| 摘 要： | 研究了毛茛科鸭(足石)花属Oxygraphis Bunge 3种植物的核形态。其间期核均为复杂中央染色微粒型,前期染色体为中间型,染色体基数为x=8。脱萼鸭（足石）花O.delavayi的染色体明显大于鸭(足石)花O.glacialis和细叶鸭(足石)花O.tenuifolia的染色体。结果支持鸭（足石）花属是毛茛科毛茛亚族subtrib.Ranunculinae的一个自然成员以及脱萼鸭跖花可能是该属的原始种的观点。

| Abstract: | Three species of the genus Oxygraphis Bunge (Ranunculaceae) were karyomorphologically studied. The interphase nuclei of complex chromocenter type, prophase chromosomes of interstitial type and basic chromosome number of x=8 were common to all the three species examined, but the chromosomes of O. delavayi were markedly larger than those of O. glacialis and of O. tenuifolia . The results support the viewpoints that Oxygraphis is a natural member of the subtribe Ranunculinae Spach, tribe Ranunculeae DC. in the subfamily Ranunculoideae and that O. delavayi might be the primitive species of this genus. |
