Common Broom

Botanical name:  Carmichaelia australis
Maori Name:   Makaka 
Common name:  Common broom
Height:  10 metres


North Island BroomCommon broom is a colonising plant that is found in coastal and lowland forest throughout the North Island and the South Island except for the far south. It can appear as a shrub or small tree up to 5m tall.Broom's flattened green stems and branches,described as phylloclades,act as leaves in mature plants. Tiny shamrock like leaves can sometimes be seen on young plants or even on plants which are growing in shade.

In mid November tiny white flowers flecked with purple veins appear. This gives them a pale lilac hue. By early December lots of small green pods form. Broom belongs in the legume family, Fabaceae. As the pods mature and ripen their sides fall away exposing small reddish coloured seeds sitting in individual 'jewel cases'.

The genus is named after Captain Dugald Carmichael (1772-1827) a Scottish army surgeon who botanised in South Africa, India and N.Z. Carmichaelia contains 24 species, all confined to N.Z.except for Carmichaelia exsul, which is found on Lord Howe Island (exsul is Latin for exile).
