 the illustration (plate 47). 



Eucalyptus maculata var. citriodora, the lemon-scented gum, is a rather 

 slender, straight-stemmed tree, with long, slender, drooping branchlets,

 lemon-scented. The habit of the tree is graceful. Here it shows a

 breeze, like the apricot. It will stand some frost, being hardy at Oak- 

 land, Cal. It furnishes a useful timber, and deserves a place in any 

 collection of ornamental trees. 



PLATE 48. EUCALYPTUS ROSTRATA, OR "RED GUM." 

 A very hardy and valuable timber tree. 



Eucalyptus rostrata, the red gum, has been very generally confused 

 in this State with E. viminalis, a much inferior tree. E. rostrata is a 

 fast-growing tree of erect habit, with persistent, smooth, gray bark, and 

 drooping foliage of a grayish-green color. The blossoms are creamy 

 white, small and in small clusters, produced freely in early summer. 

 The tree endures extreme heat, resists frost better than many eucalypts, 

 and stands considerable drought without suffering. Its timber is hard, 

 strong, and durable. It has been alleged that the blossoms of this
