Dalbergia prazeri Prain was reported closely related to D. stipulacea Roxb., except for the sparse pubescence on the leaves beneath and the hirsute calyx. He also noted the pods of the two species are totally unlike without any explanation. Thereafter he reduced the name to D. oliveri Gamble ex Prain without explanation either. Critical studies revealed that it is conspecific with D. assamica Benth. Therefore, D. prazeri Prain is reduced to synonym under D. assamica Benth. There are 6 sheets of the collections of Prazer cited by Prain. The sheet in the herbarium CAL, with digital code CAL0000012326(herbarium No. 131311)is selected as lectotype of this name. Of the remaining collections 4 sheets in CAL and 1 sheet in K are selected as isolectotypes.]]> 2016/5/31 17:34:54 1, 2, NIU Miao^3,4, HUANG Dong-Hai², LI Shi-Jin^3*]]> WANG Fa-Song^{1, 2}, NIU Miao^3,4, HUANG Dong-Hai², LI Shi-Jin^3* 5true Epimedium were described based on a limited number of cultivated individuals. Due to the lack of adequate field investigation and morphological observation, we know little about the characters variation range, variation patterns and its taxonomic value. Indeed, the taxonomical descriptions of some species in Epimedium are probably open to questions. E. epsteinii(Berberidaceae), an endemic species of China, was collected in 1994 and then described, according to several cultivated individuals, in 1997. In order to investigate the distribution and to evaluate the morphological variation, 30 individuals per population were selected and used in the morphological observation, statistics and description. E. epsteinii is regarded as an endemic species, which was restricted distribution in the Tianpingshan Mountains of Hunan Province. However, through the extensive field investigation, it was found that the species also distributed in Nanling National Forest Park(Guangdong Province)and Jianshi County(Hubei Province). The new distribution was located in north and south of the Tianpingshan Mountains, respectively. The present report has significantly expanded the natural distribution range of E. epsteinii. Based on the ‘population' concept, extensive variation was observed among individuals and populations. Both the main quantitative traits, i.e. the plant height, inflorescence length, number of flowers, rhizome diameter, length and width of leaf, and color of flower were presented abundant variations. A correct species concept stems from a correct and thorough understanding of the nature of variation pattern of plants and its taxonomical value. Therefore, the populations not only are useful for taxonomical research, but also have great significance in contributing to a better understanding or interpretation of the variation pattern of the species. The new records of E. epsteinii in Guangdong and Hubei provinces will be useful for the resource utilization, and for further research on the spreading mechanism and phytogeography of genus Epimedium.]]> 2016/5/31 17:34:54 *]]> XU Yan-Qin, SHI Hui-Jun, LIU Shao-Xiong, HU Sheng-Fu^* 4true Erpodium mangiferae(Erpodiaceae)was reported as a new record species in China from Guizhou Province. Erpodiaceae belongs to Orthotrichinales, Isobryales and consists of five genera and 24 species of Erpodiaceae mosses which are known all over the world. They are mainly distributed in the tropical regions and among them, three genera and four species are currently recorded in China. Two species of Erpodium was reported as synonyms of Solmsiella biseriata(Austin)Steere. and Venturiella sinensis(Vent.)C. Müll. One Erpodiaceae specimen was discovered by Professor Xiong YX and ect. in Red River canyon of Luodian Town of Guizhou Province and finally was identified as E. mangiferae C. Muell. which was the first record in China. At the last, Erpodiaceae included four genera and five species in china. In this paper,detail morphological characteristics and the specific line description of each part of the sample were provided by microscope observation and the distribution feature of it was discussed. In the terms of the references,E. mangiferae C. Muell.was mainly located in the south,mid,north and northeast of India. From the latitude and longitude, this discovery site, Red River Canyon of Luodian Town of Guizhou Province is similar at the latitude to the most north distribution Assam of India and apart from the Assam about 10° at the longitude or about 1 400 km in the distance. This species was familiar with Erpodium glaziovii in the appearance,but compared the size of the perichaetial leaves and foliage leaves and whether they has primordial utricle or not with it, E. mangiferae C. Muell. are greatly different from Erpodium glaziovii.]]> 2016/5/31 17:34:54 1, XIONG Yuan-Xin^1*, YANG Bing¹, LI Xiao-Bing¹, ZHONG Shi-Mei¹, ZHOU Shu-Qin²]]> CAO Wei¹, XIONG Yuan-Xin^1*, YANG Bing¹, LI Xiao-Bing¹, ZHONG Shi-Mei¹, ZHOU Shu-Qin² 3true Chiloschista exuperei is reported from China for the first time.

As a new naturalized species in Northeast China, Viola arvensis Murray is distributed in Maoer Mountain, Harbin. It is a native to Northern Africa, Southwest Asia and Europe, also found in Taiwan region Drosera anglica Huds. was new in China, distributed in Changbai Mountain of Northeast China. There is another species in Northeast China, D. rotundifolia L. The main difference between these two species are that the former leaves are linear spoon shaped, style 3 and each style 3 is divided into the middle; the latter leaves nearly round, style 3, each style deeply split to base. The voucher specimens were preserved in the herbarium of NEFI. The find of the new material species enriches the plant species in the Northeast China and has a great significant meaning to study the plant species diversity.]]> 2016/5/31 17:34:54 1, ZHANG Yi-Fan¹, WANG Mei-Juan¹, ZHOU You^2*]]> ZHENG Bao-Jiang¹, ZHANG Yi-Fan¹, WANG Mei-Juan¹, ZHOU You^2* 1true
