Introduction
Key
Glossary
Checklists
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.
