The vascular flora of the cerrado in Emas National Park (Central Brazil): a savanna flora summarized
The Brazilian cerrado may be divided in two main phytogeographic sectors: one characterized by Piptocarpha rotundifolia, in which the Emas National Park (ENP) is located, and other characterized by Curatella americana. We carried out a floristic survey in ENP, which allowed an assessment of the taxonomic composition, taxa size, and similarity with other sites for the ENP's vascular flora. We compared the ENP's flora with southeastern outlying cerrado sites, also in the Piptocarpha sector, and with general floristic patterns in the cerrado vegetation. The distribution of species per family in ENP was significantly different from that obtained for each component of the general cerrado flora. The herbaceous component was characterized by an overproportion of Myrtaceae and an underproportion of Orchidaceae and Lythraceae; and the woody component, by an overproportion of Myrtaceae and Nyctaginaceae. When compared with outlying cerrado sites, the ENP was quite distinct, not only at species level, but also at family level.
