Resumo
O gênero Crenea é composto por duas espécies, Crenea maritima e C. patentinervis, restrito às costas e estuários do norte da América do Sul da Colômbia ao Pará, no Brasil. Estudos taxonômicos tratando exclusivamente de Crenea são restritos. Este trabalho teve por objetivo divulgar a ocorrência de Crenea maritima para o Delta do Rio Parnaíba (Piauí e Maranhão), assim como caracterizar sua morfologia, taxonomia e condições ecológicas. As ilustrações foram baseadas nos principais caracteres diagnósticos das amostras coletadas.

Palavras-chave: Crenea, macrófita aquática, mangue, nova ocorrência.

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 Pará in Brazil. Taxonomic studies dealing exclusively Crenea are few. This study reports a new record for Crenea maritima in the Delta of the Rio Parnaíba (Piauí and Maranhão 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.


Key words: Crenea, aquatic macrophytes, mangrove, new record.

The study consists of a taxonomic treatment of the Araceae of Ceará, 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 Ceará 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.
