Lectotypification of Arenaria graminifolia Ard., Arenaria rosani Ten. and Arenaria alpicola Ten. (Caryophyllaceae)

Three names based on Italian specimens relating to the Minuartia graminifolia complex are lectotypified. Arenaria graminifolia, the basionym of Minuartia graminifolia (Ard.) Jáv. subsp. graminifolia is lectotypified by an Arduino specimen at LINN, and Arenaria rosani, the basionym of M. graminifolia subsp. rosani (Ten.) Mattf. by a Tenore collection at NAP; both lectotypifications maintain current usage of these names. In addition, Arenaria alpicola Ten., now considered a synonym of Minuartia graminifolia subsp. clandestina (Portenschl.) Mattf., is also lectotypified by a Tenore collection at NAP referable to that subspecies
