栎属Quercus隶属壳斗科Fagaceae,是本科在我国分布最广的属,几乎遍布全国。栎属原包括栎类和青冈类植物,早在1866年Oerst把青冈类植物从栎属中分出来,成立了青冈属Cyclobalanopsis。一百多年来有人主张合并,有人主张分开,直到今天分合仍然未定。而从形态上和地理分布上青冈属与栎属皆有明显的区别,根据人们的习惯认识,笔者认为将它们分别独立成属是十分必要的。
Quercus Quercus under the Fagaceae Fagaceae, is the most widely distributed genus in our country, almost all over the country. Quercus originally includes oaks and glauca plants. Cyclobalanopsis was established in Oerst in 1866 to separate Cyclobalanopsis from Quercus. For more than a century people advocated the merger, some advocating division, until today, still not yet determined. From the morphological and geographical distribution of Cyclobalanopsis and Quercus are obviously different, according to people’s habits, I believe that it is necessary to separate them into a genus.
