The Genus Sagina (Caryophyllaceae) in Italy: Nomenclatural Remarks.

A contribution to the nomenclature of the genus Sagina is presented. The following 10 taxa are recognized as being part of the Italian flora: S. alexandrae , S. apetala , S. glabra , S. maritima , S. micropetala , S. nodosa , S. pilifera , S. procumbens , S. revelierei , and S. saginoides subsp. saginoides . The names S. apetala var. decumbens (= S. apetala subsp. apetala ), S. bryoides (= S. procumbens ), S. patula (= S. apetala subsp. apetala ), S. revelierei , Spergula glabra (= S. glabra ), Spergula pilifera (= S. pilifera ), and Spergella subulata var. macrocarpa (= S. saginoides subsp. saginoides ) are here typified. Specimens deposited at B-W, C, E, and LY, and illustrations by Reichenbach were considered for the typifications. Specifically, two Reichenbach's illustrations are chosen for S. bryoides and S. saginoides var. macrocarpa . A specimen at B-W is designated as the lectotype of S. glabra . Two specimens at C and G are designated as the lectotypes of S. apetala var. decumbens and S. revelierei , respectively. A specimen at LY is designated for S. patula . As we did not find original material, a neotype at G is designated for S. pilifera .
