Аристотелия пильчатая: описание и особенности новозеландского макомако.

Species of plant

Aristotelia serrata, commonly known as wineberry or in the Māori language makomako or just mako, is a small tree in the family Elaeocarpaceae, in the genus Aristotelia, found in the North Island, South Island and Stewart Island of New Zealand. It is a small deciduous fast growing tree or shrub. The tree can reach up to 10m tall, with a trunk diameter up to 30 cm. The bark is pale brown, smooth and patterned with flat lenticels. Branches are long, slender and spreading, branchlets have a reddish brown colour when pubescent. First described by botanists Georg and Johann Foster in 1776 as Dicera serrata, Walter Oliver gave its current binomial name in 1921. Wineberry grows in association with many plants and provides a key food source for the Kererū. Flowering occurs in the spring, with berries ripening in summer.

Aristotelia serrata leaves have distinguishable traits. Leaves are thin, deeply and sharply serrated, light or dark green on adaxial surface, often pinkish green on abaxial surface, veins distinct on both surfaces, size between 5 12 x 4–8 cm. The leaves, are disposed in opposite or subopposite pairs. They have drawn out, pointed tips and prominent veins forming an obvious net like vein pattern on both sides. The margins are strikingly toothed, with larger, narrowly pointed, irregular, jagged teeth bearing smaller teeth. Some trees have red purple twigs and leaf undersides; others are just green. The leaves have long stalks, and each leaf stalk has a pair of small, narrow stipules, sometimes a few teeth, at its base. In the axils of the leafstalks are pointed buds, which can grow out into leafy shots or inflorescences. Flowers occur in an inflorescence of numerous cymes, flowers of all shades intermixed, coloured in cream through pink to dark red. Flowers has 4 to 6 mm diam; petals 3 lobed; stigma with 3 4 lobes; stamens numerous, arising from a glandular disc. The flowers are very numerous, in much branched clusters. They have petals with rounded, incised lobes at the ends and look like small versions of Elaeocarpus flowers. They are almost colourless when they open; then they change to pink, red, and dark red, providing a colourful display. Wineberry has male and female flowers on different plants, with some bisexual flowers among the males. The fruit is a berry that is 4 5mm in diameter, black, containing 8 angular seeds. It was given its current binomial name Aristotelia serrata by Walter Oliver in a 1921 article, who argued it was the name used to describe it most. Aristotelia is after Aristotle and the specific epithet serrata is latin for saw toothed.

Endemic to New Zealand, Wineberry can also be found on Stewart Island. Taking advantage of ecological disturbances such as natural tree falls A. serrata is plentiful in regenerating forest and damp river margins. As the flowers of the Wineberry mature they turn from white to red, there are both female and male flowers on different plants with some bisexual flowers among the males. Kererū are known to feed on the fruit of wineberry. In order to conserve kererū populations it is suggested by the Department of Conservation that wineberry be planted as a food source. The berries of the wineberry are not the only parts eaten: kawakawa looper (Cleora scriptaria) larvae can be found feeding on its leaves.

Aristotelia serrata has a multitude of uses by both European settlers and Māori. Māori used makomako medicinally by boiling its leaves as an application to burns and infected wounds. The berries serve as food and are often eaten by children, and can be squeezed to make a thick sweet drink. Wineberry can be used in a variety of way to create dyes: the plant contains tannins, and the bark can provide a blue black dye. European settlers burnt the shoots of the wineberry, changing the wood to charcoal for the production of gunpowder.
