This article presents the results of a study on seed coat micromorphology and epicuticular structure of Ginkgo biloba cultivars. The micromorphology of the seed coat of 10 cultivars and one clone of female G. biloba were analysed. The taxa differed in the size and shape. Homogeneous epicuticular wax deposited in the form of wax tubules on the sarcotesta and sclerotesta surfaces. There were great differences in wax between the outer and inner layer of the sarcotesta. In the endotesta wax was diversified in the form of tubules, platelets or it was mixed. The article includes descriptions and illustrations of several micromorphological features which have not been published previously. The results of the SEM and LM investigation confirmed the taxonomic significance of the micromorphological traits in the Ginkgo genus. In the seeds many characters are present in of all the taxa and may be typical of Ginkgo.
