 with it the dubious corolla, which is intimately united to it on its inside. 

 Thus, what is left is the lower part of the calyx, which is really a 

 woody cup, with its pistillate organs in the centre. But, though a 

 cup-like body, it has four rib-like markings on the outer side, which

plainly indicate the sepaloid divisions. Look at the fruit, or seed- 

 capsule, which is given about the natural size at the bottom and to 

 the right of Fig. 3. Bristling from the inner rim or edge of the calyx, 

 stand the thread-like stamens, each with its golden anthers atop, 

 making a showy display for what would otherwise be, from its extreme 

 simplicity, a very unhandsome flower. 



The growth of the young eucalypt affords some points of strange in- 

 terest. There is the rapidity of growth of the three species which have 

 been best tried, and which certainly will figure largely as the world's 

 future timber-trees : E. globulus, the blue-gum ; E. gigantea, the 

 stringy-bark ; and E. amygdalina, the messmate, or peppermint-tree.
