Resumo: There is a discrepancy in literature about the identification of species from Desmanthus genus. The aim was to characterize anatomically three genotypes representing Desmanthus pernambucanus (7G, 50J) and D. virgatus (13AU) species. The material was collected in experimental field of the Academic Unit of Serra Talhada (UAST/UFRPE) in dry season. Leaves of different ages were collected and fractionated into petiole, extrafloral nectary, rachis, petiolule and leaflet, following the slide preparation. Petiole morphology varied among genotypes and leaves studied. Extrafloral nectary is calyx-shaped whereas petiolule showed similar morphology in all genotypes. Rachis had similar morphology in 7G and 50J, for both leaves showing upper projections containing vascular bundles, whereas 13AU genotype showed a cylindrical shape. The leaflet showed a single layer of epidermal cells and dorsiventral mesophyll, except in young leaflets of 7G and 50J genotypes. It was observed secretory cavities in phloem at all fractions, except in the leaflets. There are anatomical and morphological features that may be useful to distinguish the studied species.

El objetivo fue caracterizar anatómicamente tres genotipos que representan las especies Desmanthus pernambucanus (7G, 50J) y D. virgatus (13AU). El material fue recolectado en el campo experimental de la Unidad Académica Serra Talhada (UAST / UFRPE), en la época seca. Se recolectaron hojas de diferentes edades y se dividieron en pecíolo, nectario extrafloral, raquis, pecíolo y folíolo, seguido de preparación de la hoja. La morfología del pecíolo varió entre genotipos y hojas. El nectario extrafloral mostró forma de cáliz mientras que el peciolulo tenía forma de U en todos los genotipos estudiados. En el raquis, la morfología de 7G y 50J fue similar, en ambas hojas con proyecciones superiores, mientras que el genotipo 13AU presentó forma cilíndrica. El foliolo presentaba una sola capa de células epidérmicas y mesófilo dorsiventral, a excepción de las hojas jóvenes de genotipo 7G y 50J. Se observaron cavidades secretoras en el tejido del floema en todas las fracciones estudiadas, excepto en los folíolos. Los cristales prismáticos se presentaron en todos los genotipos y fracciones estudiadas. Existen características anatómicas y morfológicas que permiten la distinción entre las especies estudiadas.Existem discrepâncias na literatura quanto a identificação de espécies do gênero Desmanthus. Objetivou-se caracterizar anatomicamente três genótipos que representam as espécies Desmanthus pernambucanus (7G, 50J) e D. virgatus (13AU). O material foi coletado no campo experimental da Unidade Acadêmica de Serra Talhada (UAST/UFRPE), na estação seca. Folhas de diferentes idades foram coletadas e fracionadas em pecíolo, nectário extrafloral, ráquis, peciólulo e foliólulo, seguindo-se o preparo das lâminas. A morfologia do pecíolo variou entre genótipos e folhas. O nectário extrafloral apresentou formato de cálice enquanto o peciólulo apresentou-se em aspecto de U em todos os genótipos estudados. Na ráquis, a morfologia do 7G e 50J foi semelhante, em ambas as folhas com projeções superiores, enquanto o genótipo 13AU apresentou formato cilíndrico. O foliólulo apresentou-se com uma única camada de células epidérmicas e mesofilo dorsiventral, exceto nas folhas jovens do genótipo 7G e 50J. Foram observadas cavidades secretoras no tecido floemático em todas as frações estudadas, com exceção dos foliólulos. Ocorreram cristais prismáticos em todos os genótipos e frações estudadas. Existem características anatômicas e morfológicas que permitem a distinção entre as espécies estudadas.Research, Society and Development2021-12-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2377610.33448/rsd-v10i16.23776Research, Society and Development; Vol. 10 No. 16; e418101623776Research, Society and Development; Vol. 10 Núm. 16; e418101623776Research, Society and Development; v. 10 n. 16; e4181016237762525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/23776/21094Copyright (c) 2021 Hactus Souto Cavalcanti; Marcos Cícero Pereira dos Santos; Gêsica Samíramys Mayra da Silva Brito; Vicente Imbroisi Teixeira; Clébio Ferreira Pereira; Alberício Pereira Andrade; Divan Soares da Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCavalcanti, Hactus Souto Santos, Marcos Cícero Pereira dos Brito, Gêsica Samíramys Mayra da Silva Teixeira, Vicente Imbroisi Pereira, Clébio Ferreira Andrade, Alberício Pereira Silva, Divan Soares da 2021-12-20T11:03:07Zoai:ojs.pkp.sfu.ca:article/23776Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:42:32.300748Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
