The authors present here a list of 32 mosses belonging to 15 families: Brachytheciaceae, Cryphaeaceae, Entodontaceae, Hedwigiaceae, Hypnaceae, Leptodontaceae, Meteoriaceae, Neckeraceae, Pilotrichaceae, Polytrichaceae, Pterobryaceae, Racopilaceae, Rigodiaceae, Stereophyllaceae, and Trachypodaceae, all collected in the mountainous forests of the Yungas of the NW of the Argentina (Jujuy, Salta, Catamarca and Tucumán provinces), and also in the rainforests from the NE of the country (Misiones province). Eight species: Atrichum polycarpum, Chrysohypnum elegantulum, Pilosium chlorophyllum, Pilotrichella flexilis, Porotrichodendron lindigii, Pseudotrachypus martinicensis, Steerecleus scariosus, and Thamnobryum fasciculatum are new records for the bryologic flora from Argentina. Braunia imberbis and Squamidium brasiliense are two new records for the bryophytic flora of the Catamarca province; Porotrichodendron superbum is new for the Salta province, while Forsstroemia coronata is the first record for the Catamarca and Jujuy provinces. Aerolindigia capillacea, Braunia reflexifolia, Chryso-hypnum diminutivum, Meteorium deppei and Meteoridium remotifolium are five new citations for the Jujuy province, and Schoenobryum concavifolium is new for the bryophytic flora of the Misiones province. Many studied species occur more frequently in the Yungas than in the NE rainforests; others show separated distribution but live in both areas, the Yungas and Paranaense area, and others are more or less restricted to the Paranaense rainforest of the NE of Argentina. The taxonomy of species is updated, and comments are included on bibliographical precedents, ecology and chorology of each taxon.

Se estudia la fenología de la floración de 56 especies de angiospermas en un área mediterránea del noroeste ibérico. Esta presenta una fuerte concentración de la floración en el mes de Mayo y un predominio de períodos de floración cortos (1=4.6 semanas). Su comparación con un área Eurosiberiana próxima pone de manifiesto los fuertes contrastes existentes como respuesta a la heterogeneidad ambiental de ambas áreas.

Although considerable effort has gone into the study of the subject, the Early Bronze Age of northwestern Iberia remains one of the more poorly understood phenomena of the Iberian Bronze Age. Most past attempts to systemise the relevant archaeological evidence did suffer from certain conceptual problems, particulary Harrison’s notion of a ‘Montelavar horizon’ or ‘Montelavar group’, formulated thirty years ago. As a consequence, neither this nor any of the other concepts which have been put forward in the past, has ever been embraced by a majority of scholars. In the present article, we are trying to solve at least some of the problems that plagued earlier concepts, by taking a fresh look at the Early Bronze Age funerary record from northwestern Iberia. At the same time, we are looking at the role played by Galicia and northern Portugal in the network of interregional contacts which characterize the Early Bronze Age in Western Europe.
