Numerous works were carried out on wetland vascular plants from Morocco, but it not obvious to come up with a comprehensive synthesis or an update of the data. To highlight the current state of knowledge on wetland facultative vascular plants from Morocco, a synthesis of previous related works was carried out. Thus, an inventory of 338 plant taxa, belonging to 220 genera and 72 botanical families, has been established. The endemic taxa are represented by 65 species and subspecies. In addition, 58 species and subspecies are included in the IUCN red list. The geographical distribution and, where appropriate, the auto-ecological data have also been reported for each taxon inventoried. Key words: Wetland, Flora, Diversity, Distribution, Conservation, Morocco. Introduction Wetlands are areas where drylands come into con- tact with water or are water-saturated and are char- acterized by the presence of water-dependent plant and animal species (Shine and de Klemm, 1999). The total value of wetlands depends on their eco- logical characteristics and socio-economic environ- ment (Woodward and Wui, 2001; De Groot et al., 2007). The ecological functions of wetlands include re- tention and recycling of mineral salts and macro-nu- trients (Ennabili et al., 1998, 2000; Turner et al., 2000; Trepel and Palmeri, 2002; Ennabili and Radoux, 2006), improving water quality (Dorioz and Ferhi 1994; Ezzahri et al., 2001, 2010; Libiad et al., 2012; Libiad, 2013; Ennabili et al. , 2019; Ennabili and Radoux, 2020), groundwater recharge and water lib- eration (Turner et al., 2000; in De Groot et al., 2007; SECEE, 2009), habitat for aquatic and avifauna spe- cies, plant and animal biomass production, flood control, sediment stabilization (Ennabili and Ater, 2005; Ennabili et al., 1998, 2000; in Woodward and Wui, 2001; SECEE, 2009), retention of toxic sub- stances, and maintenance of biodiversity (Turner et al., 2000; Libiad, 2013; Libiad et al. , 2012, 2015). Plants of wetlands can also be used for wetlands conservation and management and, in turn, indi- rectly improve their physico-chemical characteris- tics (Cronk and Fennessy, 2001; Ennabili and
