麻栗坡兜兰——兜兰属与杓兰属的一个中间类型，兼论兜兰属的地理起源问题

Paphiopedilum malipoense S. C. Chen et Tsi is a very interesting new species with its flower similar to that of Cypripedium, especially section Cypripedium.  It belongs to subgenus Brachypetalum, the most primitive group of Paphiopedilum, but differs from its allied species in hgniva elliptic-lanceolate sepal with cuspidately acuminate apex, rather narrow petals and horizontal lip, which are of common occurrence in many cypripediums, but very rare in paphiopedilums.  Apparently, this is an intermediate form, or a link, between Paphiopedilum and Cypripedium, but it does not seem to arise from hybridization between them, because no Cypripedium has been found wherever Paphiopedilum occurs.       The new species is distributed in southeastern Yunnan of China. In this area, as well as in river valleys of western Yunnan or the Hengduan Mountains, there have been four species of the same genus reported before. As we know, the Hengduan Mountains and their adjacent areas are rich in Cypripedium.  The differentiation of the genus there is remarka- ble.  All five sections it contains occur there and three of them are quite distinctive.  For example, the general appearance of the section Bracleosa is dissimilar to that of any other cypripediums, but closely resembles that of Listera.  It appears that the difference between sect.  Bracteosa of Cypripedium and sect.  Brachypetalum of Paphiopedilum is not neces- sarily wider than that between sect. Bracteosa and sect. Cypripedium of the same genus. Apparently, it is reasonable to consider Paphiopedilum to be an evolutional branch of Cy- pripedium extending into tropical area, with its primitive group (subgenus Brachypetalum) still remaining in its northern fringe area.  This primitive subgenus has eight species, dis- tributed from western Yunnan to the Malay Peninsula.  Five of them, including the inter- mediate and primitive form published here, are found in the hilly land of southeastern Yun- nan and the river valleys of western Yunnan.  All these facts suggest its area of origin: the river valleys of the Hengduan Mountains and the lower hilly land contiguous to the southof them.     

云南鳞毛蕨属泡鳞亚属的分类研究

本文修订了鳞毛蕨属泡鳞亚属的特征范围，对该亚属的2个组12个种进行了分类研 究，发现其中有新种1个，云南新分布的种5个。本文还对长期混淆不清的Dryopteris labo-rdei与D．gymnosora 的分类特征还进行了清理，恢复前者为独立存在的种。     

栎属青冈亚属（壳斗科）的叶表皮研究

利用光镜和扫描电镜观察了栎属青冈亚属Quercus subgen. Cyclobalanopsis 48种植物的叶表皮，尤以对叶下表皮的毛被特征观察较为仔细。共观察到8种不同类型的叶表皮毛：单列毛、单毛、乳突、星状毛、溶和星状毛、具柄束毛、多出毛和水母状毛。其中乳突在青冈亚属中较常见，而在壳斗科其他属中仅在石栎属 Lithocarpus 少数种类中有报道；水母状毛首次在壳斗科中发现。毛被可能遵循以下的演化规律：乳突→单毛→星状毛；星状毛依照从简单→复杂的演化途径，分化出各种形态各异和结构复杂的毛系。初步讨论了毛被以及叶表皮其他特征(如毛基细胞和表皮细胞的形态、气孔的类型和密度等)的分类和系统学意义。     

基于ISI Web of Science的《中国地理科学》（英文版）文献计量研究

《中国地理科学》（英文版）是我国创办最早的综合性英文地理期刊,分析其发文被引用情况可以了解该刊十几年来变化情况,又可以为刊物今后的发展方向提供依据。本文利用Web of Science的引文检索功能,统计了该刊2002-2012年的被引用情况,从载文量、篇均被引频次、单篇被引频次、被引频次年代分布、被引论文专业分布和引文类型分布等几个方面,基于地理学学科特点和文献计量学方法进行综合分析,总结该刊目前发展存在的问题及改进措施,以期为刊物发展提供参考,更好地促进地理学科的发展。
