亮果桉[Eucalyptus nitens(Deane ＆ Maiden)Maiden]在分类学上与蓝桉(E.glo-qulas Labill)和多枝桉(E.viminalis Labill)亲缘关系密切,同属于双蒴盖亚属(Sgm-phyomyrtus)蓝桉组。亮果桉是桉树属中高大乔木树种之一,是澳大利亚高大桉树林的重要组成树种。树高通常40-70m,偶见高达90m,胸径1-2m,树干饱满通直。亮果桉的地理分布呈现出典型的地理间断特征,种群之间彼此隔离,因此其形态特征,尤其是幼态叶的特征产生明显的种内地理变异。它分布在澳大利亚的新南威尔土和维多利亚4个相互隔离地区。水平分布的地理纬度范围为30°-38°S,垂直分布海拔
Eucalyptus nitens (Deane & Maiden) Maiden is taxonomically closely related to E.glo-qulas Labill and E. viminalis Labill, belonging to the genus Sgm-phyomyrtus) Eucalyptus group. Eucalyptus is one of the tall tree species of Eucalyptus, which is an important tree species of tall eucalyptus forest in Australia. Tree height is usually 40-70m, occasionally up to 90m, DBH 1-2m, full trunk straight. The geographical distribution of bright eucalyptus showed a typical geographical discontinuity, and the populations isolated from each other. Therefore, the morphological characteristics of the bright eucalyptus, especially the characteristics of young leaves, had obvious intraspecies variation. It is located in New South Wales, Australia and Victoria, four separate areas. Horizontal geographical latitude range of 30 ° -38 ° S, the vertical distribution of elevation
