Abstract: Two cultivars of Narcissus tazetta L., the single flowered formand the double floweted form (i. e. "Dan-ye-shui-xian" and "Bai-ye-shui-xian" by local names), have long been cultivated in Zhangzhou, Fujian. The former has a fertile flower with a cup corona. while the latter has a sterile flower with a split corona and petaloid stamens, which is seldom seen in the flowers of the genus Narcissus L., Observation on both the cultivars shows that they have the same number of chromosomes and the inflorescence and flower are much alike. Therefore the double flowered cultivar is believed to have probably derived from the single flowered cultivar, and this character of split ocrona, thouth pointed out to be aprimitive one by M. G. Zandbengen, is supposed to be a phenomenon of reversion. The number of the chromosomes observed in the bulbs of these two cultivars are 2n=14, which is just the same numberas an Indian variety N. tazetta L. var. ponterius. A. K. Sharmaet A. Sharma regarded the Indian variety as the link with other species (2n=14) of Narcissus. The occurrence of fourteen chro-mosomes in diploid, as observed here, is obviously one of the original chromosome numbers in N. tazetta L.. for the occurrences of 2n=21 and 2n=28 chromosomes in some varieties have been reported previously by many authors. These chromosomes are conspicusouly the triploid or tetraploid from x=7 in the aggregate species of N. tazetta L.. N. tazetta L. var. chinensis J. Roem. means a native variety in China. Some authors have also reported that N. tazetta L. is distributed from Europe to China and Japan. Others have been unable to judge whether it is right or wrong. Weng Guo-liang (1936) made a mistaken report base on an ancient poem that the Narcissus was an original species in Wudang mountain, Hubei province. According to the floristic view-point, Narcissus L. is an endemic genus in Mediterranean region, compricing 30-40 species distributed from Mediterranean to middle Europe and N. tazetta L. is of just an Eumediterranean element. But, as the mater of fact, it is impossible to be scattered disjunctly in wide area from Europe to Eastern Asia. It is not a natural wild Narcissus but an escape form in a state of wild Narcissus discovered in several islands in East China and off the sea shore of Japan. We agree with B. Laufer (1919) that Chinese Narcissus was introduced from Ancient Persia. On the basis of historical data. Quanzhou (Fujian) and Yangzhou (Jiangsu) both cities were the important harbors of international trade between China and Ancient Persia in the Tang and Song (Sung) dynesties, and Narcissus might have been introduced in that time. The name of N. tazetta L. var. chinensis J. Roern. must be reduced as asynonym of N. tazetta L..
