Key based on Vegetative Characters

All main foliar structures are treated as leaves or leaflets
( in the case of certain Acacia spp., the 'leaves' are actually phyllodes); refer to the introduction and glossary.

In the few instances where supplementary flower and fruit characters have been utilized they are always given last [in square brackets].

Herbaceous species may on occasion cause difficulty by becoming "woody" and shrub-like when fully grown.
Refer to the introduction and glossary.

A month is given in parentheses, ie. (Nov), immediately following each lead; the earliest month to find the taxon in flower.
Refer to the introduction and glossary.
