Chaves interativas para identificação das famílias Chysobalanaceae e Sapotaceae dos município de Alvarães e Tefé

Abstract

The Amazon rainforest is made up of several groups of plant species, including the Chrysobalanaceae and Sapotaceae families, which are among the main tree families in the Amazon. Interactive keys areuseful tools for recognizing plant species, especially in rich ecosystems. However, there are still few publications for plant diversity in the municipalities of Alvarães and Tefé, AM. Therefore, the present work aimed to develop an interactive key for each one of the Chrysobalanaceae and Sapotaceae families. So, the list of species of Chrysobalanaceae and Sapotaceae from Alvarães and Tefé available on the online platform Reflora – Virtual Herbarium were listed. Each species was described morphologically through specialized bibliography, and its vegetative characteristics were used to construct interactive keys on the XPER3 platform. were listed 30 species of Chrysobalanaceae and 22 species of Sapotaceae, and the most representative genus of each family respectively was Licania and Pouteria. The characteristics most used in the keys were: limbus format, philotaxy, base and apex of the limbus, type of venation, habitus, presence of stipules, latex, glands and other aspects. For both families, the interactive key was considered easy to use.
