In information regarding the "Bioma Cerrado" becomes more urgent due to its accelerated destruction. This work conducted a floristic inventory and an analysis of phytosociological parameters in an area of cerrado "stricto sensu" at Santa Cecília's farm, in São Paulo State (20º46'12"S e 47º14'24"W, 836m of altitude and Neosoil Quartzarenic). Thirty plots of 10 x 10 m were established in which 511 arborous individuals with GBH >15cm were registered and belong to 30 families and 53 species. The families with the highest numbers of species were: Fabaceae (7 species), Myrtaceae (5), Vochysiaceae (4), Annonaceae (3) and Caesalpiniaceae (3), and these represented about 45% of total species. The species with the highest importance value (IV) were: Qualea grandiflora (62,38), Dalbergia miscolobium (22,24), Styrax camporum (21,86), Ocotea corymbosa (18,02), Qualea parviflora (14,97) and Qualea multiflora (11,46). Density was 1.703 ind/ha, Diversity Shannon's index of (H') 3,05 and Similarity Jaccard's index (ISj) was 45% when compared to a close cerrado area.
