430 FLORA OF MADRAS. [Acacia. 



tree with silvery foliage of bipinnate leaves which do not change 

 into phyllodes, yellow very sweet-scented panicles and heads of 

 flowers and narrow pods, the sutures not or little constricted 

 between the seeds. It is largely grown in coppice as a fuel, and 

 the bark is a useful tan, not so valuable, however, as that of the 

 very closely allied A. deciirrens, Willd., which has also been 

 planted to a small extent. It differs by the foliage not being 

 silvery and the pods distinctly constricted between the seeds.
