Betula megrelica is a rare species from the Caucasus, where it is known only on Mount Migaria and Mount Jvari in north-western Georgia. It is closely related to Betula medwediewii, from the same region, but it has been shown that it is decaploid rather than dodecaploid. It is a small, spreading, multi-stemmed shrub, with brown young shoots ageing to grey, and the leaves are quite large, about 5 x 3 cm.

Extremely rare shrub birch from two mountains in the Caucasus.
