The relationship of Betula kenaica to other white-barked birches is not well understood, although it and the following species are evidently closely allied to B. papyrifera, from which they have likely been derived. Betula kenaica differs from B. papyrifera primarily in its smaller stature and in its smaller, blunter-tipped, more coarsely and regularly serrate leaves.
Betula ×hornei Butler (= Betula kenaica W. H. Evans × B. nana Linnaeus), variously intermediate between its parents, is common throughout the range of B. kenaica (which is mostly overlapped by that of B. nana).
