%X We observed the leaf epidermis characters in 7 subgenera, 12 species of <i>Ribes</i> L. using scanning electron microscopy(SEM). The epidermis cells were irregular polygon in shape. The patterns of anticlinal wall are straight-blow, sinuolate or sinuate. The cuticular layer of the leaf epidermis is usually smooth or nearly smooth, with few apophysis of mastoids. The trichomes are nonglandular hair and glandular hair. There are peltate glandular hairs in <i>R.nigrum, R.procumbens</i> and <i>R.graveolens</i> with different densities. We supported the treatment of the Ser. <i>Nigra</i> Pojark. as the subg. <i>Coreosma</i>. The stomata type is anomocytic in all observed species, the shape was round or oval. Most species were hypostomatic.
