FLOWERING TREES AND SHRUBS 107 



Linum (Lineae). 



Lindm arboeeum. — Greece, 1788. A neat-habited, small-

 its golden flowers. Being an evergreen, and rarely exceed-

 instances, the branch tips being killed back. As a pot or 

 tub shrub it does well. Propagated readily from cuttings 

 placed in a cool frame or under a hand-light. 



Liriodendron (Magnoliaceae).

 The large, four-lobed, truncate leaves, of a soft and pleasing 

 green, are highly ornamental, and are alone sufficient to 

 establish the identity of the tree. Flowers large, yellow, 

 variegated with green and orange, and sweet-scented, and 

 usually freely produced when the tree has attained to a 

 height of between 20 feet and 30 feet. When we consider
