A putative natural double-flowered hybrid in Lycoris Herb. was found on Mt. Zhangjiajie in Hunan, China. The putative natural hybrid had a chromosome number of 2n = 18 and was karyotypically formulated as 2n = 4m + 6st + 5t + 3T. The karyotype of the putative natural hybrid was classified as 2B type according to the degree of asymmetry and Stebbins’ criteria. According to the gross morphology, phenology and karyotype of the putative natural hybrid, it was suggested that this taxon was probably from the natural hybridization between L. aurea and L. radiata.
