Abstract： fourteen species of vascular plants are reported as new records in Guangxi. They are Rumex obtusifolius L., Impatiens polyneura K. M. Liu, Pilea sinocrassifolia C. J. Chen, Synotis fulvipes (Y. Ling) C. Jeffrey & Y. L. Chen, Primulina minor F. Wen & Y. G. Wei, Hanceola exserta Y. Z. Sun ex C. Y. Wu, Isodon longitubus (Miq.) Kud�, Keiskea australis C. Y. Wu & H. W. Li, Sciaphila ramosa Fukuy. & T. Suzuki, Eriocaulon decemflorum Maxim., Lilium concolor Salisb., Arisaema silvestrii Pamp., Bulbophyllum tipula Aver., Isachne sylvestris Ridl.. And the citation and geographical distribution of each species are also listed in this paper. The discovery of these new species in Guangxi not only provides new data for the study of floristic geography in Guangxi, but also has important practical significance for the precise implementation of full coverage protection of native plants.

Abstract： The limestone region in southwest Guangxi is defined as a priority area for biodiversity conservation and research not only at provincial but also national level. Through in-depth investigation in the two nature reserves of this region, twenty angiosperm species from 20 genera and 17 families were found as new records for the flora of Guangxi, including Wuodendron praecox (Hook. f. & Thomson) B. Xue, Y. H. Tan & X. L. Hou, Phoebe macrocarpa C. Y. Wu, Clematis fengii W. T. Wang, Trichosanthes tetragonosperma C. Y. Cheng & Yueh, Sorbus yunnanensis L. T. Lu, Elatostema longibracteatum W. T. Wang, Acer paihengii Fang, Cornus eydeana Q. Y. Xiang & Y. M. Shui, Rhododendron longipedicellatum Lei Cai & Y. P. Ma, Styrax roseus Dunn, Symplocos hookeri C. B. Clarke, Dicercoclados triplinervis C. Jeffrey & Y. L. Chen, Lysimachia pittosporoides C. Y. Wu, Lycianthes marlipoensis C. Y. Wu & S. C. Huang, Justicia multinodis Benoist, Scutellaria sichourensis C. Y. Wu & H. W. Li, Liparis bistriata C. S. P. Parish & Rchb. f., Peristylus tenuicallus Ormerod, Pinalia yunnanensis (S. C. Chen & Z. H. Tsi) S. C. Chen & J. J. Wood and Zeuxine integrilabella C. S. Leou. Among them, Wuodendron B. Xue, Y. H. Tan & Chaowasku and Dicercoclados C. Jeffrey et Y. L. Chen were new recorded genera of Guangxi. All species were annotated by morphological and distribution description, voucher specimens and pictures. In addition, based on collected materials, several key taxonomic characteristics of T. tetragonosperma and D. triplinervis were supplemented and revised respectively. Lastly, the biogeographic significance of these newly records as well as protection effectiveness of the reserves in limestone region of southwestern Guangxi were discussed.

Abstract： Based on literature, field work, collection, examination and identification of related specimens, we found a newly recorded species of Phyllanthaceae from China——Sauropus racemosus Beille. It differs from other species of Sauropus in having glabrous young branches,glabrous leaves, racemoses 3 to 5 clustered on the lower part of the old stem branchlets. In this paper, a detailed description, the photographs and geographical distribution of S. racemosus are given. In addition, we consider S. racemosus as ‘Endangered’ (EN) based on the IUCN categories and criteria. The discovery of S. racemosus enriched the diversity of plant species in the Sino-Vietnanese border area. It reflects that the Sino-Vietnanese border area are biodiversity hotspots in the world and key areas for biodiversity conservation. It also shows that the plant investigation in this area is not enough, and further investigation and research are needed.
