The objective was to describe and systematize the leaf epidermis of 10 Amazonian forest species as tools to help the taxonomy and contributing to the technical-scientific knowledge. For this, the usual techniques in plant anatomy were performed to observe, besides the stomata width, length and frequency and submitted to statistics, applying: Tukey test, ANOVA, Cluster Analysis and Principal Component Analysis. It was observed that the adaxial and abaxial epidermis have heterodimen- tional cells, with varied shape and size, rounded and sinuous, in all studied species the stomata are anomocytic and only Spondias mombin is amphiestomatic. The species Dipteryx odorata and Virola surinamensis can be easily identified due to their guard cell ornamentation. The species Alexa grandiflora and Lecythis lurida have similar structures making identification difficult. The trichomes presented varied forms, being these the best parameter for identification and distinction.
