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 to Mt Peel near Geraldine, in the South Island.
An alpine species growing in stable soils within shaded fell-field, on ledges, and within soil-filled crevices.
Perennial evergreen alpine subshrub forming dense, compact cushions. Leafy stems numerous, forming erect branched rosettes, 15 × 15 mm, including leaves. Leaves alternate, sessile, spreading, , 8–10 × 3–4 mm, lanceolate, apex acuminate; margin entire, smooth; clothed on both surfaces with thin shinning, silvery-white, tightly appressed tomentum. Peduncles distinct, terminal on leafy stems, 20-40 mm, clothed in dense woolly silvery-white tomentum. Inflorescence 10–25 mm diameter, consisting of 3–6 capitula arranged in a flat to convex, congested, corymbose cluster packed with woolly crimped tomentum and surrounded by 10–15 spreading, lanceolate, acuminate, woolly, crimped leafy bracts, c. 10 × 4 mm, forming a pseudo-ray. Involucral bracts 2 or 3-seriate, papery, linear-lanceolate, c. 6 mm long. Receptacle flat or convex, nude. Outer florets filiform, ♀, 6–16, in 1 series; corolla yellow, c. 4 mm long, dilated towards apex, 4-lobed. Inner florets tubular, hermaphrodite, 18–45; corolla yellow, c. 4 mm long, dilated towards apex, 5-lobed. Style arms long, curved, truncate, slightly papillose at apex. Anthers yellow, sagittate at base, with short tails. Pappus in 1 series, c. 4 mm long, slightly shorter in filiform florets, flattened at base, scabrid and shining, thickened at tips. Achene spindleshaped, c. 1.5 mm long, obscurely angled; hairs many, 0.1–0.6 mm long.
A very distinctive species separated from the other three Leucogenes by the compact, cushion forming habit, silvery white leaves and octoploid chromosome number. A detailed account of this species and its relationships is provided by B.P.J. Molloy (N.Z.Jour.Bot. 33(1): 56-59 (1995))

Pappate cypselae are wind dispersed (Thorsen et al., 2009).
Difficult. Should not be removed from the wild.
A very localised species confined to the fell field of the summits of Middle and main ridge leading to Big Peel. Recent field work suggests that these populations are declining although the exact cause is unclear. The most significant losses have occurred on Middle Peel, where the Leucogenes was already considered to be very uncommon.
