Abstract： Primulina pingguoensis H.S. Ma & B. Pan, a new species of Gesneriaceae from Guangxi Zhuang Autonomous Region, China, is illustrated and described here. The new species morphologically resembles Primulina carinata Y.G. Wei, F. Wen & H.Z. Lü, but it differs from the latter by lobes narrowly lanceolate-linear，length-width ratio >2 (rounded-ovate，length-width ratio <1.5), 8–10 purple stripes from corolla throat to the bottom of corolla tube, without honey guides (vs. brown stripes, 2 yellow honey guides inside, leaf blade elliptic to broadly ovate, 6.5–9.5 × 4.5–6.5 cm (vs. broadly elliptic to ovate, 4.0–5.0 × 3.0–4.0 cm), leaf blade base slightly cuneate (vs. rounded), corolla tube tubular, ventrally carinate, (vs. narrowly funnelform, strongly carinate, forming a clear keel), etc. The conservation status of P. pingguoensis is considered as ‘Critically Endangered’ (CR) according to the IUCN red list categories and criteria.

Abstract： Based on literature research, specimens identification and field investigation, we systematically cleared up the early researches of Sedum and conducted an overview for the species diversity of Sedum in Guangxi. There are 17 species was confirmed, among which six species are newly recorded. At first, the research brief histories of Sedum taxonomy in Guangxi were summarized. The following is the revised information for S. polytrichoides Hemsl. Six newly recorded species of Sedum are reported here, which are S. leblancae Hamet., S. lipingense R. B. Zhang, D. Tan & R. X. Wei, S. lungtsuanense S. H. Fu, S. makinoi Maxim., S. subtile Miq., S. tosaense Makino. The morphological feature diagnosis and photographs for these newly recorded species were provided. Finally we also discussed the species diversity and the potential utilization of Sedum in Guangxi. It is hoped to provide background information for the subsequent research and utilization of this genus.

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： 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：苦苣苔科植物是个研究活跃的类群，近年来随着新类群的报道和分类系统的变动，在该科的分类学研究中出现了不少学名的种加词的性和属名不一致或出现拼写错误的情况，虽然这些错误不影响该名称的合格发表，但还是有必要根据《国际藻类、菌物和植物命名法规》进行改正。本文就苦苣苔科植物中属名以-stigma 结尾的学名、属名以-cheilos 结尾的学名、根据属名词尾不容易判断出性别的学名、拼写错误的名称等问题进行了分析讨论，并对13个不符合法规的名称予以了改正，最后还就苦苣苔科植物学名的合格发表和规范使用进行了讨论。

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：中越边境喀斯特地区是全球生物多样性热点地区，也是生物多样性保护的关键区域，近年来在该地区发现了多个蛛毛苣苔属植物的新种。微花蛛毛苣苔于2001 年在越南北部喀斯特地区首次采集到标本，直到2018 年才被发表出来，然而发表时仅基于一号花发育未成熟的标本，故该物种的诸多形态特征仍不清楚。作者开展中越边境喀斯特地区植物多样性调查时，在我国云南东南部也发现了微花蛛毛苣苔，并采集到花发育成熟的植株，对其进行了解剖观察和测量，现对该物种进行补充描述，并提供墨线图和野外生态照片以资辨认。

Abstract：广西乐业大石围天坑群是最典型的塌陷型天坑群。采用样线法和样方法对天坑群种子植物进行了实地调查，结合已有资料综合分析了大石围天坑群种子植物区系特征。结果表明：大石围天坑群野生种子植物丰富，有137科445属863种；在科级和属级水平上，地理成分以热带成分为主，中国特有成分相对贫乏；与热带区系的联系主要以泛热带成分为主，与温带区系的联系主要以北温带成分为主；热带科和温带科之比,热带属和温带属之比，大石围天坑群都小于中国乐业-凤山世界地质公园，其种子植物区系更能反映该地区过去植物组成的“原貌”，即温带成分过去较现代比例更高,是全球气候变暖的有力证据；天坑群保育了82种珍稀濒危植物，包括30属67种野生兰科植物，是现存珍稀濒危植物的“避难所”。
