Leaves are divided. Not once or twice. But seven times, creating a palmate shape that resembles fingers. The seven finger grows in lowland to montane forests where light filters green through dense canopy. Its colouration is dark green, blending with surrounding foliage. This cryptic appearance helps it avoid detection by herbivores.
Patē. The Māori name refers to this common forest shrub. Early Māori used the wood for tools and fuel, though its softness made it less desirable than harder woods. The bark was used for medicinal purposes. Today the seven finger serves as an indicator of forest health. Its presence signals intact lowland forests and suitable moisture levels. Conservation efforts focus on protecting remaining populations from possum browsing and habitat loss.
The species inhabits lowland to montane forests throughout the North and South Islands. It prefers moist well-drained sites with high humidity, thriving where rainfall is consistent. Unlike canopy trees, it often grows as an understory shrub. Adults reach up to 7 metres in height, forming a dense canopy that shades the forest floor. Their shallow root systems anchor them in fertile soil, allowing survival in competitive environments.
Diet consists of nutrients obtained through photosynthesis and mycorrhizal exchange with soil fungi. The plant does not consume organic matter directly but rather extracts minerals and water from surrounding substrate. This symbiotic relationship allows it to thrive in nutrient-rich lowland soils where competition is moderate.
Breeding occurs via bird-pollinated flowers that produce vast quantities of nectar. Seeds are small and dispersed by birds to new locations. Germination requires bare mineral soil, explaining the plant's preference for disturbed sites like treefalls and landslides. Seedlings grow moderately fast, taking years to reach maturity.
Classified as Not Threatened, seven finger remains widespread throughout New Zealand. Populations are stable in suitable forest habitat. However possum browsing remains the primary threat. Habitat loss from logging compounds pressure on remaining populations. Conservation efforts focus on possum control and protecting remaining old-growth forests. Each surviving plant represents a legacy of ancient forests. The seven finger persists where protection is maintained, a testament to resilience in a changed world.
