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.

Brief description
Small shrub consisting of a tuft of long very narrow leaves and often without a visible trunk. Easiest to identify by the long sparse sprays of small white or pink flowers developing into a blueish fruit. Leaves to 1m long x 1-2cm at widest, tapering into a grooved leaf stalk.
Distribution
Endemic. North Island from Te Paki (North Cape) to Kawhia Harbour in the west and Bay of Plenty in the East.
Habitat
Coastal to montane. Often in gumland and other shrubland. Common in kauri (Agathis australis) forest, especially along ridgelines and around slip scars.
Features
Plant forming leafy tufts up to 1 m tall, trunk usually absent, rarely sparingly developed, occasionally reaching up to 2 m tall. Plants often flowering while short stem is leafy to ground; in older plants bare part of stem up to 0.1 × 0.15 mm and usually sprawling, rarely stiffly erect. Leaves 0.30–0.60–1.00(-1.30) × 0.01–0.02 m, yellow-green to green (sometimes red-spotted) ± narrowed above base into channelled petiole; midrib prominent abaxially, at least proximally; margin slightly recurved. Inflorescence an openly, sparingly branched panicle up 0.1 × 0.8 m, axes slender branched to second order;bracts often small and inconspicuous; ultimate racemes 50–300 mm long, axis clearly visible between flowers. Peduncle to 100 × 3–4 mm. Flowers small, widely spaced; pedicels 3-5(-10) mm long, Perianth c.4–5 mm long, whitish, or pink externally; tepals narrow, recurved, 3-nerved. Stigma shortly trifid. Fruit c.4–5 mm diameter, globose, bluish or flecked with blue. Seeds c.2.0–2.5 mm. long, shining, two sides flat and one convex. Description adapted from Moore & Edgar (1970).
Similar taxa
Easily distinguished from all other Cordyline in New Zealand by its usually “stemless” growth habit (the stems are actually buried beneath the soil). More frequently confused with Dianella or Libertia from which it is easily distinguished by the, yellow-green, prominently ribbed leaves and much larger, lax paniculate inflorescences, and small, globular bluish to white flecked fruits.
Flowering
October - January
Flower colours
Red/Pink, White
Fruiting
March - May
Life cycle
Fleshy berries are dispersed by frugivory (Thorsen et al., 2009).
Propagation technique
Easily grown from fresh seed and stem cuttings. Does well in full sun in a well drained soil. It an excellent plant for a raised garden or for pot culture on for example a deck. A purple-leaved form of Corydline pumilio is now very popular in cultivation.
Etymology
