Abstract: A quantitative taxonomic study was conducted on cultivars of Chimonanthus praecox using cluster analysis. The selected 14 morphological characters of 45 cuhivars were investigated. The results showed the length of the middle whorl of petals and the purple texture of the inner whorl of petals were important characters. In this paper, it was suggested that the purple texture of the inner whorl of petals could be used to divide Chimonanthus praecox cuhlvar group.
