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

 as an escape frcun eullivation, that it is dillicult 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 nortluTu central Australia, and in the interior 

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



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

 ri'gion. 



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 arable in the arts and in medicine. The wood Is white, close-grained, hard, and 

 tough. ■ 



Local name, aronio.
