Taxonomic and cytogenetic analysis of species of the Anthurium (Araceae) genus native to the Brazilian atlantic forest.

The taxonomical description of native species is of utmost importance in terms of biodiversity survey and for checking the maintenance conditions of ecosystems. The fact that many species have ornamental features add value to their study because they will consist of important materials for production and trade, helping to reduce the predatory collection and to foster sustainable development. On the other hand, studies on mitotic and meiotic chromosomes – be they through conventional techniques, banding techniques or through techniques of molecular cytogenetics – and also studies on the pollinic morphology through optic or electron microscopy will be of great help for the taxonomical delimitation of genera which, very often, are poorly defined and comprehended.
