Conservation status of New Zealand indigenous vascular plants, 2012
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2012 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2009 and replaces all previous NZTCS lists for vascular plants. Authors: Peter J. de Lange, Jeremy R. Rolfe, Paul D.

Synonyms
Coprosma acerosa f. brunnea Kirk
Distribution
Endemic. South Island only where mainly eastern.
Habitat
A species of inland river beds, moraines, and less commonly gravel and cobble beaches
Flower Colours
Yellow
Propagation Technique
Easy from fresh seed, semi-hardwood cuttings and rooted pieces. Prefers free draining soil in a sunny position. Most nursery stock sold over the last few decades as this species is not C. brunnea but an allied segregate of C. acerosa endemic to the Central Volcanic Plateau of the North Island.
Threats
Not Threatened. However, it ican be uncommon ove rlarge parts of its range, and is often heavily browsed by rabbits and hares.

Where To Buy
Occasionally offered by retail plant and specialist native plant nurseries.
Notes on taxonomy
Coprosma brunnea is part of the C. acerosa A.Cunn. complex, and many botanists prefer to regard it as either C. acerosa or a form of it. However, C. brunnea has been found growing sympatrically with C. acerosa, and remaining distinct from it, while nrDNA ITS and ETS sequences show that C. acerosa is a complex aggregate of at least 6 lineages (C. brunnea is one of these), and there are subtle morphological characters to support these lineages. Therefore until further research is conducted into this problem NZPCN think it better to retain C. brunnea at the rank of species.
