About some allocthonus species in the upper Segre basin (Northeastern Iberian Peninsula), new or very rare for the Catalan flora
Article Sidebar
Main Article Content
We provide recent data about six allocthonous flora species in the upper basin of Segre river (Pyrenees, Catalonia, NE Iberian Peninsula). We report for the first time populations of Silene noctiflora in the Iberian Peninsula and Vitis riparia as a invasive species in Catalonia. We also note that Heracleum mantegazzianum expands its regional area along the Segre river from an initial focus on the uppermost basin.
