NVS Species Code

TUPANT

The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.

Structural Class

Dicotyledonous Trees & Shrubs

Synonyms

Viscum antarcticum G.Forst., V. pubigerum A.Cunn., Tupeia cunninghamii Miq. T. pubigera Miq.

Distribution

Endemic to the North and South Islands.

Habitat

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.

Features

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.

Similar Taxa

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.

Flowering

Flowers from October to December.

Flower Colours

Green,Yellow

Fruiting

Fruit appear from December to March.

Propagation Technique

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.

Threats

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.

Cultural Use/Importance

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, Nestegia 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, DoC, Wellington ISBN 0-478-01906-8), though this figure needs revision as since that time many more hosts have been reported.
