关于一些植物学术语的中译等问题（二）

ON SOME BOTANIC TERMS Ⅱ

（１）在各种花对称的分类中，Ｅｈｒｅｎｄｏｒｆｅｒ的分类包括了被子植物花对称方面从原始到进化的各种类型，最为全面广德国学者Ｓｔｒａｓｂｕｒｅｒ在１９１１年编著的第１１版植物学教科书中将具２对称面的荷包牡丹属的花称为ｂｉｌａｔｅｒａｌ或ｄｉｓｙｍｍｅｔｒｉｓｃｈ．这个类型代表了被子植物花的一种较进化的构造，应该予以肯定。由于被指定为描述具２对称面的花的术语ｂｉｌａｔｅｒａｌ与被指定为描述具丑对称面的花的术语ｂｉｌａｔｅｒａｌｌｙｓｙｍｍｅｔｒｉｃａｌ颇为相似，而易引起混淆．为避兔发生混淆．建议不再应用这二术语．在描述具２对称面的花时，选用ｄｉｓｙｍｍｅｔｒｉｃａｌ，中文译为双面对称的，在描述具１对称面的花时，选用ｚｙｇｏｍｏｒｐｈｉｃ（左右对称的）或ｍｏｎｏｓｙｍｍｅｔｒｉｃａｌ，后者的中文可译为单面对称的。（２）赞同将术语ｔｅｐａｌ译为花被片，而不赞同译为“被片”。

The classifications of floral symmetry proposed by various botanists are briefly reviewed,Of them the classification made by F. Ehrendorfer is considered the best, thoroughly showing the various types, primitive and advanced,of floral symmetry of the angiosperms.The flower of the genus Dicenfra (Papaveraceae) with two symmetrical planes was described as bilateral or disymmetrical by the famous German botanic text-book,Strasburgor's Lehrbuch der Botanik'in 1911. This more advanced distinct type of floral symmetry,though being neglected by many botanists for many years, should certainly be accepted.For eliminating the confusion,which may be caused by the utilization of two very similar terms‘bilateral’,assigned to denote the flower with two symmetrical planes as mentioned above, and ‘bilaterally symmetrical’,assigned to denote the flower with one symmetrical plane, it is better to cease to use these two termes. For replacing the term‘bilateral’,the other one‘disymmetrical’may be selected, and for describing the flower with 1 symmetrical plane,the terms ‘zygomorphic’or‘monosymmetrical’may be used. (2 ) The Chinese translation'for the term‘tepal’is discussed.
