Última Flower and floral trichome morphology of species of Dyckia Schult. f. (Bromeliaceae, Pitcairnioideae), and their importance to species characterization and genus taxonomy Acta Botanica Carvalho,Jordano Dorval Tavares de; Essi,Liliana; Oliveira,João Marcelo Santos de. ABSTRACT This paper presents a morphological analysis of the flower and floral trichomes of three rare species of Dyckia: Dyckia ibicuiensis, D. polyclada and D. racinae. Flowers at anthesis were collected from natural populations and subjected to morphometric and microscopic analysis. Among the most representative features for Dyckia are: morphometrics of individual floral parts; the general configuration of the androecium and gynoecium; the degree of fusion of the stigmatic lobes; the morphology of the ovules, especially in relation to the chalazal appendix; and the presence and constitution of peltate trichomes in the perianth, which exhibited a polymorphism not previously reported for Dyckia. The characters were effective at describing each species,...

(Bromeliaceae, Pitcairnioideae) species: new data for taxonomic use Acta Botanica Carvalho,Jordano Dorval Tavares de; Oliveira,João Marcelo Santos de; Freitas,Cesar Carvalho de; Martins,Meriélem Saldanha. ABSTRACT This study presents a morphoanatomical analysis of Dyckia ibicuiensis , D. polyclada and D. racinae stamens. Flowers at anthesis were desiccated and their stamens were processed using common light microscopic techniques. Morphologically, the androecium in these species is differentiated by the disposition of the stamens around the gynoecium and by general anther characteristics. Included stamens, with antesepalous filaments different from those of the antepetalous, anthers in a radial disposition, always curved, and sporangia facing the gynoecium characterize D. ibicuiensis and D. racinae . This configuration results from the filament connation, as well as special anatomical characteristics of the anthers, such as the connective with thickenings....

(Typhaceae): anatomical and ontogenetic bases for taxonomic applications Acta Botanica Carvalho,Jordano Dorval Tavares de; Mariath,Jorge Ernesto de Araujo. ABSTRACT The inflorescence of plants of the genus Typha L. consists of a polytelic system with the fertile region containing staminate flowers in the terminal portion and pistillate flowers in the basal portion. Although some useful morphological information has been provided to characterize species of the genus, various divergent typologies have arisen due to mistaken interpretations that ignore the different degrees of branching in this indeterminate system. The present study aimed to identify structural homologies by comparing the morphology and ontogeny of the synflorescences of Typha domingensis, T. latifolia and their putative hybrid, T. x provincialis, using standard micro-techniques for light and electron microscopy. Analysis revealed that the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Compound spike; Inflorescence; Panicle; Prophyll; Raceme; Synflorescence; Typha.
