 growth of a beautiful golden colour, during the spring and 

 "summer months.

 remarkably bright-green colour ; the secondary branchlets and 

 small spray are short, crowded, four-sided, and of a very bright 

 green; the leaves are ovate, a little pointed, closely and regularly

 with a portion of the lesser branchlets of a rich golden colour.
