| 摘 要： | 文章报道了新种屏边开口箭T．pingbianensis J．L．Huang et X．Z．Liu及其核型和花粉形态。屏边开口箭的核型公式为2n=38=14m+lOsm+8st+6t，具明显的二型性，属3C型。花粉粒为球形，无萌发孔沟，外壁具皱块状纹饰。从花结构、核型和花粉形态上看，屏边开口箭和伞柱开口箭T．fungilliformis Wang et Liang亲缘关系近，而且伞柱开口箭比屏边开口箭在一系列特征上都较特化。

| Abstract: | A species of the genus Tupistra, T. pingbianensis J. L. Huang et X. Z. Liu, is described as new, and its karyotype and pollen morphology are reported. The bimodal kary-otype of this species is formulated as 2n=38 = 14m 10sm 8st 6t, and pollen grains are spheroidal, inaperturate, with rugulate exine sculpture. Based on its floral structure, kary-otype and pollen morphology, T. pingbianensis J. L. Huang et X. Z. Liu is considered phy-logenetically closely related to T. fungilliformis Wang et Liang. Whether the repense rhizome , solitary leaves of T. pingbianensis J. L. Huang et X. Z. Liu indicate a close relationship between the genus Tupistra and the genus Aspidistra needs further studies. |
