Resumo
O g\ênero Crenea \é composto por duas esp\écies, Crenea maritima e C. patentinervis, restrito \às costas e estu\ários do norte da Am\érica do Sul da Col\ômbia ao Par\á, no Brasil. Estudos taxon\ômicos tratando exclusivamente de Crenea s\ão restritos. Este trabalho teve por objetivo divulgar a ocorr\ência de Crenea maritima para o Delta do Rio Parna\íba (Piau\í e Maranh\ão), assim como caracterizar sua morfologia, taxonomia e condi\ç\ões ecol\ógicas. As ilustra\ç\ões foram baseadas nos principais caracteres diagn\ósticos das amostras coletadas.

Abstract
The genus Crenea consists of two species, Crenea maritima and C. patentinervis, restricted to the coasts and estuaries of northern South America from Colombia to Par\á in Brazil. Taxonomic studies dealing exclusively Crenea are few. This study reports a new record for Crenea maritima in the Delta of the Rio Parna\íba (Piau\í and Maranh\ão states, Brazil), as well as characterizing the morphology, taxonomy and ecology of this species. The illustrations was based on the main diagnostic characters of the species as observed in the collected samples.

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.

Leaf characters of populations of the aquatic macrophyte Montrichardia linifera were studied using geometric morphometrics to compare variation with traditional circumscriptions of the two recognized species. Two hundred and ten individuals were sampled from seven populations in the delta region of the Rio Parna\íba, north-east Brazil. Six landmarks of the leaf blade were digitized from images and analysed with MorphoJ software. Procrustesaligned configurations were studied using principal component analysis and canonical variates analysis in the pooled data and individual populations. Sinus shape variation was studied using landmark configurations of the posterior lobe basiscopic lamina. Covariation of leaf blade shape, basiscopic lamina shape, secondary vein number and petiole ligule length was investigated with partial least squares analysis. Allometry of these variables with leaf blade centroid size was investigated using multivariate regression, linear modelling and analysis of covariance. Measured variables varied continuously over the ranges previously reported for the two species. The characters of the two species morphotypes covaried and were only partly influenced by allometric effects. Symmetric shape variables predominated, but a distinctive left- and right-handed asymmetry occurred in all populations. Genetic and ecological studies are needed to investigate the significant inter-population differences further. The study offers a methodology for a broader combined morphometric/molecular investigation
