Here we present a survey of Orchidaceae from Vitória da Conquista, Brazil and an analysis of the floristic similarity among ten areas in Bahia and Minas Gerais. Fourty-four species of orchids were found in the municipality. Among the species found, two are new occurrences for the Northeast region of Brazil, Acianthera panduripetala and Specklinia hymenantha, and one is a new occurrence for the state of Bahia, Pabstiella seriata. Analyzes were conducted using the UPGMA algorithm, Jaccard and Dice coefficient and Correspondence Analysis. The cluster analysis revealed low similarity rates, except for Serra Negra + Ibitipoca State Park. Two groups were formed: one group of dry forest areas and another group encompassing the Rupestrian Fields and Ombrophilous Forest areas of the two states. The results suggest that the areas of the same phytophysiognomy are more related to each other than to the vegetation of the same state.
