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.

Brief description
Large shrub with pairs of thin wavy, mottled leaves. Leaves to 20cm long, oval, pointed, with small pits at junction of veins. Sharp dark point on stem between pairs of leaves. Fruit prange to red, on obvious stalks in open clusters.
Distribution
Endemic. North to South Islands. In the South Island extending to Lake Ianthe in the west and the Marlborough Sounds in the east.
Habitat
Common in the understorey of forest, and in sheltered shady sites from the coast to montane and cloud forest. In areas of high rainfall can be a major component of shrublands, and within regenerating forest. Often common along the margins of logging tracks and roads.
Wetland plant indicator status rating
Information derived from the revised national wetland plant list prepared to assist councils in delineating and monitoring wetlands (Clarkson et al., 2021 Manaaki Whenua – Landcare Research Contract Report LC3975 for Hawke’s Bay Regional Council). The national plant list categorises plants by the extent to which they are found in wetlands and not ‘drylands’. The indicator status ratings are OBL (obligate wetland), FACW (facultative wetland), FAC (facultative), FACU (facultative upland), and UPL (obligate upland).
FACU: Facultative Upland
Occasionally is a hydrophyte but usually occurs in uplands (non-wetlands).
Features
Shrub or small tree up to c. 6 m tall; plants much branched from base or with single trunk; branches and branchlets glabrous, smooth, under bark green. Interpetiolar stipules conspicuous, broadly deltoid, then tapering, apex with 2 porminent darkly pigmented denticles, glabrous. Leaves on smooth glabrous petioles 20-30 mm long; Lamina (100-)150-300 × (50-)70-100 mm, broadly elliptic to obovate, apex subacute or apiculate, base gradually narrowed to petiole; membranous to sub-coriaceous, adaxially dull glossy green or green mottled with maroon or purple, abaxially paler, margins flat or weakly undulose waved, rarely finely crenulate; venation prominent, reticulations conspicuous on both leaf surfaces, fine and close-set. Flowers in clusters on trichotomously branched peduncles up to 80 m. long. Male flowers with 4-5-toothed cupular calyx; corolla narrow-funnelform, lobes usually 5, acute, < tube; stamens us. 5. Female flowers usually with small stipulate bracts at axils of branches; calyx-teeth 5, small, acute; corolla tubular, lobes 5, narrow-triangular, acute, ± the same length as tube. Drupe reddish orange, oblong, 7-9 mm. long
Similar taxa
Easily distinguished by the very large, broad, yellow-green leaves which are variously mottled with dark green or purple, and have prominent leaf “drip-tips”, and by the very large, entirely glandular leaf stipules - seen otherwise only in the very different looking Coprosma waima. It also differs from all of the other similar large-leaved species by its usually autumnal flowering pattern.
Flowering
(March-) April (-June) but may also occasionally flower in September.
Flower colours
Green, White
Fruiting
(September-) October-January (-April)
Propagation technique
Very easy from fresh seed. Also easy from semi-hardwood cuttings. Prefers a shaded site in damp soil but will tolerate most garden situations.
Etymology
coprosma: From the Greek kopros ‘dung’ and osme ‘smell’, referring to the foul smell of the species, literally ‘dung smell’
autumnalis: Autumn flowering
Taxonomic Notes
For at least the last 30 years this Coprosma was known in New Zealand by the name Coprosma grandifolia. Recently Large et al. (2020) have shown that Coprosma grandifolia is an superfluous name for C. lucida J.R.Forst. et G.Forst. because it includes the type of Ronabea australis A. Rich. (Coprosma australis (A.Rich.) B.L.Rob.), necessitating the reinstatement of Coprosma autumnalis Colenso for the plant known to iwi as kanono.
