Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley.

Rounded shrub to 1m wide growing on other trees with white bark, finely hairy rounded twigs (lens needed), fleshy variously-shaped bright green leaves and whiteish to pinkish fruit. Leaves 10-70mm long. Flowers tiny.
Endemic to the North and South Islands.
Forest or scrub (often in regenerating vegetation), where it is parasitic on a wide range of hosts including tarata, karo, Coprosma species, putaputaweta, fivefinger, white maire and broom.
A shrubby semi-parasite to 1 m diameter. Leaves are oppositely arranged, variable in shape, 10 to 70 by 10 to 40 mm, slightly fleshy and bright green. Stems are always rounded in cross section near the tips, have pale white to grey bark, and downy or hairy branchlets. Flowers are tiny, greenish-yellow. Fruit are fleshy, white to pink, 5 to 7 mm diameter.
Peraxilla colensoi, P. tetrapetala and Trilepidea adamsii all have colourful flowers. Ileostylus micranthus has tiny, yellow-green flowers, a ‘bent’ style, yellow fruit and young stems that are squarish in cross-section and have multiple attachments to its host. All these species are hairless.
Flowers from October to December.
Fruit appear from December to March.
Difficult. Has been grown successfully by some people but many others have failed. Best success is achieved with seed that has been sown fresh (within one to two days of harvesting) onto a suitable host.
Possum browse is the primary threat to this species. Insect browse, habitat destruction, loss of pollinating and seed-dispersing native birds, collectors, vandalism and fungal disease also threaten this species.
tupeia: Named after Tupaia (c. 1725 – December, 26 1770) who was a Tahitian Polynesian navigator and arioi (a kind of priest), originally from the island of Ra’iatea in the Pacific Islands (see Chamisso & Schlechtendal, 1828).
This species will on occasion extend into beech forest where it has been found parasitic on red mistletoe (Peraxilla tetrapetala). Favoured indigenous hosts include Pseudopanax arboreus, Carpodetus serratus, Nestegis cunninghamii, Pittosporum eugenoides, P. tenuifolium, and Coprosma spp. At present the species has been recorded from 48 hosts (11 exotic) spread through 32 genera and 20 families (de Lange et al. 1997), though this figure needs revision as since that time many more hosts have been reported.
