摘要
化龙山共有蕨类植物２６科、４６属、１１４种。本文对该区蕨类植物的科、属、种进行了统计，其区系地理成分可划分为８个类型。本区与我国８个山地蕨类植物区系比较表明，化龙山与神农架关系密切，属同一自然区，与其它山地较为疏远。
There are 26 families, 46 genera, and 114 species (induding varieties) of pteridophytas in Hualong mountain. The families, genera, and species of pteridophytas are classified and the geographical elements of pteridophytas are analyzed. The flora of pteridophytas can be divided into 8 areal types. In contast with 8 other mountains in China, the floristic elements of Hualong mountain are similar to Shennongjia, and they should be the same natural flora, but scarcely to the others.
