摘要
对广西蕨类植物区系的组成、特征、区系地理成分作了详细阐述。该蕨类区系十分丰富 ,现已发现 5 6科、1 5 8属、85 4种 (变种、变型 )。区系地理成分复杂 ,属划分为 1 4种类型 (变型 ) ,种划分为 1 8种类型 (变型 )。文中对该区系的性质进行了探讨 ,认为该区系是热带向亚热带过渡的植物区系 ,南部具有热带性质 ,北部具有亚热带性质 。
The taxon numbers,characteristics and distribution types of Guangxi pteridophyte flora are discussed in present paper. The flora is very rich in families,genera and species,in which 584 species represented 158 genera and 56 families. The genera and species distribution types are divided into 15 and 18 types respectively. The nature of the flora is studied.
