Re-establishment of Sileneneglecta Ten. (Caryophyllaceae) with taxonomic notes on some related taxa.

Sileneneglecta has been misunderstood and confused with S.nocturna , although several morphological characters (petal shape, calyx indumentum, hairiness of stamen filaments, seed size, seed-coat surface and shape) allow separation of these species. Moreover, S.mutabilis (which has been considered conspecific with S.neglecta ) and S.martinolii (an alleged endemic species to south-western Sardinia) are considered here as taxonomic synonyms of S.nocturna and S.neglecta , respectively. These taxonomic conclusions are strongly supported by multivariate morphometric analyses of 21 characters.
