Schischkin (in Komarov, Fl. URSS 6: 626. 1936) stated that the type of Silene tenuis, a name very often applied to plants in this group, “does not correspond to the Siberian plant [ S. graminifolia Otth] and belongs to some other species.” It is imperative that the identity of S. tenuis be settled.
