The extraordinary keeping power of the seed is striking. Con- 

 sider, for example, E. amygdalina: seed of the 1904 crop germin- 

 ated 90 % even after 4 years, and the same is the case with E. 

 gigantea, E. globulus and E. Gunnii. The seed weight as well as 

 the number of seeds per kilogram refers here, as everywhere, 

 only to the pure seed, not to the real value; for Eucalyptus seed 

 is very often impure, since it contains a great deal of the remains 

 of the fruit capsules as with Alder and Birch seed, so that seed 

 with 70, 80 to 90 % germinating capacity has usually only a real 

 value of 1520 / .
