Kunzea occidentalis is a flowering plant in the myrtle family, Myrtaceae and is endemic to a western New South Wales. It is a shrub with narrow leaves and small groups of white flowers on leafy side-branches. It is distinguished from the similar Kunzea ambigua by the flanges on the sides of its young branches.
Kunzea occidentalis is a shrub which usually grows to a height of NaNsigfig=1NaNsigfig=1 with its young branches having its leaf bases as raised, spongy, cream-coloured tissue. The leaves are arranged alternately, linear to narrow lance-shaped, NaNsigfig=1NaNsigfig=1 long and about 1sigfig=1NaNsigfig=1 wide with a petiole usually less than 1sigfig=1NaNsigfig=1 long. The flowers are arranged singly or in groups of up to six near the ends of the branches. There are egg-shaped to elliptic bracts about 2sigfig=1NaNsigfig=1 long and 1sigfig=1NaNsigfig=1 wide and smaller paired bracteoles at the base of the flowers. The floral cup is glabrous and NaNsigfig=1NaNsigfig=1 long with the sepal lobes NaNsigfig=1NaNsigfig=1 long and glabrous. The petals are white, broadly egg-shaped to almost round and about NaNsigfig=1NaNsigfig=1 long. There are about 50-60 stamens which are NaNsigfig=1NaNsigfig=1 long. Flowering occurs in October and November.[1] [2]
Kunzea occidentalis was first formally described in 2016 by Hellmut R. Toelken and the description was published in Journal of the Adelaide Botanic Garden.[3] The specific epithet (occidentalis) is a Latin word meaning "western"[4] referring to the distribution of this species on the western side of the Great Dividing Range.
This kunzea grows in heath and forest, mainly in rocky places and in creek beds. It is found on the western slopes of the Great Dividing Range and is common in the Warrumbungle and Mount Kaputar national parks.
