摘  要:
运用数量分类的方法对长苞铁杉Nothotsuqa lonqibracteata(Cheng)Hu ex C.N.Page(Tsugalonaibracteata Chena),云南铁杉Tsuqa dumosa(D.Don)Eichler,北美大果铁杉T.mertensiana(Bong.)Carr.,油杉Keteleeria fortunei(Murr.)Carr.,黄杉Pseudotsuga sinensis Dode等11个分类单位,选取了28个性状进行分类学研究。结果表明,长苞铁杉距离系数大于属的分割线值0.513,从而支持成立长苞铁杉属的观点。对铁杉属的8个种作了分组的讨论,根据聚类分析的结果,该属应划分为3个组:Sect.1 Tsuga;Sect.2 Canadensis Sect.nov,;Sect.3 Hesperopeuce Engelm.

摘  要:
28 characters of 11 taxa classifical units Nothotsuga longibracteata, Tsuga dumosa, T. mertensiana, Keteleeria, Pseudotsuga and so on are selected for the research of numerical taxonomy. Between longibracted Hemlock and other species of Tsuga there are distinct differences on form and the feature of anatomy with the distance coeffient more than the numerical value 0. 513 carve up line of the genus. The outcome of the numerical taxonomy supports the standpoint of the establishment of the genus Nothotsuga. According to the outcome of cluster analysis, Tsuga should be divided into 3 sections: Sect. 1 Tsuga; Sect. 2 Canadensis nov. sect, and Sect. 3 Heperopeuce Engelm.
