Abstract

Plant communities in the Amazon rainforest are still poorly known due to insufficient plant material collected and a lot of unidentified material in herbaria. New low-cost and very effective tools are welcome to help solving taxonomic problems associated to these difficulties. Myrcia s.l. (Myrtaceae) is a diverse taxon in the Amazon rainforest, where it is subjected to problems related to group delimitation. Therefore, we aim to test the local delimitation of all 51 species/morphospecies and infrageneric taxa (sections) of Myrcia s.l. occurring in Area of Relevant Ecological Interest Biological Dynamics of Forest Fragments Project, Amazonas State, Brazil. Quantitative and qualitative morphology and the near-infrared spectroscopy will be used to test the current circumscription of groups through Cluster Analysis and Linear Discriminant Analysis. This research is innovative in studies of the Brazilian Myrtaceae and it contributes to increase the knowledge about this family in the Amazon, where it is still insufficiently understood.
