A floristic inventory was carried out in an area of palm-dominated creek forest in Jenaro Herrera, in the northeast of Peru. All trees ≥ 10 cm dbh were surveyed in a one-hectare permanent plot using the standard RAINFOR methodology. There were 618 individuals belonging to 230 species, 106 genera and 43 families. The results showed that the total basal area of the trees in the plot was 23.7 m2. The three species with the highest importance value indexes were Iriartea deltoidea Ruiz & Pav., Oenocarpus bataua Mart. (Arecaceae) and Carapa procera DC. (Meliaceae). The five most dominant families in order of importance were Arecaceae, Fabaceae, Meliaceae, Euphorbiaceae and Sapotaceae. Although the soil of this plot was poorly drained, the number of trees and the diversity of the plot were typical for terra firme forest in the western Amazon.
