河南太行山蕨类植物区系的研究

初步探讨了河南太行山蕨类植物区系的特点。该区系有蕨类植物 1 0 4种 ,隶属于 2 3科 4 8属 ,优势成分以蹄盖蕨科、鳞毛蕨科等系统演化上比较高级的类群为主。组成本区系的成分来源不同 ,以温带成分占优势 ,与河北、山西、北京地区的蕨类区系关系密切 ,与山东、秦岭、长白山、黄山、鼎湖山的相似程度渐低。这与中国现代蕨类植物地理分布规律相吻合

A study on the pteridophytic flora of Mountain Taihang, Henan province

The floristic phytogeographical features of the ferns and fern allies in Mt. Taihang of Henan province are discussed. The results are as follows: The pteridophytic flora comprises 104 species,48 genera and 23 families. The dominant groups are Athyriaceae,Dryopteridaceae etc. The elements of the flora come from different floras and show obvious temperate characteristics. The flora is much more closely allied to Hebei province,Shanxi province and Beijing region than to the others of regions. It supports Ching Renchang's view that the pteridophytes floristics in Mt. Taihang of Henan province should be classified into fern flora of North China.
