Abstract: The spores of 4 species of Adiantum L., Adiantum capillus-junosis Rupr.A.edgeworthii Hook., A.pedatum L.and A.capillus-veneris L.were systematically observed under SEM and LM as supplementary instrument in this paper.The morphological characters of the spores were described in detail.Difference of the spore morpholog, especially in the characters of perine and ornamentation, was discussed and can be take as evidence of pellenic of classification among 4 specics.

Key words: Adiantum L., Spore morphology, SEM.
