Results of floristic and phenological research carried out between 1983 and 1985 on the beach around the mouth of the river Liscia (North-eastern Sardinia) are reported.
304 species, belonging to 208 genera and 63 families, including a considerable number of species of phytogeographic interest,were found.
Data about the anthesic rhythm of each species have been collected; considerations about the synphenology of the community and of the different types of biological forms are discussed. Relationships of synphenological rhythms, biological spectrum and climate are considered
