Flora of Espírito Santo, Brazil: Alismataceae

Abstract

This floristic survey of Alismataceae from the state of Espírito Santo aims to update the diversity and extinction vulnerability data for the species. The taxa here listed were obtained from Splink and Reflora Virtual Herbarium databases. A total of seven native taxa were registered for Espírito Santo state: Echinodorus grandiflorus, E. macrophyllus, Helanthium bolivianus, Hydrocleis nymphoides, Limnocharis flava, Sagittaria lancifolia and S. rhombifolia; the exotic species Alisma plantago-aquatica presented one single record. The populations occurred in flooded areas located at low altitudes and were primarily collected from some preserved areas and in the coastal region of the state. This study presents a taxonomic identification key, morphological descriptions and species illustrations. Comments on ecology, conservation and geographical distribution of the species are also presented.
