The aroid flora shows greater similarity to those of central Brazil and Amazonia than to the Atlantic forest. Most species occur in humid forest fragments - the "florestas serranas".
Geophytes are also found in caatinga and dry forest Taccarum ulei and lithophytes on rock outcrops in dry forest Philodendron acutatum. Floating aquatics occur in ponds and lakes throughout the state Pistia stratiotes, Lemna aequinoctialis, Lemna minuta, Spirodela intermedia, Wolffia columbiana, Wolffiella welwitschii , and freshwater helophytes Montrichardia linifera along river margins. An identification key and data on geographic distribution and conservation status are provided.
