Over ten new genera are recorded for the first time, including Amentotaxus Pilger (Taxaceae), Hydrobryopsis Engler (Podostemaceae), Cyrtosia Blume and Biermannia King & Pantling (Orchidaceae), Eleutharrhena Forman and Haematocarpus Miers (Menispermaceae), Craigia W.W.

Evans (Malvaceae), Amblyanthopsis Mez (Primulaceae), Huodendron Rehder and Rehderodendron Hu (Styracaceae), Platea Blume (Metteniusaceae), Achyrospermum Blume (Lamiaceae), Christisonia Gardner (Orobanchaceae). In addition, five new species are described and illustrated:Tupistra natmataungensis Y.H. Tan & H.B. Ding, Biermannia burmanica Y.H. Tan & Bin Yang, Impatiens megacalyx Y.H. Tan & H.B.
