The size and localization of oil cells in the leaves, combined with the thickness of leaves, the number of layer of palisade tissue, the ratio of the thickness of palisade tissue to that of spongy tissue, the hypoderm, and the type of hairs, may be used as the identification characteristics of the generas, and even species.

木兰科植物油细胞的分布及其大小与叶厚、栅栏组织层数、栅栏组织与海绵组织厚度间的比值以及下皮层的有无、表皮毛的类型、叶脉的结构等特征相结合，可作为该科中属、甚至种的鉴别特征。

This study supports that genus Manglietia is the most primitive group in Magnoliaceae.

孢粉学资料证明木莲属是木兰科最原始的类群。

The sequences of segments of the trnL intron from 29 species and trnL-trnF IGS from 21 species of Magnoliaceae were analyzed. The results from the strict consensus trees were consistent with the former systems ① several species within the genera Michelia were homologious;② the subgenera Yulania was extremely homologious and much far from subgenera Magnolia;③ the species within Manglietia were highly conservative.

通过木兰科29个种的trnL基因内含子的525个碱基序列及21个种的trnL-trnF基因间隔区的370个碱基序列测定和分析，构建的严格一致性树建议：①含笑属为相对一致的单系类群；②玉兰亚属的几个种形成一个单系类群，与木兰亚属的几个种无共衍位点；③木莲属为个相对保守的类群，种间碱基差异很小。

A group of families or trees and shrubs and herbs having well-developed perianths and apocarpous ovaries and generally regarded as the most primitive extant flowering plants; contains 36 families including Magnoliaceae and Ranunculaceae; sometimes classified as a superorder.

一组乔木灌木和草本植物目，有良好的花被和心皮连生的子房，通常被视为现存最原始的开花植物；有36科，包含木兰科和毛茛科。

Moreover, the extended study has been conducted on several related families, including Magnoliaceae, a key family in angiosperm;Rhizophoraceae,Combretaceae,Lythraceae in mangroves, the important ecological plants.

以这一研究为基础，进一步开展了被子植物关键类群木兰科、重要经济生态植物红树林的主要类群红树科、使君子科、千屈菜科等类群的分子系统学与进化研究，获得了很有意义的结果。

Further study was carried on the cpDNA matK in Hamamelidaceae and its systematic significance (the sequences of matK of some species have been obtained, and the research have been funded by NSFC), and molecular and systematic study were also carried on Magnoliaceae, Rhizophoraceae, Labiatae.

在此基础上，开始了对金缕梅科叶绿体DNA mtK基因及其系统学意义的研究（已测定部分种类的matK基因序列，并获国家自然科学基金国际合作项目的连续资助），同时对木兰科，红树科，唇形科植物类群开展了分子系统发育研究。
