(Caryophyllaceae), a species described from Sicily and occurring in the central western region of the Mediterranean basin, are discussed. The names C. aggregatum Durieu ex Brign., C. densiflorum Guss., and C. siculum are lectotypified here. The taxonomic independence of C. siculum from C. semidecandrum L. and the other taxa of Cerastium L. sect. Orthodon Ser. subsect. Fugacia Fenzl is confirmed, as well as the synonymy of C. aggregatum and C. densiflorum. Key words: Cerastium siculum, Fugacia, lectotype, taxonomy, morphological characters 1. Introduction Cerastium siculum Guss. (Caryophyllaceae) is an annual species belonging to Cerastium L. subgen. Cerastium sect. Orthodon Ser. subsect. Fugacia Fenzl (Pax and Hoffmann, 1934). This species was described by Giovanni Gussone in 1832 from several coastal localities in SE Sicily. It is reported from central western Mediterranean areas such as Algeria, Corsica, France, the Balearic Islands, Italy, Libya, Morocco, Sardinia, Sicily, and Spain (Marhold, 2011). However, its occurrence in Spain and the Balearic Islands has been reported in error, and in Sardinia it is questionable (Arrigoni, 1984; Valdés, 1984). A detailed report of its occurrence in France was proposed by Croze et al. (2016) and Traclet et al. (2016). A .
