Melaleuca zeteticorum

Melaleuca zeteticorum is a shrub in the myrtle family Myrtaceae and is endemic to the south-west of Western Australia. It is a shrub with narrow leaves and pale to bright yellow flowers in spring. Its species name zeteticorum was given "in honour of these persons who for their enjoyment explore natural vegetation communities to become familiar with their constituent species".

Description

The flowers are arranged in heads 28 mm in diameter near the ends of the branches in five to thirteen groups of three flowers. The flowers are bright yellow, pale lemon-yellow or whitish, turning pink with age. The stamens are arranged in bundles of five around the flower, with three to six stamens in each bundle. The base of the flower is 0.8-1.2 mm long. Flowering occurs in October and November and is followed by fruit which are woody capsules closely packed together, appearing like a single fruit.
