Specimens were collected from upper-montane spruce forests, in lake and littoral zones and serpentine foothill streams and were identified using standard regional floras; all vouchers are deposited in the Herbarium of the University of Prishtina (UPH). The discovery of L. annotinum subsp. annotinum adds a new boreal-montane element to the national Lycopodiaceae, while <i>N. marina</i> represents the first documented member of the genus <i>Najas</i> in the country.
