El catàleg florístic dels Països Catalans. Addicions i modificacions introduïdes en la tercera edició de la Flora manual dels Països Catalans

Abstract

Here we discuss the main changes recorded in the third edition of «Flora manual dels Països Catalans» in comparison with the first edition, which came out fifteen years ago. As well as numerous small changes to the data for the species (distribution, ecology), a number of new taxa have been added to the Flora: 23 genera, 152 species and 163 subspecies or microspecies. These new taxa correspond in the main to plants already known from neighbouring territories, but others have been described as new taxa during the last fifteen years, such as a number of new microspecies of Limonium or Alchemilla. A third group includes 29 allien species that have become naturalised in recent years, most of which arrived from the Americas or from tropical areas. On the other hand, 49 taxa have been excluded, since the corresponding data have been found deficient or erroneous.
