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.

Endemic. New Zealand: Campbell Island
Coastal to alpine. Low forest, Chionochloa antarctica tussocklands and Poa litorosa grasslands, also present in Marsippospermum gracile sedgeland on summit fellfields
Plants monocarpic, probably biennial, height in flower 16–220 mm. Caudex unbranched, 4–13 mm long. Root unbranched, c. 2 mm diam. At stem base. Flowering stems terminal only, largest flowering stem c. 2.5 mm diameter at base, stem colour green or tinted crimson, flowering stem leaves 4 pairs per stem, lowest pedicels from halfway up flowering stem. Rosette of leaves distinct from flowering stem leaves, narrowly elliptic, 11.0–82.0 × 3.1–17.6 mm, green or tinted purple-black or bronze, flat, apex acute to rounded, not recurved or recurved at tips of smaller leaves; margins recurved, thickened; petiole absent or indistinct, c.5–11 mm long, 1.6–8.8 mm wide at leaf base. Flowering stem leaves almost identical to rosette leaves but shorter and wider. Pedicels one or two per leaf axil, 1.6–4.5 mm long, c.0.5 mm diameter. Flowers 9–49 per plant, 7–12 mm long. Calyx 5.5–7.6 mm long, hairs at calyx–corolla fusion line present; lobes 4.0–5.9 mm long, 1.2–1.5 mm wide at base, plane, apices acute, margins minutely denticulate, sinus hairs sparse or absent. Corolla 9.5–14.0 mm long, white or coloured pink to dark purple with veins colourless or pink to dark purple; tube 3.0–5.5 mm long; lobes 4.6–8.5 × 1.5–2.9 mm, hairs below sinus absent; nectary 1.6–3.4 mm from corolla base. Filaments 3.4–7.2 mm long from corolla base, 0.5–0.6 mm wide. Anthers 1.0–1.2 mm long, anther wall blue-black, rarely yellow, extrorse at anthesis. Stigma colour unknown. Ovules 7–27 per ovary. Capsule 8.0–13.2 mm long.
Distinguished from all other New Zealand species by the combination of its erect terminal flowering stem, its flowers on short pedicels, leaves with a thickened and recurved margin, corolla and calyx hairs absent from the sinuses, nectaries distant from the corolla base, and corolla lobes narrow and long.
December – April
March - May
Difficult. Should not be removed from the wild.
A Naturally Uncommon, range-restricted, island endemic. Abundant on the islands it is under no obvious threat. The Campbell Islands are administered as a Nature Reserve and are part of a World Heritage Park with access strictly controlled by the New Zealand Department of Conservation.
