Vegetative characterization and key of Myrtaceae species from a remnant of Araucaria Rainforest, Curitiba, Paraná

Abstract Myrtaceae is a plant family with outstanding diversity in the neotropics, which species are of difficult identification. Thus, for differentiation between to be possible, targeted inventories and detailed descriptions necessary, develop accessible reliable identification tools. The goal this research quantify richness describe vegetative characters from Araucaria Rainforest remnant, through patterns elaboration an dendrological key. For characterization trunk bark, up five healthy adult individuals each were selected, branches leaves, three individuals. voucher material was deposited at Herbarium EFC. morphology described key prepared. 29 species, belonging 11 genera, documented: Blepharocalyx (1), Campomanesia (3), Eugenia (5), Myrceugenia Myrcia (8), Myrcianthes Myrciaria Myrrhinium Pimenta Plinia (1) Psidium (2). main characteristics used were: rhytidome aspect, appearance colour internal venation, punctuations, indumentum dimensions leaf blade. Differentiation possible using characters, greater difficulty two very similar Campomanesia.
