The study showed the presence of several vegetation classes: Potametea, Bidentetea, Isoeto-Nanojuncetea, Phragmito-Magnocaricetea and Molinio-Arrhenatheretea. Some of the observed phytocenoses result very interesting because they are quite rare in Italy, as Myriophyllo verticillati-Nupharetum lutei or Epipactido palustris-Schoenetum nigricantis; furthermore a new association it has been described: Cirsio palustris-Eupatorietum cannabini. Then a phytocenosis of Molinia arundinacea has been analysed bearing two variants, one with Schoenus nigricans and one with Cladium mariscus. As some of these areas are subjected to severe environmental stress, some methods for their conservation and protection are suggested. 2005-01-01T00:00:00Z http://hdl.handle.net/10366/56386 2005-01-01T00:00:00Z http://hdl.handle.net/10366/56390 2005-01-01T00:00:00Z http://hdl.handle.net/10366/56392 Presentamos un nuevo capítulo dentro de la serie de contribuciones al conocimiento actualizado de la Flora de Galicia, aportando información de interés corológico sobre 11 taxa recolectados: Bidens frondosa L., Crypsis alopecuroides (Piller & Mitterp.) Schrad., Cyperus fuscus L., Cyperus michelianus (L.) Link, Dittrichia graveolens (L.) Desf., Echinochloa crus-galli (L.) P. Beauv. subsp. hispidula (Retz.) Honda, Eragrostis curvula (Schrad.) Nees, Hypericum hirsutum L., Lindernia dubia (L.) Pennell, Polygonum x lenticulare Hy y Xanthium echinatum Murray subsp. italicum (Moretti) O. de Bolòs & J. Vigo. En total suponen 4 primeras citas regionales y 5 primeras citas provinciales; como caso excepcional se incluye una cita por ser la primera muestra, recolectada a nivel regional, desde hace más de 50 años. Al menos 8 de ellos se encontraron en diversos hábitats de orillas fluviales catalogables dentro de las clases fitosociológicas Bidentetea tripartitae e Isoeto- Nanojuncetea. Es destacable que casi la mitad de las especies del total se corresponden con especies alóctonas.; All along the line dealing with knowledge of Galician flora, notices about 11 chorologically interesting taxa are presented: Bidens frondosa L., Crypsis alopecuroides (Piller & Mitterp.) Schrad., Cyperus fuscus L., Cyperus michelianus (L.) Link, Dittrichia graveolens (L.) Desf., Echinochloa crus-galli (L.) P. Beauv. subsp. hispidula (Retz.) Honda, Eragrostis curvula (Schrad.) Nees, Hypericum hirsutum L., Lindernia dubia (L.) Pennell, Polygonum x lenticulare Hy and Xanthium echinatum Murray subsp. italicum (Moretti) O. de Bolòs & J. Vigo. It means 4 first records at regional level and 5 first records at provincial level; as an exceptional case, another taxon is presented as the first regional record in the last half century. At least 8 of them were recorded at riverine habitats included in Bidentetea tripartitae and Isoeto-Nanojuncetea phytosociological classes. It is relevant to underline that near half of species number of this collective are alien plants. 2005-01-01T00:00:00Z http://hdl.handle.net/10366/56391 Se realiza un estudio monográfico de Vitis vinifera L. subsp. vinifera, que comprende: la descripción botánica de la especie, el hábitat y el cultivo; la recolección y la conservación de la droga; el estudio y descripción de las características morfológicas y anatómico-microscópicas de los órganos oficinales, que permiten identificar la droga en trociscos.
