So generally cultivated for the perfume of its flowers and so frequently established 

 as an escape from cultivation, that it is difficult to determine where it is really indige- 

 nous. It appears, however, to be so in western America, from northern Chile to Texas, 

 not, perhaps, in Brazil nor Guiana. 



Abundant in tropical and subtropical northern central Australia, and in the interior 

 of northeastern Australia, and perhaps also really indigenous in south tropical Africa, 

 but introduced only in East India, northern tropical Africa, and the Mediterranean 

 region. 



The roots and pods of this plant have an alliaceous odor and in the Antilles are used 

 for tanning, dyeing black, and in baths. The fragrant flowers (in trade falsely known 

 as cassia flowers cassie of the French) are much used in the making of perfumery. A 

 gum exudes from the stem in considerable quantities. It is considered superior to 

 gum arabic in the arts and in medicine. The wood is white, close-grained, hard, and 

 tough. 



Local name, aromo. 



3. Acacia nudiflora Willd. 



(Urban, 266.) 



Tree 8 to 15 meters high; flowers white or yellow-white, later becoming brown;

 wide, the valves coriaceous.
