Abstract: Pteris fauriei complex includes Pteris fauriei,P. fauriei var. chinensis,P. angustipinnula,P. majestica,P. splendida and so on. The taxonomic cluster of the complex is easily confused due to the morphological similarity of the members of the complex. Morphological observation of the spores of five members in this complex was performed by a scanning electron microscope（ SEM）,which could help to clarify their genetic relationship. It was found that the lophate-like ornamentation is an important feature,The complex could be divided into four groups based on the presence and distribution of the lophate ornamentation. And the spore morphology is species-specific in the complex,except in that P. fauriei and P. fauriei var. chinensis shared similar spore morphology and are hard to distinguish from each other. In addition,the "conjoined spores"phenomenon was first found in P. splendida.
