Acacias (wattles) are widespread in Australia. Most acacias, and all in the Westonia Town Common, have distinctive yellow flower heads. The flower heads are usually globular or rod-shaped. Each head is made up of many tiny flowers. The leaves are flattened stalks called phyllodes. Acacias come in many forms from low shrubs to trees. The shrubs are often spiny. The word 'acacia' originates from the Latin word for a pointed instrument: acis.
Pea flowers have a distinctive shape. Typically, there are 5 differently shaped petals. The standard is at the back, two wings oriented forwards, and below them a tube-shaped keel which contains the stamens.
Wattles and Peas all the belong to same plant family: FABACEAE. All the species have seed pods with the seeds attached along one side (like garden peas) The pods can vary a lot in shape and also can be straight or twisted.
