3 8 EUCAL YPTUS. 



the Australian bush I have not observed insects injuring 

 the Eucalyptus. 



In South Australia Eucalyptus leucoxylon is called blue 

 gum and in New South Wales Eucalyptus goniocalyx goes 

 by the same name. Eucalyptus globulus is not indigenous 

 to South Australia and is not a feature of the forests of 

 New South Wales, except perhaps in a small far southern 

 district adjacent to Victoria. Both of these species are hardy, 

 fast growers, and valuable timber trees. In various dis- 

 tricts the name blue gum is locally given also to Eucalyp- 

 tus haemastoma, Eucalyptus megacarpa, Eucalyptus rud : s 

 and to Eucalyptus saligna. Again, in other districts these 

 trees have different popular names as may be seen by an 

 accompanying index of Vernacular names taken from Von 

 Mueller. 



Eucalyptus globulus may always be distinguished by its 

 glandular appearing fruits. These are of an unhealthy, 

 bluish-white color until the seeds are fertilized. The col- 

 oring suggests a case of erysipelas painted with nitrate of 

 silver. There is only one other species of Eucalyptus that 

 has this rough, glandular seed box. This is Eucalyptus 

 Alpina, a bush restricted in its native habitat to a few 

 acres on Mt. William, in the Grampian Range, Victoria. 

 Eucalyptus Alpina is the closest botanic ally of Eucalyptus 

 globulus and still while the blue gum is the fastest grower 

 of the genus, the Alpina is the slowest ; while one is a 

 giant tree, the other is a dwarf bush ; while one is intro- 

 duced into every section where the climate permits, the 

 other is but a curiosity, A Eucalyptus Alpina planted in 

 the botanic garden, at Melbourne, grew twelve feet in 

 twenty-five years and had no central stem. When we 

 consider the systemic affinity of these two species and
