长轴钩轴莎及其近缘种在系统分类学上的位置

Also on Taxonomic Status of Uncinia Microglochin(Wahlenb.)Clarke and its Relatives

作者认为在Ｃａｒｉｃｅａｅ分类系统中居重要地位的所谓长轴苔草（ＣａｒｅｘｍｉｃｒｏｇｌｏｃｈｉｎＷａｈｌｅｎｂ．）或长轴嵩草（Ｋｏｂｒｅｓｉａｍｉｃｒｏｇｌｏｃｈｉｎ（Ｗａｈｌｅｎｂ．）Ｊ．ＴａｎｇｅｔＦ．Ｚ．ＷａｎｇｅｘＹ．Ｃ．Ｙａｎｇ）事实上是一个Ｕｎｓｉｎｉａ的衍生种类。从比较形态解剖学、植物地理及生态学各方面的证据表明，Ｕ．ｍｉｃｒｏｇｌｏｃｈｉｎ及其近缘的ＣａｒｅｘｐａｒｖａＮｅｅｓ．和ＣａｒｅｘｐａｕｃｉｆｌｏｒａＬｉｇｈｔｆ．应属于Ｕｎｃｉｎｉａ。除此之外．作者分析讨论了有关Ｃａｒｉｃｅａｅ的各主要分类系统并指出：只有将ｃａｒｉｃｅａｅ中争议性最大的Ｕ．ｍｉｃｒｏｇｌｏｃｈｉｎ及其亲缘种归入Ｕａｃｉｎｉａ，才可能圆满地解决Ｕ．ｍｉｃｒｏｇｌｏｃｈｉｎ特殊的结构形态所带来的系统学问题，才可能最好地适应现有的有关Ｃａｒｉｃｅａｅ分类和系统演化的假说。并对其作以下处理：Ｕ．ｍｉｃｒｏｇｌｏｃｈｉｎ（Ｗａｈｌｅｎｂ．）Ｃ．Ｂ．ＣｌａｒｋｅＵ．ｐａｒｖａ（Ｎｅｅｓ．）Ｅ．ＮｅｌｍｅｓｅｘＤ．Ｓ．ＤｅｎｇＵ．Ｐａｕｃｉｆｌｏｒａ（Ｌｉｇｈｔｆ．）Ｅ．ＮｅｌｍｅｓｅｘＤ．Ｓ．

In this paper the author considers the socalled Carex microglochin wahlenb, or Kobresiamicroglochin(Wahlenb.)J.Tang et F.Z.Wang ex Y.C.Yang and its relatives which occupya important status of classification in Cariceae are Uncinai actually.Due to envidences fromcomparative morphology,anatomy,ecology and pytogeogrphy, it should be put into Unciniaobviously. The main Hypotheses of Phylogeny in Cariceae are discussed. In addition,the auhtor point out that it is the best treatment and the most satisfactory conclusion which supported by diverse evidence.and the treatment about U. microglochin and its relatives is givenblow:Uncinia microglochin (Wahlenb.)C.
