A study on the vegetation related to streams and rivers of the Nevadense sector of Sierra Nevada (Southern Spain) has been carried out by detennining its main structural, floristic, ecological, chorologic and dynamic characteristics. A total of nine new syntaxa have been highlighted: four associations (Caricetum camposii-cuprinae, Ranunculo granatensis-Cochlearietum megalospermae, Cirsio micranthi-Scripetum holoschoeni, Carici camposii-Salicetum atrocinereae), two subassociations (Myrrhoidi-Alliarietum petiolatae nepetosum granatensis, Carici camposii-Salicetum atrocinereae, Salicetosum capreae), two variants (Rubo-Rosetum corymbiferae variant with Adenocarpus decorticans, Rubo-Coriarietum myrtifoliae variant with Adenocarpus decorlicans) and one community (Cratoneuron commutatum and Anagallis tenella community).
