Previous studies reported Psidium as one of the most difficult genera to delimit within the American Myrtaceae. Even though palynology has improved the taxonomy of Angiosperms, information about the usefulness of pollen morphology for taxonomic purposes in Myrtaceae remains contradictory. Here, we investigate the significance of pollen morphology f...

Molecular DNA markers are used for detection of polymorphisms in individuals. As they are independent of developmental stage of the plant and environmental influences, they can be useful tools in taxonomy. The alleles of simple sequence repeat (SSR) markers (or microsatellites) are traditionally used to identify taxonomic units. This application de...
