only reported drawback is a tendency to lose branches in 

 heavy winds. Messrs. Scharff & Shorting speak of this as 

 a weak point, but the vigor of the tree is so great that it 

 does not show any such effects in its present appearance. 



EUCALYPTUS GONIOCALYX, 



Eucalyptus goniocalyx is known as the blue gum of 

 New South Wales, where the Eucalyptus globulus does not 

 grow. It is spoken of by Von Mueller as one of the best 

 Eucalypti for forest planting. The wood is hard, tough, 

 and difficult to split and also exceptionally durable, both in 

 and out of the ground. It is one of the species of the 

 genus that has a particular tendency to vary especially in 

 its bark. In this respect it is sometimes of the Hemiph- 

 Ioi3e type and then called a box tree, and at other times 

 of the Leiophloiae, and then called a blue gum or white 

 gum tree. We have very few of them in California, in 

 fact I am certain of but one, that at the Forestry Station, 

 Santa Monica. This specimen in its buds, flowers, fruits 

 and foliage exactly corresponds to Von Mueller's plate. 

 There are several other older trees in different places that 

 come nearer to the botanic description of Eucalyptus gon- 

 iocalyx than to anything else and yet vary sufficiently from 

 them to suggest another species. Two of the. c e trees are 

 at Santa Monica Heights. Even these two vary from each 

 other in the fruits, but not in a very marked way. At a 

 casual glance these trees would be mistaken for Eucalyptus 

 globulus, although, of course, not at all like that in flower 



or fruit. I have never seen a botanic description of Euca-
