From Pathfinder Wiki

12. Make a collection of 10 or more dried pressed wattles with flowers and phyllodes and where possible pods and seeds. Show dates, place collected, common and scientific names. Some must be spike type flowers, some raceme type or single balls and some bipinnate leaves.
OR

20 or more close-up photographs you have taken of wattles showing the above details.

The best approach to this requirement is to go out into the field and find some wattles - then identify them. There are numerous books and CDRoms available for purchase that will help in identifying the various species. There are also a few dichotomous keys online, such as this one which are free (though not necessarily easy to use).
