| 摘 要： | 根据多年来对厚朴组树种的观测，以及对厚朴芽、枝形态与解剖特征、枝型与叶位关系的研究，论述了厚朴组叶位问题，提出该组树种春叶集生春枝上，即春叶集生当年生枝基，夏、秋叶在夏、秋枝上互生并有小形叶和畸形叶，长萌枝、苗干叶互生的观点。这一结论纠正了长期以来厚朴组“叶假轮状集生于枝端”的错误记载。 |

| Abstract: | The results about the leaf site of section Rytidospermum Spach of Magnolia was reported in this paper,which are different from that described by predecessors.The results show that the spring leaves of sect.Rytidospermum are clustered in spring branches,which means spring leaves clustered in the bases of the branches,but not the ends of the branches,that the leaves of the summer and autumn are alternate,also are the leaves of seedling and long sprouted branches.The results are verified by the morphology and anatomy of the bud and branch. |
