(Lygodium articulatum)
Lygodium articulatum, commonly referred to as mangemange or Bushman's mattress, is a fern endemic to the North Island forests of New Zealand. Mangemange is an endemic species and is unique compared to other ferns in the area due to the vine–like curtain it creates in the canopy. Although the majority of the plant is found in the canopy of the surrounding forest, the roots and stem of mangemange form on the ground, meaning it cannot be classified as an epiphyte.
