摘　　要：首次采用形态分类特征性状排序方法对玉兰属Yulania Spach35种植物进行了研究。结果表明,该法可作为该属植物物种鉴定和区别的有效方法之一,并将35种植物一一加以区别。同时,还可作为该属新分类群和属下分类系统建立的科学依据。如35种植物形态分类特征性状排序结果分为4类,其第1类至第3类,恰与玉兰属植物形态分类的玉兰组Sect.Yulania、渐尖玉兰组Sect.Tuplipastrum和朱砂玉兰组Sect.Zhushayulania相吻合;第4类,仅朝阳玉兰Y.zhaoyangyulan1个新种。此外,还纠正了一些错误。The taxis method of morphological classification characteristics was firstly used to differentiate 35 species of Yulania Spach.The results showed that this method was one of effective methods for identification and differentiation of plants of Yulania Spach,and also was a scientific basis for establishing of new classification group and classification system of Yulania Spach.For example,based on the taxis results,35 species were divided into four types.The first type,second type and third type accorded with Sect.Yulania,Sect.Tulipastrukm and Sect.Zhushayulania respectively which were from morphological classification.But the fourth type only included Y.zhaoyangyulan which was a new section.And this method also corrected several mistakes.
