'''''Betula buggsii''''' is a species of broadleaved tree that grows in the Qinling–Daba Mountains in China.<ref>{{Cite journal|last1=Wang|first1=Luwei|last2=Ding|first2=Junyi|last3=Borrell|first3=James S|last4=Cheek|first4=Martin|last5=McAllister|first5=Hugh A|last6=Wang|first6=Feifei|last7=Liu|first7=Lu|last8=Zhang|first8=Huayu|last9=Zhang|first9=Qiufeng|last10=Wang|first10=Yiming|last11=Wang|first11=Nian|date=2022-01-08|title=Molecular and morphological analyses clarify species delimitation in section Costatae and reveal Betula buggsii sp. nov.

The species was discovered by Dr Nian Wang of Shandong Agricultural University in 2021, as he sampled Chinese birch trees for a population genetic analysis. Initially he considered the trees to be ''Betula utilis'' ssp. ''albosinensis'' but genetic analysis showed the trees to be very different, and in fact, less closely related to ''Betula utilis'' ssp. ''albosinensis'' than several other birch species. In addition, the trees were diploid, whereas ''B. utilis'' ssp. ''utilis'' and ''B. utilis'' ssp. ''albosinensis'' are tetraploid. Closer analysis of the morphology of the trees also showed important differences with ''Betula utilis'' ssp. ''albosinensis.'' Nian Wang therefore described a new species, naming it ''B. buggsii'' after his former PhD supervisor, Richard Buggs.
