The Cerrado is the second largest Brazilian morphoclimatic domain. It very rich in species, many endemic but it is also influenced by surrounding phytogeographic domains. The Cerrado, particularly cerrado woodland, is vulnerable to changes in climate and soil and to wildfires. Based on the avaliation of the richness of the herbaceous of the cerrado woodland of an urban RPPN want to answer the following questions: What is the growth habit, biological form and dispersal syndrome predominant? These species are exclusive of Cerrado phytogeographical domain? Samples were collected from May 2007 to June 2008 in a remnant of cerrado woodland on the RPPN/UFMS, Campo Grande, MS. We found 59 species, 49 genera and 17 families. The families most representative were Fabaceae (15 species), Poaceae (12) and Asteraceae (seven). Predominated the erect herbs (83%), hemicryptophyte (59%) and autochorich (61%). About distribution of species in Brazilian phytogeographic domains, 12% are exclusive to Cerrado and 16% are in Cerrado, Amazônia, Caatinga, Mata Atlântica and Pampa.
