Abstract:The morphology of spores of 7 genera,34 species of Aspidiaceae from China was examined using scanning electron microscope (SEM).The spores of Aspidiaceae are monolete,bilaterally symmetrical and the aperture is 1/2～2/3 of the spore diameter.The spores are often elliptic in polar view,and hemispheric,super hemispheric or fabiform in equatorial view.The length of polar axis is about 18～38 μm.The length of equatorial axis is about 23～57 μm.The spore ornamentations of Aspidiaceae are divided into four types.i.e.Lophate,Alate,Echinate and Auriculate.Sometimes there are spinelets,particles and holes on surface ornamentation.The classification of Aspidiaceae based on the spore morphological characters differs from that based on the sporophyte characters.The ornamentations types are interlaced between genera of Aspidiaceae.MAARTEN J.M was supported to redistribute Aspidiaceae and Dryopteridaceae.
