Populations of Unonopsis guatterioides (Annonaceae) in Amazonas and Minas Gerais, Brazil, potentially represent different species: Floral scent, flower characters and pollinators revisited

A population of Unonopsis guatteriodes (Annonaceae) in Amazonia differs from another population in Minas Gerais by flower morphology, pollination biology and floral scent emissions. In view of the differences, we encourage more in-depth studies to reveal whether the synonymous U. lindmanii R.E. Fries should be re-established as a valid taxon for the Minas Gerais plants.
