Limestone outcrops are considered insular biomes for plants that need richer soils mainly in areas such as Central Brazil, in which poor soils are clearly predominant. Because of this peculiar situation, plants restricted to these areas are clearly threatened by limestone mining. In Central-western Brazil, at least 6 aroid genera (  Anthuriu   m ,  Asteros tigma , Philodendron,     Spathicarpa, Taccarum and Xanthosoma) and 18 species can be found growing in limestone outcrops and are here briefly described and illustrated.
