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.

Cordyline indivisa (Forst.f.) Steud.
Palm-like small upland tree with few erect branches that have tufts of tough long wide pointed blueish-green leaves. Leaves 1-2m long by 10-15cm wide, usually erect, dead leaves forming a skirt at base of tuft, central vein reddish at base. Fruit small, blueish.

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.

Endemic. In the North Island known south of Kohukohunui (Hunua) and Te Moehau (Coromandel Peninsula) but only really common from the Raukumara Ranges and northern portion of the Central Volcanic Plateau southwards. In the South Island widespread and common along the north and western portions of the island, more local in the drier eastern regions.
A feature of montane forests and subalpine shrublands (where it usually grows within gullies and at valley heads). Extending into lowland situations where physical geography allows for a cooler climate. The characteristic cabbage tree of the wetter, montane forests of the West Coast of the South Island.
Stout tree up to 8 m tall. Trunk up 0.4-0.8 m diam. Stems massive, usually unbranched or sparingly so. Leaves 1-2 x 0.1-0.15(-0.3) m, blue-green above, glaucous below, broadly sword-shaped, drooping with age, narrowed above base to a short petiole, midrib stout, broad and conspicuous, often tinged red, orange red or golden. Inflorescence a panicle arising from base of growing points under leaves. Peduncle stout, fleshy, short and more or less hidden in foliage. Panicle 0.6-1.6 x 0.3 m, very compact, with only first order branching from stout central axis. Basal bracts broad. Racemes 100-200 mm long, 20 mm diam. Flowers somewhat fleshy, faintly fragrant, crowded on axes. Pedicels obvious, 2-3(-5) mm long. Perianth 7-8 mm long, tepals fused for most of length, strongly recurved. Stamens more or less equal to tepal length. Stigma narrow-capitate. Fruit 6 mm dim., globose bluish to dark blue. Seeds 2 mm long, black, shining, 2 sides flat and one convex.
A very distinctive species immediately separated from all other Cordyline species by the very broad blue-grey leaves, and smaller, tightly, compacted inflorescence produced at the base of the foliage tufts.
Easily grown from seed. However this species requires cool, damp soils and shady or cool situations, unless grown within the montane habitats it prefers. In lowland, warm climate situations few plants ever reach flowering size before dying.
Not Threatened. However, some northerly populations have been decimated by goats, and it is presumed extinct on Te Moehau as a result of goat and livestock browse. The sudden death of some specimens in cultivation and in the wild has been attributed to Sudden Decline but it is still not clear if this species really does survive from this syndrome.

Life Cycle and Dispersal
Fleshy berries are dispersed by frugivory (Thorsen et al., 2009).
Where To Buy
Rarely cultivated. Occasionally offered by garden centres and specialist native plant nurseries. A very attractive species which is prone to sudden collapse during high temperatures or in times of water stress. Does best in cool, damp soils, in semi-shade. Easily cultivated in the cooler parts of the country. It can be grown with great difficulty in lowland situations from Hamilton north but few plants ever survive to flowering size.
