Introduction

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.
