Populus, Tournefort. Some derive the word 

 Populus from paipallo, to vibrate or shake ; 

 others suppose it obtained its name from being 

 used in ancient times to decorate the public 

 places in Koine, where it was called arbor p6- 

 puli, or the tree of the people. Linn. 22, Or. 



7, Nat. Or. Salicaceoz. Most of the species of 

 poplar are very ornamental, more especially in 

 early spring, when the catkins of the males 

 are produced. Their favourite place of growth 

 is in moist soil near a running stream ; but 

 they do not thrive in very marshy situations. 

 All the species are readily increased by cut- 

 tings or layers, and some by suckers. Syno-
