Taxonomic studies of 11 taxa in Hemerocallis from China were conducted using cluster analysis and principal components analysis. The taxa were grouped into four clusters. The Cluster one includs H. citrina, H. lilioasphodelus, H. minor and H. multiflora ; the second cluster H. dumortieri and H. middendorfii; the third cluster H. plicata, H. for-resti and H. nana ; and the fourth cluster di-and triploid of H. fulva . Relationships between the taxa within clusters as well as the subdivision of the genus are discussed.
