It is a shrub or small tree belonging to that group of trees known as 

 the Bull Horn Acacias, so-called from the large hollow spines with flar- 

 ing bases along the branches, and in which ants live. These animals are 

 pugnacious with a strong sense of proprietorship and rush forth from 

 their spine retreats to attack anything that disturbs their arboreal world, 

 botanists included. This species is found in the more open forests and 

 along stream banks and is tolerant to a wide range of soils.
