8. UETICACE^E (Urtica urens) Stinging Nettle. 

 (Humulus lupulus) Hops. 



The Nettle in Australia grows 

 to the size of a tree ; the Hop 

 also belongs to this order, and 

 is largely cultivated in Kent 

 and Sussex for the use of 

 brewers, as it communicates an 

 agreeable bitter to beer which 

 no other plant seems to be able 

 to substitute. 



Hop. 



9. SALICACE^E (Salix alba) White Willow. 



(Populus nigra) Black Poplar. 



The most characteristic of this 

 order are the examples given ; 

 the Willows are well-known 

 trees, growing by the margins 

 of water and in damp places. 

 The Poplar is one of our tallest 

 trees, specimens being known 

 100 feet high ; its peculiar tall 

 form distinguishes it from all 

 other trees.
