Endemism and subendemism of the early spring flora of the north-eastern part of the Lesser Caucasus were studied. In total, early spring flora of the north-eastern part of the Lesser Caucasus is represented by five species of endemics (Tulipa schmidtii, Allium szovitsii, Neotorularia eldarica, Viola caucasica and Primula woronowii) belonging to five genera and five families, and ten species of subendemics (Gagea alexeenkoana, Tulipa eichleri, Lilium ledebourii, Ornithogalum sintenisii, Scilla caucasica, Muscari caucasicum, Iris grossheimii, Iris demetrii and Iris caucasica) belonging to ten genera and four families. These endemic and subendemic species were characterised according to the study area, occurrence, life forms and geographical elements.
