Carmichaelia australis, commonly known as the New Zealand common broom or mākaka, is a shrub of the Fabaceae family. It is native to New Zealand and found in both the North and South Islands.

Description

New Zealand broom is a rapidly spreading and ascending shrub typically growing between 2-8 x 2-5 meters. Carmichaelia australis has distinguishing morphological structures allowing for easy identification due to the design of its stems, its flowers and colour formations. Its flattened photosynthetic cladode stems take in sunlight, and this plant has no need for leaves. However, three to five foliates can sometimes be present on seedlings and young plants. If leaves are present, they are vibrant green compound leaflets and at times have dark spots. Both the leaves and stems have smooth surfaces with minimal hairs. Each of the leaflets has a notch at the apex (tip of leaflet) which is emarginate.

The floral arrangement of C. australis on the main stem is raceme, with one to three of these short stalks per node, with each stalk having five to eight flowers. The outer floral green leaves on each flower are often bell shaped and triangular being pressed up against the middle flower petals. Flowers are often very small, having a white pigment and purple veins. Pollen and reproductive structures of the flowers of C. australis at the core with the stamens (male fertilizing organ) being 3-4 mm long and the pistil being 4 mm long (female fertilizing organ). The New Zealand Broom pods are oblong shaped with a grey, brown or black external appearance. These pods split open when mature to release seeds. In each pod there is between one and three seeds. These seeds are oblong, or bean shaped and vary in colour between orange, red and green, sometimes with black mottling.

The species was first described by Robert Brown in 1825. The specific epithet, australis, means "southern". The earliest collected specimen was collected by Joseph Banks and Daniel Solander in 1769 (AK102896) and is held in Auckland Museum.
