Addicions i comentaris a la Flora vascular autòctona i al·lòctona de les Muntanyes de Prades

Abstract

57 new records of vascular plants for the flora of the Prades Mountains (Southern Catalonia) are detailed; 30 are autochthonous and 27 allochthonous, with a wide chorological range. Anacyclus homogamus is formally cited for the first time for Catalonia. The discovery of Orobanche castellana near Prades represents an important novelty for the Catalonian flora. Among the allochthonous species many are new for the studied area and, besides, for the south of Catalonia. For others of infrequent occurrence we increase or complete the distributional range with new UTM 10 × 10 grid squares. We augment significantly the group of non-native plants with new records. Many of these species are of recent introduction, not appearing in floristic catalogues prior to 2000 nor in more recent floristic treatments. The most probable causes and arrival routes of these introductions are ennumerated in the discussion.
