Description

''Melaleuca serpentina'' is a shrub growing to tall with hard, papery bark. Its leaves are arranged alternately and are long, wide, more or less flat, narrow elliptical to egg-shaped with the narrow end towards the base and an end tapering to a sharp point. The leaves have a mid-vein but the lateral veins are obscure and there are many distinct oil glands. The flowers are creamy green to yellow and are arranged in spikes on the ends of branches that continue to grow after flowering and also in the leaf axils. The spikes are in diameter with 15 to 35 individual flowers. The petals are long and fall off as the flower ages and there are 37 to 51 stamens in each flower. Flowering occurs in April, October and December and is followed by fruit that are woody capsules, long. Melaleuca serpentina (habit)
