Dactylanthus taylorii flower
Dactylanthus taylorii is the only fully parasitic flowering plant endemic to New Zealand. A member of the mainly tropical family Balanophoraceae, it lives mainly underground attached to the roots of a number of native tree and shrub species, where it forms a characteristic distortion on the host root in the area of attachment (the so-called woodrose). In autumn, each plant produces inflorescences filled with nectar which emeerge just above the forest floor. D. taylorii is dioecious, producing male and female inflorescences on different individuals. The endemic short-tailed bat (Mystacina tuberculata) is so far the only confirmed native pollinator. Mice and introduced ship- and Norway rats have been shown to be introduced pollinators, though rats often destroy flowers rather than pollinate.

Dactylanthus taylorii grows as a root parasite consisting mainly of a round warty rhizome up to 50 cm in diameter, attached to the root of a host tree or shrub. In response to dactylanthus the attached area of host root moulds itself into the shape of a fluted wooden rose (the woodrose). Dactylanthus obtains its nutrients from the host plant through this attachment. It has no green leaves or roots of its own. At this stage it is known to parasitise about 30 species of native trees and shrubs. Many of these host species are seral and found mainly on forest margins or disturbed areas. Mahoe, lemonwood, lancewood, kohuhu, wineberry, broadleaf, fivefinger, pate, karamu and putaputaweta are common hosts. It is not known from non-native species, gymnosperms or monocotyledons.

Dactylanthus prefers damp well-drained sites, and is never found on really dry sites.
