“…De acordo com Gil & Bove (2007), a análise morfológica do gênero Eleocharis dificulta a percepção da lâmina foliar, e a consequência disso é o relato de ausência de folhas para esse táxon. Em descrições do gênero, considera-se que a planta tenha apenas bainha.…”

RESUMO -No ecossistema aquático há uma faixa de umidade gradiente no solo que interfere diretamente na ocupação das espécies à margem da lâmina de água. Essa zonação ecológica reflete os graus de adaptação que as plantas apresentam para tolerar o alagamento ou a dessecação. O presente trabalho visou apresentar a análise morfoanatômica de cinco espécies de Cyperaceae encontradas em diferentes zonas no entorno da represa Alagados, em Ponta Grossa-PR, Brasil: Cyperus giganteus, Rhynchospora corymbosa var. aspérula, Cyperus densicaespitosus, Cyperus rigens e Eleocharis sp. Estruturas caulinares e foliares das cinco espécies de Cyperaceae foram analisadas a partir de cortes histológicos. Concluiu-se que, das cinco plantas analisadas, somente três caracterizam-se como plantas aquáticas, sendo duas classificadas como plantas emergentes e uma como submersa fixa devido às características adaptativas que apresentam para obter sucesso nesse ambiente.Palavras-chave: anatomia caulinar, anatomia foliar, aerênquima, estresse.ABSTRACT -In the aquatic ecosystem there is gradient moisture in the soil that interferes directly in the occupation of species on the margin of the water blade. This ecological zone reflects the degrees of adaptation that plants present to tolerate flooding or drying. This work aimed to present a morphological and anatomical analysis of five species of Cyperaceae, found at different zones in the surroundings of the Alagados Dam, in Ponta Grossa-PR, Brazil: Cyperus giganteus and Rhynchospora corymbosa var. asperula, Cyperus densicaespitosus, Cyperus rigens and Eleocharis sp. Stem and foliar structures of five species of Cyperaceae were analyzed by histological cross-section. It was concluded that of the five plants examined, only three are aquatic plants, with two being classified as emerging plants and one as fixed submerged, based on the adaptive characteristics they present to succeed in this environment.

A taxonomic survey of the genus Eleocharis R. Br. was carried out in the four municipalities of coastal Piauí state (Cajueiro da Praia, Ilha Grande, Luís Correia and Parnaíba) included in the Parnaíba Delta Environmental Protection Area. The survey was based on the morphological study of newly collected and existing herbarium material. Six species, native but not endemic to Brazil, were recorded: Eleocharis elegans (Kunth) Roem. & Schult., E. filiculmis Kunth, E. flavescens (Poir.) Urb., E. geniculata (L.) Roem. & Schult., E. mutata (L.) Roem. & Schult. and E. subarticulata (Nees) Boeckeler. Eleocharis flavescens and E. subarticulata are new records for Piauí and E. subarticulata also for the Brazilian Northeast. Descriptions, illustrations, identification keys and information on geographic distribution and habitat are presented. The identification key is provided in English and Portuguese.

-(Cyperaceae in the Apodi-Mossoró River, Rio Grande do Norte State, Brazil). The Apodi-Mossoró River, located in the Caatinga biome, has its course characterized by diverse landscape sand humid environments, as well as by many members of the family Cyperaceae. Studies on the flora of Cyperaceae are scarce in northeastern Brazil and nonexistent for Rio Grande do Norte State. Twenty-one botanical expeditions were undertaken in this area during the period from July 2007 to May 2008 on four main points in the municipalities of Felipe Guerra, Governador Dix-Sept Rosado, Luís Gomes, and Mossoró. Seven genera and twenty-five species of Cyperaceae were found in the Apodi-Mossoró River, twenty-one of which are new records for Rio Grande do Norte State.This figure more than doubled the number of species of the family known to occur in this Brazilian State. Botanical descriptions, taxonomic comments, identification keys, and illustrations are provided.
