Abstract

This is a further contribution to the knowledge of the desmid flora of Cuba. One hundred and sixty samples collected from the most important regions in regard to occurrence of desmids and diversity of mi croalgae species in Cuba (Pinar del Río, Isla de la juventud, Ciénaga de Zapata, Matanzas and San Felipe, Camagüey), were examined. Emphasis was made on the taxonomic survey of those cylindrical" representative genera. 22 infrageneric taxa belonging to 17 species were identified, 18 of which are new records from the country. Some populations examined showed a wide morphological variability. Each taxon is briefly described based on Cuban material. Original drawings and comments about distribution and synonymy according to the available taxonomic literature are included.
