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.

Anthurium trinerve Miq. var. obtusum Engl, and Spathiphyllum wendlandii Schott subsp. montanum R.A. Baker are elevated to species rank as A. obtusum (Engl.) Grayum and S. montanum (R.A. Baker) Grayum, respectively. Monstera dilacerata (K. Koch \& Sello) K. Koch, a well-known name (though never consistently applied to any particular species), is here relegated to synonymy under Epipremnum pinnatum (L.) Engl. Monstera pirmatipartita Schott, the oldest name attributable to any species previously known as M. dilacerata, is neotypified accordingly.

A taxonomic revision is presented of the three taxa of Monstera (Araceae) recognized for Bahia State, Brazil:\– M. adansonii subsp. blanchetii (stat. nov.), M. adansonii subsp. klotzschiana (stat. nov.) and M. praetermissa; a fourth taxon, not so far recorded from the state, M. adansonii subsp. laniata (stat. nov.), is distinguished from subsp. blanchetii. The two highly variable subspecies of Monstera adansonii were further investigated by morphometric study of herbarium specimens. These two taxa were distinguished using principal coordinates analysis (classical multidimensional scaling) and linear discriminant analysis; the most important diagnostic characters are stigma length and width, stigmatophore length, style apex size and leaf perforation number. Discrimination on leaf characters alone was over 90\% successful \– subsp. blanchetii differs most significantly from subsp. klotzschiana in higher values for perforation number and leaf base angle. Descriptions, illustrations, geographical and conservation status information and a key to the taxa are provided. Two neotypes are proposed (M. maximilianii Engl., M. klotzschiana Schott) and discussions of the typifications are provided.

Summary. A comparative study of the leaf outline morphometrics of Monstera adansonii var. klotzschiana, M. adansonii var. laniata and M. praetermissa was carried out. The study focused on populations in isolated montane humid (brejo) forests of Cear\á state in Northeast Brazil and compared them with populations from Amazonia and the Brazilian Atlantic Forest. Digitised outlines were prepared from a total of 1,695 field-collected leaf images from 20 populations, and elliptic Fourier analysis was used to generate matrices of coefficients, from which six shape variables (principal components) were extracted using Principal Components Analysis. Intra-population variability and inter-population differences were analysed with multivariate distance methods. Separate analyses were carried out for each of three leaf size classes (juvenile, submature, mature) because of the strong heteroblasty typical of this genus. Juvenile leaves were the least variable size class within populations of M. adansonii var. klotzschiana. The shape variables expressed very similar types of variation in all three size classes. The Cear\á brejo populations of M. adansonii var. klotzschiana showed significant differences between mature leaf outlines in all pairwise comparisons; the Pacatuba population was the most distinct. The Cear\á populations did not cluster together exclusively. In all three size classes, populations clustered together into their taxonomic groups, most clearly so in mature leaves. No correlation between morphological and geographic distance matrices was found, nor between morphological and molecular distance. The study showed that leaf outline shape is a practicable and useful quantitative trait for studying morphological variability at species, varietal and population levels.
