wattles, and they are best discussed as they 
occur in the key given below. 
Acacia rupicola and Acacia vomeriformis 
form a sub-group by reason of their having 
rigid and pungent-pointed phyllodes. 
Acacia rupicola is a small shrubby wattle 
which I have seen only in Morialta Gorge. 
Its phyllodes are linear (i.e. narrow-lance- 
shaped), and if the pods are ripe you will 
note that the seeds have a broad aril, i.e. 
aril. 
The remainder of our wattles all have thick, 
pliable phyllodes, which are neither stiff nor 
pungent-pointed. They are subdivided ac-

are borne. In the first group, with four 
species, each globular head has a stalk of 
its own, that is, it is pedunculate. Groups 
of heads, or two (twin) heads, may grow from 
the axil of the same phyllode, or there may 
be only one head to each axil. But each
