Abstract: C. Juzepcuk, in the flora of the USSR X, had divided Sibbaldia L. (sensu lat.) into three genera: Sibbaldia L. (sensu ang.), Dryadanthe Endl. and Sibbaldianthe Juz., based on the number of stamens (5 or 10). We have discovered, however, that the number of floral parts of S. pentaphylla J. Kraus from China is both 4 and 5. We have also found two new species, S. pulvinata Yü ti et Li and S. glabriuscula Yü et Li, to have 5-7 stamens. For this reason, we have to accept a wider genus-Sibbaldia L. (sensu lat.). In the present paper, four new species are described and the description of S. pentaphylla J. Krause is amended.
