[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. 展开更多
