Albizzia Ubbek is an ornamental tree that is exceedingly good for avenues. Its roots 

 do not penetrate very deep. It grows rapidly, flourishes in almost any soil, and may 

 be propagated by cuttings. The wood s(^asons, works, and polishes well and is fairly 

 durable, while the l)ark is used as a tan bark. From this tree is procured a gum that 

 is said not to be soluble in w^ater, but to merely form a jelly; it resembles gum arabic. 



Local names, amor plaLonico, Jlambotjdn. The last name is used for Albizzia lebbek, 

 as well as for Poinnana regia, according U) Urban,
