The spikes are in diameter and long with 18 to 60 individual flowers. The petals are long and fall off as the flower ages and there are 34-63 stamens in each flower. Flowering occurs from November to December, sometimes in other months and is followed by fruit that are woody capsules, long. Callistemon macropunctatus
