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. 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.

Indigenous: New Zealand: North Island (Coromandel Peninsula, Otama). Present also in Australia, Lord Howe and Norfolk Islands.
Mainly a strand line species of sandy beaches which occasionally colonises coastal headlands, or grows under coastal forest
Succulent, glabrous perennial. Stems prostrate, widely spreading, rooting at nodes. Leaves opposite, triquetrous, very succulent, basally connate, ensheathing stem, 30-100 × 8-15 mm, light-green, faintly glaucous, adaxial and lateral faces flat, lamina becoming convex toward base; keel crenulate in upper portion, otherwise smooth. Flowers solitary, terminal, 40-60 mm diameter. Pedicels 10-30 mm long. Sepals 5 with 2 larger than the others, triquetrous and opposite, smaller 3 with membranous margins. Petals numerous, magenta, white at base. Stamens 300-400, 5-6-seriate. Styles 7-10. Fruit fleshy, indehiscent, ellipsoidal, 20-30 mm long, reddish, edible, tasting of strawberries.
Differs from the other two naturalised species in New Zealand, C. chilensis and C. edulis by the glaucescent leaves, and smaller (40-60 mm diameter cf. 65-100 mm diameter) magenta rather than purple (C. chilensis) or yellow (C. edulis) flowers.

Fleshy capsules are dispersed by frugivory and possibly wind and water (Thorsen et al., 2009).
Easily grown from rooted pieces, fruits and by the division of established plants.
Carpobrotus glaucescens has been controlled as a weed species within its only known New Zealand locations. At the time this was done it had not been considered that it might be a natural, self-introduction. It is not known if it now survives in the wild in New Zealand.
carpobrotus: From the Greek karpos ‘fruit’ and brotus ‘edible’, the fruits of some species being edible.
glaucescens: Becoming glaucous
