| 摘 要： | 目的]为山茶属（Camellia）短柱组（sect.Paracamellia）的系统分类获得新的系统学证据。方法]对短柱茶组10种植物进行了果实解剖特征研究,并应用MVSP软件对短柱茶组进行了主成分分析。结果]外果皮很薄;中果皮宽广,为多列薄壁细胞,并有大量石细胞;内果皮木质化,极易与种子分离。主成分分析表明,物种之间的距离较远,显示出物种之间的较远亲缘关系;不支持闵天禄将长瓣短柱茶（C.grijsii）归并入攸县油茶（C.yuhsienensis）,也不支持将陕西短柱茶（C.shensiensis）作为攸县油茶变种;小果短柱茶（C.confusa）与落瓣短柱茶（C.kiss）之间差异很显著,将其合并是不自然的。结论]为短柱茶组植物资源的开发和应用提供了理论依据。

| Abstract: | Objective] To utilize the germplasm resources,new systematic evidence for the classification of sect.Paracamellia,genus Camellia is found in this article.Method] Fruit anatomy of 10 species representing sect.Paracamellia was investigated.And the main component of sect.Paracamellia in the genus Camellia was studied by MVSP software.Result] The exocarp was thin;mesocarp was broad,having a large number of stone cells;endocarp was lignified,and separated easily from seed.The principle components analysis suggested that the distance between species was far,showing far relation;the current study did not support the formation of Camellia grijsii（C.grijsii）and Camellia yuhsienensis（C.yuhsienensis）,Camellia shensiensis（C.shensiensis）should not be recognized as a variety of C.yuhsienensis.In addition,it also proved Ming＇s combining of Camellia confusa（C.confusa）and Camellia kissi（C.kissi）was unnatural.Conclusion] The study provided theoretical basis for the development and application of sect.Paracamellia in the genus Camellia. |
