. Seventyfour families, 176 genera and 250 species (26 monoconts and 224 dicots) were found. At the floristic level, the Rubiaceae family is the most diverse with 34 species and 22 genera, followedby Arecaceae (17/9), Moraceae (15/8), Mimosaceae (12/4) and Caesalpinaceae (10/6). The calculation of structural indexes and variables, allowed us toidentify that there isn?t a pronounced dominance of one single species in these forests but that a group of species show major structural importance. Weidentified ecosistemic similarity of the forests described here with forests dominated by Dipteryx, Brosimum and Oenocarpus reported by Rangel-Ch. (2004) andforests of Anacardium excelsum reported by Zuluaga (1987) and Rangel-Ch. (ibíd.). Moreover, the forests dominated by Peltogyne purpurea, aside from beinga new record for Córdoba department, become one of the last remaining areas where this species is well preserved. There are seven species in some degreeof threat, according to UICN categories, reported in this area, two of which are new species for Córdoba; these are Cariniana pyriformis and Reinhardtiakoschnyana in critical danger. A total of 223 common names and 140 useful plants species recognized for the community were recorded, Arecaceae being thefamily with most useful species (15).
