Bulliform cells in Loudetiopsis chrysothrix (Nees) Conert and Tristachya leiostachya Nees (Poaceae): structure in relation to function
(Brazilian Archives of Biology and Technology, 2008-02-01) [Artigo]
Este trabalho relata as características anatômicas e ultra-estruturais das células buliformes em Loudetiopsis chrysothrix (Nees) Conert e Tristachya leiostachya Nees. Ambas as espécies apresentam enrolamento foliar em ...
Two novel reports of semidry stigmatic surface in Asteraceae
(Flora, 2011-01-01) [Artigo]
Research documents related to the morphology and function of style branches and stigmatic surface of Asteraceae are still rather few, and the literature reports are thus controversial. We report in the present study that ...
Estruturas secretoras de mucilagem em Hibiscus pernambucensis Arruda (Malvaceae): distribuição, caracterização morfoanatômica e histoquímica
(Acta Botanica Brasilica, 2011-12-01) [Artigo]
No presente trabalho foram estudadas as estruturas secretoras de mucilagem de Hibiscus pernambucensis aos microscópios de luz e de varredura. Conhecida como guaxima-do-mangue e algodão-do-brejo, é espécie nativa encontrada ...
Evaluation of different protocols for anatomical studies in Parmeliaceae (lichenized Ascomycota)
(Micron, 2009-02-01) [Artigo]
Anatomical information on most lichen species, including Parmeliaceae species, is scarce and superficial. This is partially due to the technical difficulties found during the preparation of samples and sections suitable ...
Cellular markers indicative of ozone stress on bioindicator plants growing in a tropical environment
(Ecological Indicators, 2016-08-01) [Artigo]
Ozone (0(3)) is an oxidative pollutant that causes visible foliar symptoms in sensitive plants. Importantly, cellular markers induced by physiological alterations, including oxidative burst (OB), hypersensitive response-like ...

Este trabalho descreve o nectário extrafloral (NEF) de Hibiscus pernambucensis, uma espécie nativa encontrada ao longo do litoral brasileiro, vegetando áreas de manguezal e restinga. NEFs ocorrem como sulcos profundos com ...
Thallus structure and isidium development in two Parmeliaceae species (lichenized Ascomycota)
(Micron, 2009-07-01) [Artigo]
(Thallus structure and isidium development in two Parmeliaceae species (lichenized Ascomycota)). Conventional techniques for structural studies under light microscope and scanning electron microscope were employed to ...
A New Species of Eriosema (Leguminosae, Papilionoideae, Phaseoleae) from Mato Grosso do Sul, Brazil, with a Secretory Structure Novel to the Genus
(Phytotaxa, 2016-06-01) [Artigo]
Eriosema grearii, a new species for the genus (Leguminosae, Papilionoideae, Phaseoleae, Cajaninae), is described and illustrated. Similar to E. heterophyllum, it differs from it morphologically by the free (vs. joined) ...
