摘要：Based on the significance of palynology in plant taxonomic identification, the purpose of this paper is to provide palynology basis for taxonomy, interspecific identification and resource protection of Ceratopteris Brongn. plant system. The spores of C. thalictroides and C. pteridoides of domestic Ceratopteris Brongn. were observed and compared by scanning electron microscope. The two types of spores of Ceratopteris Brongn. are radially symmetrical, tetrahedral, trilete suture, spherosome in polar view and equatorial view, and have common morphological characteristics such as perispore and ridge-like bulge of perispore, but there are obvious differences such as density of ridge-like bulge and ornamentation among bulges between two types of spores. The spore morphology is of great significance in the interspecific taxonomy of Ceratopteris Brongn.. It does not only provide the palynology scientific basis for the taxonomy and identification of Ceratopteris Brongn., but also provides a series of feasible measures for the exploitation and the resource conservation of Ceratopteris Brongn..
