Discaria toumatou, Matagouri, is a plant endemic to New Zealand. An alternative but disused name for the plant is Wild Irishman. The name matagouri is how speakers of English heard the South Island pronunciation of the Māori name "matakoura". Matagouri is a tangle branched, extremely thorny shrub or small tree up to five metres tall. It has small leathery leaves close to the thorns, which are only abundant in spring, or the shade. The flowers are tiny and white with no petals.
