          Abstract

          In this study, we describe several new taxa belonging to the flora of Myanmar. One new family, Polyosmaceae ( Polyosma wallichii Benn.) is recorded. 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. Smith & W.E. 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. Ding, Amblyanthopsis burmanica Y.H. Tan & H.B. Ding, Platea kachinensis Y.H. Tan & H.B. Ding. The distribution, ecology, phenology, and conservation status of these new species are also described.

          Resolving basal lamiid phylogeny and the circumscription of Icacinaceae with a plastome-scale data set.

          Major relationships within Lamiidae, an asterid clade with ∼40000 species, have largely eluded resolution despite two decades of intensive study. The phylogenetic positions of Icacinaceae and other early-diverging lamiid clades (Garryales, Metteniusaceae, and Oncothecaceae) have been particularly problematic, hindering classification and impeding our understanding of early lamiid (and euasterid) character evolution.

              The medicinal plants of Myanmar

              Abstract A comprehensive compilation is provided of the medicinal plants of the Southeast Asian country of Myanmar (formerly Burma). This contribution, containing 123 families, 367 genera, and 472 species, was compiled from earlier treatments, monographs, books, and pamphlets, with some medicinal uses and preparations translated from Burmese to English. The entry for each species includes the Latin binomial, author(s), common Myanmar and English names, range, medicinal uses and preparations, and additional notes. Of the 472 species, 63 or 13% of them have been assessed for conservation status and are listed in the IUCN Red List of Threatened Species (IUCN 2017). Two species are listed as Extinct in the Wild, four as Threatened (two Endangered, two Vulnerable), two as Near Threatened, 48 Least Concerned, and seven Data Deficient. Botanic gardens worldwide hold 444 species (94%) within their living collections, while 28 species (6%) are not found any botanic garden. Preserving the traditional knowledge of Myanmar healers contributes to Target 13 of the Global Strategy for Plant Conservation.
