Abstract
This paper provides a floristic inventory of Angiosperms reported from Parque Estadual de Itaúnas, Espírito Santo, Brazil. The inventory was performed with fortnightly fieldwork from 2012 to 2015. The samples collected are available at the herbarium VIES. A checklist with 562 species, from 345 genera and 110 families is provided. Lifeforms categories were established: shrubs and trees; terrestrial herbs; herbaceous and woody climbers; epiphytes and hemiepiphytes; aquatic herbs, parasites (holo- and hemi-), and myco-heterotrophs (saprophytes). Fabaceae, Myrtaceae, Cyperaceae, Rubiaceae, Bromeliaceae, Apocynaceae, Orchidaceae, Poaceae, Bignoniaceae, and Melastomataceae presented the greatest species richness. The genera Eugenia (16 spp.) (Myrtaceae), Passiflora (10 spp.) (Passifloraceae), Myrcia (9 spp.) (Myrtaceae), Cyperus (7 spp.), and Chamaecrista (Fabaceae) and Miconia (Melastomataceae) (6 spp., each) presented the greatest species richness. Most of the previous checklists elaborated in the Espírito Santo state have underestimated plant species diversity. This floristic inventory confirms the ecological value of the restingas in the Atlantic Forest located at Parque Estadual de Itaúnas.
