[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.

[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.
