Abstract:—The genus Vriesea Lindl. Vriesea section in the state of Paraná: taxonomic and molecular aspects. Vriesea Lindl is the most differentiated genus in the Bromeliacea, with a total of 207 species reported for Brazil being the genus with thelargest specific diversity found in the Atlantic Forest. It is estimated that 38 species of the Vriesea occur in southern Brazil, and of these 34 are found in Parana State, 23 of which fall under the Vriesea section. In the recent publicationof the Vascular Plant List of Paraná were cited 27 Vriesea species. The aim of this study is to know the diversity of the genus Vriesea section Vriesea found in the State of Paraná, emphasizing the morphological and taxonomic aspects andconservation status of the taxa. This work is part of a master?s thesis in progress. Field trips to localities and other sitesin different areas, ecosystems and altitudinal levels in the State of Paraná were carried out to collect specimens of thetaxa for the study. These localities include the phytogeografic domains: Cerrado, Atlantic Forest, Araucaria forest andgrasslands. The collected material was herborized according to plant taxonomy methodology and the specimens weredeposited in the Herbarium HUPG. Morphological analyses and geographical distributions were based on herbariumspecimens from the following herbaria: HUPG and MBM. To identify the material we studied original descriptions,photos and herbarium specimens. The conservation status for each species was evaluated using the World Conservation Union (IUCN) criteria, and was based on the herbarium material and field observations. Given the difficultyin identifying some species, molecular analysis will be conducted to support the identification of these species. As apartial result, 11 species belonging to the genus Vriesea section Vriesea, ten of which were collected in Atlantic forest areas (V. carinata Wawra , V. ensiformis (Vell.) Beer, V. erythrodactylon E. Morren, V. flava A. Costa, H. Luther& Wand., V. inflata (Wawra) Wawra, V. incurvata Gaud., V. heterostachys (Baker) L. B. Sm., V. phillipocoburgiiWawra, V. procera (Mart. ex Schult. & Schult. f.) Wittm. and V. rodigasiana E. Morren) and five species in areasof Araucaria forest (V. friburguensis, V. procera, V. phillipocoburgii and V. rodigasiana ). The most representativespecies of the Atlantic forest areas were: V. phillipocoburgii, V. ensiformis, V. incurvata, V. procera and V. rodigasiana,which were observed in different environments of this phytogeografic domain. Species such as V. rodigasiana and V. procera were more frequently observed in the coastal areas of the state while V. carinata, V. erythrodactylon, V. flava, V. heterostachys and V. inflata have only been found so far in the Serra da Graciosa. We elaborated morphological
descriptions, identification keys, geographical distribution maps and illustrations of the studied taxa.
