      We examined here the diversity and distribution of Vitaceae species in Ceará state, Brazil, as part of the "Flora of Ceará Project: knowing to conserve", analyzing the morphological characters of specimens collected in the field, those available in the ALCB, BHCB, EAC, CEN, EAFM, HCDAL, HST, HUEFS, HUVA, HVASF, IAN, IPA, K, MBM, MOSS, NY, P, R, UEC, and US herbaria or in the specialized literature. We include here an identification key, occurrence maps, morphological descriptions, and comments concerning their ecology. The main morphological features for species delimiting were leaf type and symmetry, trichome and tendril types, presence or absence of streaks on branches, stipule, flower bud and fruit shape. Eleven species of Vitaceae included within two genera were recorded in Ceará: Cissus albida, C. blanchetiana, C. campestris, C. erosa, C. gongylodes, C. subrhomboidea, C. sulcicaulis, C. tinctoria, C. verticillata, C. xerophila, and Clematicissus simsiana. The species were registered in 45 municipalities, with C. erosa and C. verticillata being widely distributed. Those species inhabit different phytoecological areas in Ceará, although preferentially growing in Stepic Savanna (Caatinga). Six species occur in nine legally protected conservation areas. Ceará state holds 40.74% of the registered species of the family found in northeastern Brazil. [ABSTRACT FROM AUTHOR]

      Examinamos aqui a diversidade e distribuição de espécies de Vitaceae no estado do Ceará, Brasil, como parte do projeto "Flora do Ceará: conhecer para conservar", analisando caracteres morfológicos de amostras obtidas em campo, em coleções depositadas em herbários (ALCB, BHCB, EAC, CEN, EAFM, HCDAL, HST, HUEFS, HUVA, HVASF, IAN, IPA, K, MBM, MOSS, NY, P, R, UEC, US) ou publicadas em literaturas especializadas. Chave de identificação, descrições morfológicas, comentários sobre a ecologia e mapas de ocorrência dos táxons foram incluídos. Os principais caracteres para o reconhecimento das espécies foram o tipo e simetria das folhas, tipos de tricomas e gavinhas, presença ou ausência de estrias nos ramos e formas da estípula, botão floral e fruto. No território cearense ocorrem 11 espécies de Vitaceae pertencentes a dois gêneros: Cissus albida, C. blanchetiana, C. campestris, C. erosa, C. gongylodes, C. subrhomboidea, C. sulcicaulis, C. tinctoria, C. verticillata, C. xerophila e Clematicissus simsiana. As espécies foram registradas em 45 municípios, sendo C. erosa e C. verticillata as que apresentaram distribuição mais ampla. As espécies habitam diferentes unidades fitoecológicas no Ceará, no entanto, crescem preferencialmente na Savana Estépica (Caatinga). Seis espécies ocorrem em nove diferentes Unidades de Conservação. O estado do Ceará detém 40,74% das espécies registradas da família no nordeste brasileiro. [ABSTRACT FROM AUTHOR]
