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 threat classification 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) – more information about this can be found on the NZTCS website 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. Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – a suggested threat classification status has not been assessed by the NZTCS panel.

Glossy shrub with strong-smelling, obvious, red, tubular drooping flowers. Leaves glossy, wavy.
Endemic. North Island throughout but absent from the central volcanic plateau where it is replaced by A. turneri. South Island, North-West Nelson only
Fleshy berries dispersed by fruigivory (Thorsen et al., 2009).
Can be grown from semi-hardwood cuttings though these strike with varying degrees of success. Seed is often hard to germinate. Layers readily. Prefers a semi-shaded site in a cool place with permanently damp soil. Slow growing and prone to sudden collapse during dry spells.
Although not considered nationally threatened this species is often heavily browsed by ungulates and possums, and rarely sets much viable seed, except where indigenous nectar feeding birds are common - such as on rodent-free offshore islands
alseuosmia: Perfume grove
macrophylla: Big leaf
