 opening by terminal slits. Pod flat, ij^ to 2 inches by

MIMOSE/E. 



In this family (or sub-order) of the LEGUMINOS^E 

 the flowers are small and massed in small dense heads or 

 short spikes ; the petals all equal, often united at the 

 base, and in bud valvate, none overlapping another ; 

 the stamens may be ten or very many. In other respects 

 the family is as given for the LEGUMINOS^ p. Q3 but in 

 many of the ACACIA genus the leaves are apparently 

 simple. 



Flower-heads globular : pod narrow ...... acacia. 



Flowers in thick spikes : pod very thin and broad . . albizzia. 



ACACIA. F.B.I. 50 cxxvii. 



Wattle, etc. 

 Flowers small in yellowish balls ^ inch across ; 

 calyx campanulate 1/16 inch; petals united in the 

 lower half ; stamens many. 



Species over 400. More than half Australian, the others in 

 the tropics. 



In many Australian species the leaves are apparently simple. Seed- 

 lings however all begin with bipinnate leaves, and the apparently simple leaf 

 is really a broadened leafstalk of which the pinnas and leaflets have not 

 developed : they are known 2,% phyllodes. It will be seen that the veining 

 of these is not like that of an ordinary leaf. 



There are no species indigenous to these levels, but three or four in- 

 troduced from Australia are now well established in and near hill stations.
