    Abstract

    Between the end of October and early November of 2023, we conducted a two-week-long survey of wild begonias in northern Vietnam, and found about 25 new taxa, in which, six new species are described and reported below with illustrations. They are B. bacsonensis D.K.Tian, T.S.Hoang & B.Chen, B. maciejewskii D.K.Tian, T.S.Hoang & W.G.Wang, B. sui T.S.Hoang, D.K.Tian & B.Chen, B. thanxaensis D.K.Tian, T.S.Hoang & W.G.Wang, and B. vonhaiensis T.S.Hoang, D.K.Tian & W.G.Wang, which belong to Begonia sect. Coelocentrum, and B. pyramidata D.K.Tian T.S.Hoang, W.G.Wang & B.Chen belonging to B. sect. Platycentrum. The new species are compared with their allied species and their conservation status is assigned to the Data Deficient Category on the IUCN Red List.
