摘要：
A new species of Primulaceae, Primula undulifolia, is described from the hilly area of Hunan province in south-central China. Its morphology and distributional range suggest that it is allied to P. kwangtungensis, both adapted to subtropical climate, having contiguous distribution and similar habitat, growing on shady and moist cliffs. Petioles, scapes and pedicels of them are densely covered with rusty multicellular hairs, but the new species can be easily distinguished by its smaller flowers and narrowly oblong leaves with undulate margins. Molecular phylogenetic analysis based on four DNA markers (ITS, matK, trnL-F and rps16) confirmed the new species as an independent lineage and constitutes a main clade together with P. kwangtungensis, P. kweichouensis, P. wangii and P. hunanensis of Primula sect. Carolinella.

摘要：
A new species of Chrysosplenium (Saxifragaceae), C. zhangjiajieense, is described and illustrated from Zhangjiajie, Hunan province in China. This new species is similar to C. macrophyllum in having broad basal leaves and compact cymes, but it differs from the latter in that the whole plant of C. zhangjiajieense is densely covered by coarse and long white villus, and the leaf adaxial surface bears thickly wart points. The new species is also similar to C. davidianum, but differs by having white flowers, only one cauline leaf, oblong sepals and the stamen is longer than sepals while C. davidianum possess yellow flower, 2-5 cauline leaves, orbicular sepals and the stamen much shorter than sepals. Base on the field investigation, this new species is accessed to be endangered according to IUCN category and criteria.

摘要：
Primulina suichuanensis X. L. Yu & J. J. Zhou, a new species of Gesneriaceae from Jiangxi, China, is described and illustrated. Morphologically, the new species is most similar to P. roseoalba, but differs by entire leaf blade margin, narrowly ovate bracts, reddish–purple or bluish–purple corolla, 3.0–3.4 cm long corolla tube, white filaments, and 3.6 cm long pistil. It flowers from September to November.

摘要：
A new species of Primulaceae, Primula hunanensis G. Hao, C. M. Hu & X. L. Yu, from Hunan, China, is described and illustrated. Based on its general morphology it clearly belongs to P. sect. Carolinella, characterized by the calyptrate capsules, but can be distinguished by its adaxially glabrous leaves which are much longer than the petioles, blade base broadly cuneate to subrounded, umbellate inflorescence, and glabrous pedicels and calyx.

摘要：
以大围山山顶杜鹃灌丛为研究对象,设置了6个15 m×15 m的样地。采用方差/均值比率法的t检验对杜鹃灌丛的空间格局进行了分析,同时采用负二项式参数、丛生指数、平均拥挤度指数、聚块性指数、扩散指数、格林指数和Cassic指数分析了群落内木本植物的聚集强度。结果表明: 14种常见木本植物(如杜鹃Rhododendron simsii、湖南白檀Symplocos hunanensis、四川冬青Ilex szechwanensis)中,有85.7%的物种表现为聚集分布格局;聚集强度随种群密度的增大而减小;非优势种群直角荚蒾(Viburnum foetidum var. rectangulatum)、水马桑(Weigela japonica var. sinica)、鹿角杜鹃(Rhododendron latoucheae)的聚集强度大于优势种群杜鹃、湖南白檀等;植物对山顶温凉湿润气候条件的适应能力,种子扩散方式、萌生能力和耐荫特性等生物学特性,以及干扰是决定杜鹃灌丛木本植物空间格局的主要驱动因子。
摘要：
报道了湖南兰科4新记录种,分别为采自汝城九龙江国家森林公园的多枝拟兰Apostasia ramifera S. C. Chen et K. Y. Lang、小毛兰Eria sinica(Lindl.)Lindl.、拟白赤箭Gastrodia albidoides Y. H. Tan & T. C. Hsu 和采自浏阳大围山的山珊瑚Galeola faberi Roife,其中拟兰属为湖南省新记录属。凭证标本保存于中南林业科技大学植物标本室(CSFI)。湖南省新发现的4种兰科植物,分布区域跨度均较大,在兰科植物区系研究上,有较大价值。兰科植物是森林中的精华,种类虽多,但很多种居群极小,对生态环境要求高,基本上都生长于未受干扰的原生林下或石壁上,因此兰科植物的生境保护显得尤为重要,对湖南兰科植物的调查和保护进行了探讨。
