Its bark is white, and the twigs are finely hairy. The leaves are variously shaped, fleshy, bright green and from 10 to 70 mm long. The flowers are tiny and the fruit is white to pinkish.
=Habitat=
It is found in forest or scrub, on a wide range of hosts including tarata (Pittosporum eugenioides), karo (Pittosporum crassifolium), Coprosma species, putaputaweta (Carpodetus serratus), fivefinger (Pseudopanax arboreus), white maire (Nestegis lanceolata) and broom. According to De Lange et al., Tupeia antarctica parasitises some 48 hosts (11 exotic) with the most common host families being Fabaceae and Rubiaceae.{{Cite journal|last1=de Lange|first1=P.J.|last2=Norton|first2=D.A.|last3=Molloy|first3=B.P.J.|date=1995|title=An annotated checklist of New Zealand mistletoe (Loranthaceae) hosts|url=https://www.researchgate.net/publication/234131027|journal=New Zealand's Loranthaceous Mistletoes|pages=87|via=New Zealand Department of Conservation}}
Etymology
The genus is named for Tupaia (c. 1725 – 1770), a Tahitian navigator and priest.{{Cite web|url=http://nzpcn.org.nz/flora_details.aspx?ID=210|title=Tupeia antarctica {{!}} New Zealand Plant Conservation Network|website=nzpcn.org.nz|access-date=2020-01-05}}{{Cite book |last1=Lehnebach |first1=Carlos A. |url=https://www.wikidata.org/wiki/Q124332398 |title=Flora: Celebrating our Botanical World |last2=Regnault |first2=Claire |last3=Rice |first3=Rebecca |last4=Awa |first4=Isaac Te |last5=Yates |first5=Rachel A. |date=2023-11-01 |publisher=Te Papa Press |isbn=978-1-9911509-1-2 |language=English}} The specific epithet, antarctica, derives from the Latin word, anti, meaning "against" or "opposite" and the Greek word, arktos, meaning "bear", giving an adjective, antarctica, which meant opposite the constellations of the Ursus Major and Ursus Minor, "opposing the north", or "Antarctic".{{Cite web|url=http://www.plantillustrations.org/epithet.php?id_epithet=214961%3C/div%3E%3Cdiv%20class=|title=antarcticus,-a,-um|website=www.plantillustrations.org|access-date=2020-01-05}}
Taxonomy
Status
Tupeia antarctica is classified (2018) as having an "At Risk - Declining" conservation status under the New Zealand Threat Classification System, (its predicted decline from greater than 100 000 individuals being from 10 to 70%). A 2002 study discusses the threat from possum browsing which is preventing the recruitment of new individuals.
