The seed cases or fruit ot the blue gum, in sorr.e 

 places, change color after they fall. I have several times 

 made collections of them at Santa Monica to enjoy the 

 brilliant and beautiful shadings of color that these assume 

 and for a considerable time maintain. 



The Eucalyptus flowers have no ornamental petals. 

 Their form and coloring depend on the numerous stamens. 

 Most of them look like beautiful pompons. The blue gum 

 flowers are decorative and striking, especially when natur- 

 ally surrounded with the sickle-shaped leaves. These 

 flowers have the filaments white, and the anthers a delicate 

 cream yellow. The general appearance is white. 



The stem, as has been said, is deeply grooved on the 

 four sides in the young square stage. Upon this the oppo- 

 site sessile leaves are placed in pairs, alternately springing 

 from one side of the square and then from the other. The 

 stem often, however, has a spiral twist, in which case the 

 alternate effect of this placing is lost. 



In this young stage a small stipule accompanies each 

 leaf. Quite often this stipule grows and branches out, and 

 founds new branches.
