Flower heads come from the upper angle between the leaf or phyllode and the branchlet i.e. they are axillary. Pair of single globose flower heads, each on a stem, each coming from a single common axillary shoot. Ball flower heads, solitary, from a phyllode axil Rod flower head and a phyllode with 3 veins or nerves Flowers are actinomorphic, ie. The calyx and corolla valvate, ie. But many are 4-merous.
Stamens are the most conspicuous part of the flower.
They vary greatly in number, their number and occasional adhesion provide distinctive tribal characteristics and are important in identification. Wattles are recognised by the globes or pipecleaner- shaped clusters of yellow or golden stamens but it is not generally known that the flowers have tiny petals and few people have looked closely enough to see them. Separate a single flower and examine around the base with a 10x lens. The petals can then be clearly seen. Filaments are free, long and slender and crowned by small bilocular anthers which open by longitudinal slits to discharge pollen contained within.
