“…In several other genera, such as Begonia , Impatiens , Zingiber , Calanthe , Strobilanthes , Hoya , and Agapetes ( Fig. 5 ), recent taxonomic studies have contributed to progress on the flora of Myanmar ( Wood and Scotland, 2009 ; Tong and Xia, 2014 ; Kurzweil and Ormerod, 2018 , 2019 ; Ruchisansakun et al, 2018 ; Aung and Tanaka, 2019 ; Hughes et al., 2019 ; Maw et al, 2020 ; Rodda et al., 2019 ; Yang et al, 2019 ) and increased our understanding of the diversity of these genera in Myanmar. However, although temperate components (e.g., Rhododendron and Primula ) and some tropical dominant genera (e.g., Ficus , Ixora , Syzygium , and Diospyros ) in Myanmar are highly diverse, our knowledge of these components is relatively limited ( Kress et al, 2003 ; Table S3 ).…”

These publications include morphological descriptions and specimen locations, and form the basis for future large-scale syntheses, and for conservation risk assessment and strategy development (e.g., Khine and Schneider, 2020 ).…”

Contributions to the flora of Myanmar from 2000 to 2019

et al. 2020

Myanmar is botanically rich and floristically diverse: one of the world's biodiversity hotspots. However, Myanmar is still very unevenly explored, and until a plant checklist was published in 2003, relatively little work was done on its flora. This checklist included 11,800 species of spermatophytes in 273 families. Since this checklist was published, the botanical exploration of Myanmar has accelerated and there have been many additional publications. We therefore surveyed the literature of taxonomic contributions to Myanmar’s vascular flora over the last 20 years (2000–2019) and compiled a list of new and newly described taxa. Our list includes 13 genera, 193 species, 7 subspecies, 19 varieties, and 2 forms new to science; and 3 families, 34 genera, 347 species, 4 subspecies, 7 varieties, and 1 form newly recorded in Myanmar. Altogether, they represent 91 families and 320 genera. Most of the new discoveries belong to 15 families, with more than 25% (146 taxa) belonging to Orchidaceae. These new discoveries are unevenly distributed in the country, with about 41% of the newly discovered species described from Kachin State in northeast Myanmar. This reflects the incompleteness of our current knowledge of the flora of Myanmar and the urgent need for a greatly expanded effort. The completion of the flora of Myanmar requires more fieldwork from north to south, taxonomic studies on new and existing collections, and some mechanism that both coordinates the efforts of various international institutions and initiatives and encourages continued international cooperation. In addition, producing modern taxonomic treatments of the flora of Myanmar requires the participation of experts on all vascular plant families and genera. There is also an urgent need to attract young scientists to plant taxonomy, to work on inventories, identification, nomenclature, herbarium work, and comparative studies.

“…Based on further comparison with all the previously published species in Begonia sect. Sphenanthera ( Smith et al 1986 ; Ku et al 1997; Pham1999 ; Huang and Shui 2006 ; Hughes 2008 ; Averyanov and Nguyen 2012 ), its two-petalled female flower and the serpentinous adaxial leaf surface are distinct and unique in this section.…”

Begonia kingdon-wardii Tebbitt was rediscovered in 2014 from Myanmar after 67 years based on its last collection in 1937. Its previously unknown female flower and inaccurate morphology of leaf and ovary have been additionally described. This species belongs to Begonia sect. Sphenanthera (Hassk.) Warb. due to its dioecious habit, 3-locular ovary, berry fruits and thick placenta segments. Morphologically, it is similar to Begonia gulinqingensis S. H. Huang & Y. M. Shui in the leaf shape, placentation and fruit shape, but different in its dioecious plants, pliciform leaves, two-petalled female flowers and berry fruits. The rediscovery of this amazing living species will attract significant interest for scientific research and horticultural application.

“…Twenty‐eight new species of tree ferns were published in 2019, mainly Alsophila from New Guinea and Cyathea from Venezuela and Colombia. Forty‐five new species of Begonia were also published (BOX 3), mainly from SE Asia, including the remarkable B. rheophytica (Figure 2d), which grows in fast‐flowing water (Hughes, Aung, & Armstrong, 2019).…”
