- Te Ao Māori
- Tātarāmoa appears throughout Māori tradition as the hooked thorn plant of the forest. The name captures both its armament and its tenacity. The fruit was eaten fresh or dried for later use. The thorny stems were sometimes used as crude fish hooks or as tools for dragging items from water. The plant's habit of catching clothing and skin was well known and often remarked upon in oral tradition. In modern contexts, bush lawyer remains a plant that commands respect. Walkers curse it. Conservationists appreciate its role in forest regeneration. Birds eat its fruit and spread its seeds. The thorns keep doing their job.
It hooks you. Bush lawyer. The name tells you everything you need to know. It holds you. And does not let go until you have paid some kind of price. The stems are long, arching, and armed with backward-facing thorns. Walk past one and it catches your sleeve. Try to pull away and it digs deeper. The thorns are not defensive in the usual sense. They are grappling hooks. The vine climbs by reaching up. Hooking onto branches. And pulling itself forward. Anything that brushes past becomes an accidental climbing aid.
The leaves are compound. Divided into three to five leaflets with toothed edges and a leathery texture. The undersides are pale, almost white. With soft hairs that give them a velvety feel. Nice to touch if you ignore the stem.
Flowers appear in spring. White, five-petalled, about two centimetres across. They look like wild roses but smaller. Bees work them. Beetles visit. The whole operation runs without much drama.
Then the fruit arrives. Red, glossy, a cluster of small drupelets that tastes like a raspberry but sharper. Tart. Complex. The kind of flavour that makes you pucker and then go back for more. Birds love them. So do people, if they can reach the fruit without bloodshed.
The vine scrambles over anything in its path. It does not care what it climbs. Fallen logs, standing trees, fence posts, other shrubs – all of them count as real estate. The thorns grip. The stems extend. The whole plant leans forward like it is late for something.
Getting through a patch of bush lawyer requires negotiation. You can go around. You can go under. You cannot go through without losing fabric, skin, or dignity. The plant does not intend harm. It just does not care about your comfort.
The fruit keeps ripening. The thorns keep hooking. And the vine keeps climbing.
