对青冈亚属46种栎属植物的叶进行了研究。摘要对青冈亚属植物的叶构型进行了较全面的描述。研究了10个叶片构型特征，包括叶脉型、齿型、小巢、细脉和边缘末级脉序。四种类型的脉序模式和三种类型的牙齿被识别。文中还提出了脉序、齿型、第三脉、小网和细脉等叶构型特征的演化趋势。通过对青冈亚属、栎亚属和三棱栎亚属的叶结构比较，我们支持将青冈属作为栎属的一个亚属的分类处理，并推测青冈亚属在栎属中相对原始。(C)伦敦林奈学会
Leaves of 46 species of Quercus subgenus Cyclobalanopsis were studied. A comprehensive description of leaf architecture for subgenus Cyclobalanopsis is provided. Ten leaf architectural characters were examined, including leaf venation type, tooth type, areoles, veinlets and marginal ultimate venation. Four types of venation pattern and three types of teeth are recognized. Evolutionary trends of some leaf architectural features, e.g. venation pattern, tooth type, tertiary veins, areoles and veinlets, are suggested. Based on the comparison of leaf architecture of subgenus Cyclobalanopsis, subgenus Quercus and Trigonobalanus doichangensis, we support the taxonomic treatment of Cyclobalanopsis as a subgenus of Quercus and speculate that subgenus Cyclobalanopsis is relatively primitive within the genus Quercus.
