The study consists of a taxonomic treatment of the Araceae of Cear\á, a state lying within Brazil\’s semi-arid region. 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. 28 taxa (species and varieties) in 19 genera are described and most are illustrated: Anthurium (three spp.), Caladium (one sp.), Dieffenbachia (one sp.), Dracontium (one sp.), Lemna (two spp.), Monstera (two spp., one with two varieties), Montrichardia (one sp.), Philodendron (four spp.), Pistia (one sp.), Scaphispatha (one sp.), Spathicarpa (one sp.), Spathiphyllum (one sp.), Spirodela (one sp.), Syngonium (one sp.), Taccarum (one sp.), Wolffia (one sp.), Wolffiella (one sp.), Xanthosoma (two spp.), Zomicarpa (one sp.). New records for Cear\á are Dieffenbachia aglaonematifolia, Dracontium nivosum, Monstera adansonii var. laniata, Philodendron sp. aff. ruthianum and the naturalized exotic Typhonium roxburghii. An identification key and data on geographic distribution and conservation status are provided.

The genus Dracontioides was formerly considered monotypic with the only known species (D. desciscens (Schott) Eng!.) restricted to extreme eastern Brazil, growing as a helophytic herb. A second species for the genus (D. salvianii E.G. Gonc. ) is here described, also from eastern Brazil (Bahia state). It is a psammophytic herb and a neotenic origin for this species is suggested. Since the last complete description of D. desciscens is the one included in the description of the genus, both species were described, illustrated and compared. Relationship of Dracontioides with genera considered closely related as Dracontium and Anaphyllopsis is discussed, as well as biogeographic and evolutionary trends within the genus Dracontioides and closely related genera.
