(Myrsine australis)

Myrsine australis, commonly known as māpou, red matipo, māpau, tīpau, and mataira, is a species of shrub within the family Myrsinaceae. It is endemic to New Zealand, found throughout both the mainland and offshore islands. Myrsine australis is a small shrub or tree, growing from 3–6 metres tall with short upright branches that create a compact crown. The trunk grows up to 20 cm in diameter, with the bark of the trunk and older branches a dark brown/black, whereas the juvenile branches are reddish, a distinguishing feature of this plant. The leaves are coloured pale green with a yellow tinge on the top surface, while the underside of the leaf is a paler version of this. Measuring 3–6 cm in length to 1.5-2.5 cm in width, the leaves are arranged alternatively on the stem and have a leathery texture. The leaf margins are normally wavy, however some uncommon forms may also have flat leaf margins. Each leaf blade is typically covered in round, translucent glands, and is connected to a red, approximately 5mm long, leaf stalk. These leaf stalks, also called petioles, can vary in colour and size as a result of environmental conditions and local population trends.
