| 摘要: |
| 通过野外和标本室观察,发现凤凰蜘蛛抱蛋的原始描述存在一些错误。重新详细描述了该种的花部形态特征,补充了果实形态特征的描述,并首次报道了其染色体数目(2n=38)和核型(2n=22m+6sm+10st)。根据核型特征,认为该种的近缘种应为四川蜘蛛抱蛋和乐山蜘蛛抱蛋,而非黄花蜘蛛抱蛋。 |

| Abstract: |
| Based on both field and herbarium observations,some mistakes were found in the original description of Aspidistra fenghuangensis K.Y.Lang,a species currently only known from Jishou and Fenghuang,western Hunan Province,China. The flower and fruit characters of this species were re described in detail.Its chromosome number,2n=38,was reported here for the first time. Its karyotype is bimodal and formulated as 2n=22m+6sm+10st. The karyotypic data indicate that A.fenghuangensis K.Y.Lang is more closely related to A.sichuanensis K.Y.Lang & Z.Y.Zhu and A.leshanensis K.Y.Lang & Z.Y.Zhu than to A.flaviflora K.Y.Lang & Z.Y.Zhu. |
