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.

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.

Sprawling yellowish small-leaved shrub inhabiting coastal areas. Twigs orange, slightly fuzzy at tip. Leaves narrow, small, with dark line down middle on the underside, in clusters of pairs scattered along twigs. Flowers tiny, with long protruding threads. Fruit white.
Endemic. North, South, Stewart and Chatham Islands
Fleshy drupes are dispersed by frugivory (Thorsen et al., 2009).
Not Threatened but rapidly becoming scarce in large parts of its range. Seems to resent dune reclaimation and competition from marram grass (Ammophila arenaria).
coprosma: From the Greek kopros ‘dung’ and osme ‘smell’, referring to the foul smell of the species, literally ‘dung smell’
acerosa: From the Latin acus ‘sharp’, meaning sharp or pointed
