This research intended to present the Floristic Composition and Phytosociological Analysis of an Araucaria Forest remainder. At the studied area, two different pedologycal units were analyzed; in each area 15 square samples (10X10) were randomly distributed. Within both units it was numbered 307 trees (pbh ≥ 15 cm), even 33 dead ones. 44 species were detected among the 274 alive individuals, belonging to 31 genus and 21 families. The most important species due to value importance (VI) were: Myrsine umbellata (71,51) Araucaria angustifolia (50,94), Podocarpus lambertii (46,42), Sebastiania commersoniana (32,52) and Myrcia multiflora (27,76).
