Nomenclatural and taxonomic notes on Carex lazarei nom. nov. (Cyperaceae)

Carex bulgarica (Domin) Lazare 1986 is a younger homonym of C. bulgarica Velen. 1889, the latter being validly published as an alternative name along with C. digitata var. bulgarica Velen. Therefore we publish here a replacement name, Carex lazarei, for the species previously called C. bulgarica by Lazare. Carex lazarei belongs to the C. sempervirens Vill. complex and its occurrence is restricted to acidophilous habitats of the Balkan mountains. Although it is often regarded as conspecific with C. sempervirens, we are of the view that this entity needs the status of species. A type specimen is designated here as the second-step lectotype of the name C. sempervirens var. bulgarica Domin.
