Anthurium circinale (Araceae), a New Species from the Inselbergs of the Atlantic Forest of Brazil

Abstract

Here we describe Anthurium circinale Theófilo & Arantes, a new species of Anthurium Schott (Araceae) from the Sugarloaf Land region in eastern Brazil. We emphasize the importance of using unusual characteristics to define species within the genus, such as flower shape and androecium. We present illustra­tions and a distribution map. Furthermore, we high­light the need for further research focused on detailed evaluations of floral structures within Anthurium sect. Urospadix Engl.
