Betula megrelica, the Megrelian birch, is a very rare species of flowering plant in the family Betulaceae.[1][2] It is native to western Georgia, and has only been found in two locations, Mt. Migaria and Mt. Jvari, in the Egrisi Range of the Caucasus Mountains.[1][3] A shrub or small tree reaching 4 m (13 ft), it is typically found in thickets at elevations from 1,200 to 2,000 m (3,900 to 6,600 ft).[1][2][3] A dodecaploid, it is in a clade with the decaploid B. medwediewii (Caucasian birch) and the diploid B. lenta (cherry birch, native to eastern North America).[4] In spite of its rarity and endangered status, it is available from specialty nurseries.[2]
