Abstract：
Gupo Mountain is adjacent to the Nanling Biodiversity Conservation Priority Area of China, which nurtures rich biological resources. To understand the diversity of macrofungal species in this area, a survey and collection of macrofungal resources in Guangxi Gupo Mountain Provincial Nature Reserve (abbreviate as Gupo Mountain) and adjacent areas was conducted by random tracking method, and combined morphological and molecular biological methods to identify. The results were as follows: (1) A total of 348 species macrofungal were found in this area, belonging to 175 genera in 69 families in 2 phyla, 6 orders and 17 classes, including 40 species of edible mushrooms, 42 species of medicinal mushrooms and 7 species of toxic mushrooms. (2) The analysis of the species composition of the region shows that the dominant families were nine families, including Agaricaceae, Boletaceae, Entolomataceae and Hymenochaetaceae, etc.; the dominant genera are eleven genera, including Amanita, Crepidotus, Crinipellis, Entoloma, etc. (3) There are two endemic genera in China, namely Fragiliporia and Zangia, and 11 endemic species, namely Coltricia crassa, Coltricia weii, Entoloma caespitosum, Entoloma praegracile, Entoloma subtenuicystidiatum, Fomitiporia tenuitubus, Fomitiporia torreyae, Fragiliporia fragilis, Perenniporia nanlingensis, Perenniporia subtephropora and Tremella cerebriformis. (4) Analysis of the funga composition of macrofungi in Gupo Mountain and adjacent areas revealed that the composition of families can be divided into cosmopolitan element (66.67%), pantropic element (17.39%) and north temperate element (15.94%); while the genera can be divided into seven elements, among which the cosmopolitan element is the most dominant (61.71%), and pantropic element (20.57%) and north temperate element (13.71%) rank second and thirdly. The rich species data provide basic information for the assessment of macrofungal species diversity and sustainable utilization of resources in Gupo Mountain and adjacent areas.

Abstract： Carex as a super large genus with high species diversity in the world, 100 species of Carex have been recorded from Guangxi at present. The resources of Carex in Guangxi are still unclear, the in-depth investigations and researches are lack too. Based on specimens identification, literature research and field investigation, we systematically cleared up the early researches of Carex in Guangxi, in order to provide background data for the subsequent research and sustainable utilization. At first, the research brief histories of Carex taxonomy in Guangxi were summarized. The genus Carex in Guangxi with high endemism, we focus on 16 taxa of Carex published based on types collected from Guangxi, verify the accuracy of their type locality, supplement distribution information, and make sure that 8 species of Carex endemic to Guangxi at last. Eight newly recorded species of Carex in Guangxi are reported here, which are C. alopecuroides D. Don, C. chungii Z. P. Wang, C. hirtiutriculata L. K. Dai, C. insignis Boott, C. nubigena D. Don, C. sendaica Franch., C. sociata Boott and C. transversa Boott. The morphological feature diagnosis and voucher specimens for these newly recorded species were provided.

Abstract： Type specimens are not only the basis and evidence of plant classification, but also important basic data for the protection and sustainable utilization of plant resources. In order to promote the full utilization and reciprocal sharing of type specimens in IBK, the species, collecting locality, collecting date and collector of them were counted and analysed respectively. The results were as follows：(1) Based on the digital information of 4 645 collections and 5 736 herbarium type specimens in IBK, there are 2 128 species of vascular plants among them, which belong to 619 genera and 170 familes (include subspecies, varieties and forms), the dominant families in the collection of type specimens include Lauraceae, Gesneriaceae, Rubiaceae, Theaceae, Orchidaceae, Urticaceae, Liliaceae, Actinidiaceae, Euphorbiaceae, Ebenaceae, Ericaceae, etc. the dominant genera include Begonia, Aspidistra, Aristolochia, Ardisia, Ilex etc; (2) The type specimens were collected from 20 provinces, autonomous regions, municipalities and special administrative regions of China and 2 other countries. More type specimens were collected from Guangxi (48.19%), Hainan (24.14%) and Guangdong (11.63%); (3) The type specimen collection reached the peak in the 1930s and 1950s, and the peak of type specimen naming was in the 1980s, which was related to the rise of plant taxonomy in China and the compilation and research of flora of China, the average shelf life for type specimens was 21 years, and the longest shelf time is 82 years. The collection and digitization of type specimens are also discussed and prospected..

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.

Abstract：中国南方一些少数民族地区民间“端午药市”流传至今，体现了民族医药的独具特色及其深远影响。为了解瑶族端午药市交易现状和发掘民族医药传统知识，采用民族植物学等方法对湖南省蓝山县端午药市进行调查，完成包括基原、地方名、药用部位、用途和用法、出现频度等内容的药用植物编目。结果表明：蓝山县端午药市药用植物种类丰富，收集并鉴定了共计103 科222 属262 种，药用植物种类广泛分布于各科和属中，其中种类较多的科有五加科（11 种）、茜草科（11 种）、菊科（11 种）、百合科（10 种）、唇形科（9 种）、蝶形花科（8 种）、芸香科（7 种）。药市药浴植物畅销且种类多样，达94 种，占总数35.9%，体现瑶族在治疗疾病上以预防保健为主的理念。经统计药市上均未被国家药典和地方标准收录的药用植物有131 种，占总数50.2%，成为发掘新药源、新用途的潜在资源。该研究还对端午药市售药者年龄进行调查，发现售药者的年龄主要集中在50～59 岁间，占总人数67%，40 岁以下的仅占总人数3%，可见民族药用传统知识的传承存在传承人老龄化、潜在传承人数量锐减的现象。该文还对药市交易药用植物的种类组成和民族药用特色进行了分析，探讨了端午药市对药用传统知识保护与传承的影响，并对蓝山端午药市的可持续发展提出了建议。

Abstract： Begonia L. is belonged to the family Begoniaceae within Cucurbitales. The genus contains about 2 000 species and is the fifth largest angiosperm genus. The species occur in subtropical and tropical regions of Asia, Northern American and Africa and have been used as important medicinal, edible or ornamental plant. In China, there are around 200 species in the genus of Begonia, which mainly occurs along south of the Yangtze River, especially in Yunnan and Guangxi. During recent decades, more and more taxa have been discovered and described owing to deep field surveys within Guangxi. Now the number is far exceed the record in Flora of Guangxi that was published in 1991 including 19 species. However, these new taxa are scattered in different journals, it is necessary to collect and gather them together. Therefore, based on examination of specimens and literature, 84 taxa were enumerated, including 2 subspecies, 11 varieties and 46 endemic species. Meanwhile, all taxa were supplemented with the diagnostic characters as well as the infrageneric classification of these taxa. This research will provide essential information on further studies about classification, evolution and conservation in Begonia.
