Abstract： Seventeen newly recorded species from Guangxi, China are reported, including Yinshania henryi (Oliv.) Y. H. Zhang, Lepidium didymum L., Rumex acetosella L., Impatiens chekiangensis Y. L. Chen, Pittosporum kweichowense Gowda, Reevesia orbicularis Tardieu, Itea ilicifolia Oliv., Eriobotrya henryi Nakai, Myrsine verruculosa (C. Chen) Pipoly & C. Chen, Mycetia hirta Hutch., Spermacoce exilis (L. O. Williams) C. D. Adams, Picris divaricata Vaniot, Mazus gracilis Hemsl. ex Forbes et Hemsl., Viburnum rhytidophyllum Hemsl., Caryopteris nepetifolia (Benth.) Maxim., Salvia nanchuanensis var. pteridifolia Sun, and Smilax elegantissima Gagnep. These newly recorded species are of great value to the study of floristic geography, the innovative utilization of plant resources and the protection of plant diversity in Guangxi. The invasiveness of Lepidium didymum L. and Spermacoce exilis (L. O. Williams) C. D. Adams, which are alien species, was evaluated. The medicinal efficacy of Yinshania henryi (Oliver) Y. H. Zhang, Lepidium didymum L., Rumex acetosella L., Picris divaricata Vaniot, Mazus gracilis Hemsl. ex Forbes et Hemsl., Schnabelia nepetifolia (Benth.) P. D. Cantino, Salvia nanchuanensis var. pteridifolia Sun, Viburnum rhytidophyllum Hemsl., Itea ilicifolia Oliv., which are new records of medicinal plants in Guangxi, was briefly summarized. The voucher specimens, geographical distribution and plant photographs are also provided for each species.

Abstract： Five newly recorded genera of vascular plants in Guangxi are reported, namely, Diodia L., Calyptocarpus Less, Syneilesis Maxim., Acroceras Stapf and Piptatherum P. Beauv, as well as Diodia virginiana L., Calyptocarpus vialis Less., Syneilesis aconitifolia (Bunge) Maxim., Acroceras tonkinense (Balansa) C. E. Hubbard ex Bor and Piptatherum kuoi S. M. Phillips & Z. L. Wu belonging to the five genera. Among them, Diodia virginiana L. and Calyptocarpus vialis Less. are naturalized species. The morphological descriptions and photos of two newly naturalized species are provided, and their invasiveness is evaluated based on wild investigation in Guangxi. As native plants, Syneilesis aconitifolia (Bunge) Maxim., Acroceras. tonkinense (Balansa) C. E. Hubbard ex Bor and Piptatherum. kuoi S. M. Phillips & Z. L. Wu are provided with the descriptions of characteristic diagnosis and photos. At last, the biogeographic significance for these newly recorded genera is discussed.

Abstract： Guangxi Mulun National Nature Reserve is located in the crisscross zone of Dian-Qian-Gui flora and south China flora, also is the heartland of the transition zone about Palaeoarctic flora and Palaeotropical flora. It plays an irreplaceable role in biodiversity conservation areas of China. In order to understand the plant species diversity in Guangxi Mulun National Nature Reserve, the composition and characteristics of vascular plant diversity was studied based on historical literatures, field investigations, specimens collection and identification, and data statistical analysis. The results were as follows: (1) this Reserve had 1 735 species of vascular plants, including 218 species of Lycophytes and Ferns, 1 517 species of seed plants, with abundant vascular plant diversity and complex floristic composition. (2) this Reserve had 486 species endemic to China, 56 species endemic to Guangxi, and 262 species endemic to karst areas, with significant plant endemism. (3) this Reserve had 68 species of national key protected wild plants, 153 species of Guangxi key protected wild plants, 4 species of extremely small population wild plants in China, 108 threatened plants, and 144 plants listed in the appendix of the Convention on International Trade in Endangered Species of wild Fauna and Flora (CITES), with relative high degree of rare and endangered plants. Based on the results, Guangxi Mulun National Nature Reserve is an important gene bank of karst plants. It has extremely important conservation value. This study also provides important basic data for construction and management of this Reserve, protection and sustainable utilization of plants, and other scientific research works.
