The aim of the study was to determine floristic composition using nine 0.1-ha transects in the riparian premontane forest of La Genova gorge , located in the Regional Development Institute Genova, La Merced District, Chanchamayo Province in Peru. The main goal of this study is to contribute to the knowledge and valorization of riparian forest of the Central Andes in Peru. This study was based on analysis, distribution, diversity, floristic and structural composition, in an altitude gradient (low, mid and high level). Furthermore, dendrological and forest mensuration data were recorded, for shrubs and trees from 2.5 cm and 0.30 m diameter at breast height (DBH), respectively. Floristic composition of nine 0.1 ha transects was represented by a total of 143 species, 2069 individuals, 14 morpho species, and 30 mono individual families. The most abundant families were Piperaceae, Fabaceae, Euphorbiacea and Moraceae. The dominant taxa were Piper hispidum, Trophis caucana, Piper reticulatum, Costus sp.1 and Sapium glandulosum. The Genera better represented were Acalypha, Piper, Costus, Trophis and Sapium. The floristic composition was also analyzed according to an altitude gradient, and the results are as follows: - Low altitude: T1, T2 and T3 (800- 950m ) 476 individuals, 77 species, 10 mono specific species and 19 mono individuals species were found. Most abundant families were: Euphorbiaceae, Moraceae, Fabaceae and Piperaceae. Those species with high number of individuals, in ascending order were: Piper hispidum, Trophis caucana, Piper reticulatum, Costus sp.1, Sapium glandulosum. The Genera better represented, in descending order, were Piper, Acalypha, Costus, Trophi and Geonoma. - Mid altitude: T4, T5 and T9 (1000-1050m) A total of 903 individuals, 92 species, 40 mono specific species and 29 mono individual species were found. Most abundant families were Fabaceae, Moraceae, Euphorbiaceae and Myrsinaceae. In ascending order, those species with highest number of individuals were Piper hispidum, Trophis caucana, Sapium glandulosum, Myrsine guianensis y Piper reticulatum. The Genera better represented in descending order were Piper, Trophis, Sapium and Inga. - High altitude: T6, T7 and T8 (1070 – 1120 m), A total of 680 individuals, 88 species, 11 mono specific species, and 30 mono individual species were found. Most abundant families were Fabaceae, Euphorbiaceae, Moraceae, Piperaceae and Urticaceae. In descending order, most abundant species were Trophis caucana, Piper reticulatum, Costus sp.1, Piper hispidum and Sapium glandulosum. The Genera better represented in descending order were Acalypha, Piper, Costus, Trophis and Sapium. Shannon indices showed highest species diversity values for transects T2, T7 and T8, the first belonging to the low altitude level and the rest to the highest altitude level. A comparative correspondence analysis with another study carried out in a nearby area, showed a great similarity in terms of floristic composition. Furthermore, our analysis found Genera Piper to be the most abundant in the riparian premontane forest of La Genova gorge.
