摘要

弗洛雷斯，j.r.;s.a. Catalano & g.m.

Flores;Santiago a . Catalano & Guillermo M. Suárez在形态学特征的基础上，首次对胸膜藓科苔藓(苔藓科)进行了全面的系统发育分析。数据集由73个字符组成:10个连续字符和63个离散字符。分类群取样涉及隐科9属46种，其中隐科32种。外群取样包括胸膜藓类13科21属23种。系统发育分析采用简约性作为最优准则，遵循隐含加权方法。由于该结果排除了杉树属，因此不支持杉树科的单系性。其余属组成的支系(A支系)由短刚毛(0.26 ~ 0.30 mm)组成，costa遍布最内层的包皮苞片、圆锥形的被盖和干燥条件下的贴伏叶。进一步分析发现隐科属为副属，而树隐科属为多系属。隐科包括Schoenobryum concavifolium, cytodontopsis leveillei和Dendrocryphaea lamyana，从而与其他种类的Dendrocryphaea分离。特征映射显示，由于关键物种的意外放置，诊断应该得到相当大的修改。

期刊介绍： Darwiniana is a half-yearly botanic publication of the Darwinion Botanic Institute, National Counseling of Scientific and Technical Researches (CONICET) - National Acadamey of Exact, Physical and Natural Sciences. Its mission is to publish original scientific papers and reviews from different areas of the botanical issue with the exception of those which nature are agronomical and applied botanical research (of direct transfer). Main articles are usually included in the following sections: Structure and Development; Reproductive Biology; Ecology and Phytogeography; Etnobotany; Genetics; Systematics and Taxonomy of Vascular Plants; Systematics and Taxonomy of non Vascular Plants.
