长期以来,对高山三尖杉(Cephalotaxus alpina(Li)L.K.Fu)分类地位的争议缺少可靠证据。本文从居群采样的水平上比较了高山三尖杉和三尖杉(Cephalotaxus fortunei Hooker)的叶片和种子形态特征,两者除种子的长宽比率无显著差异外,种子长度,宽度,厚度,长厚比率,宽厚比率以及叶片长度和宽度均差异极显著。此外,通过散点图分析表明两者的种子宽厚比和叶片宽度的变异是间断而稳定的,这一特征能将高山三尖杉和三尖杉明显地区分,结果支持将高山三尖杉作为种的等级较为合适,不赞成将高山三尖杉作为三尖杉的变种或亚种的分类处理。同时,对标本和原始文献的研究认为胡秀英(1964)发表的园桃杉(Cephalotaxus fortunei Hooker var.globosa S.Y.Hu)和高山三尖杉应是同一分类群。
For a long time, the dispute over the taxonomic status of Cephalotaxus alpina (L.) L.K.Fu lacked credible evidence. In this paper, the morphological characteristics of leaves and seeds of Cephalotaxus fortunei Hooker were compared at the level of population sampling. The seed length, width, thickness, The ratio of length to thickness, ratio of width to thickness, and leaf length and width all have significant differences. In addition, scatter plot analysis shows that the seed width-to-thickness ratio and leaf width variation between the two are intermittent and stable, this feature can be clearly Cephalotaxus Cephalotaxus and Cephalotaxis, the results support the use of Cephalotaxus as Kind of the appropriate level, not in favor of the Cephalotaxus as Cephalotaxus variant or subspecies classification treatment. In the meantime, the study of specimens and original documents suggests that Cephalotaxus fortunei Hooker var. Globulosa S.Y.Hu published by Hu Xiuying (1964) should be in the same taxa.
