Abstract: (Floristic and structure of woody vegetation of a "cerrado rupestre" area in Serra de Caldas Novas State Park, Goiás): The cerrado stricto sensu is the predominant phytophisiognomy of the Cerrado biome, covering large areas of the Brazilian Central Plateau. When the vegetation grows on rocky soils, it is known locally as "cerrado rupestre". Our knowledge of the tree-shrub communities of this Cerrado vegetation subtype is very limited. The aim of this study was to analyze the floristic composition and structure of tree-shrub vegetation in an area of cerrado rupestre located in the Serra de Caldas Novas State Park (PESCAN), Goiás, Brazil, and to compare the floristic and structural characteristics with those from other areas of cerrado stricto sensu located in Central Brazil. We sampled all individuals with a diameter ≥ 5 cm at 30 cm above ground level, presented in 10 randomly plots of 20 × 50 m. The floristic richness survey revealed 66 species, distributed in 53 genera and 31 botanical families. The studied vegetation had floristic and structural characteristics similar to those recorded in other areas of cerrado stricto sensu growing on deep soils, however, there were some species typically of cerrado rupestre, such as Schwartzia adamantium (Cambess.) Gir.-Cañas and Wunderlichia mirabilis Riedel ex Baker and other less abundant characteristic species for this biome, for instance, Peltogyne confertiflora (Mart. ex Hayne) Benth., Myrcia canescens O. Berg and Myrcia variabilis DC. The total basal area was relatively high (12.39 m2.ha-1) due to the high density of individuals (1.357 ind.ha-1) as well as the abundance of large individuals of species such as Sclerolobium paniculatum Vogel, Pterodon pubescens (Benth.) Benth., S. adamantium and P. confertiflora. Hence, the flat soil surface of cerrado rupestre of PESCAN did not limit the growth of wood vegetation, nor conditioned the establishment of a distinguished flora. Nevertheless, the elevated structural importance of few wood species typical and adapted of rock environments guarantee some floristic peculiarity of the community survey.
