Only few surveys were carried out on woody and ground layer floras of the Brazilian Cerrado. The objective of this survey was to investigate richness, floristic patterns and biological spectra of different phytophysiognomies on both strata at Santa Bárbara Ecological Station (EESB). EESB is located in the Municipality of Águas de Santa Bárbara, São Paulo State, Brazil (22º 46' 30'' to 22º 50' 30''S and 49º 10' 30'' to 49º15'30'' W, 600 to 680m high). A total of 14 angiospermic species were found, 285 of these in Cerrado sensu lato physiognomies. The richest families in species number were Asteraceae, Fabaceae, Myrtaceae and Poaceae. Asteraceae, Fabaceae and Poaceae were the richest families similar to other Cerrado's sites. The EESB biological spectra have patterns similar to other Cerrados, but with one change: chamaephytes were richer than hemycryptophytes in the open savannic physiognomies of EESB. Fire protection may be the reason of this alteration.
