Vascular – Native
Dicotyledonous Herbs other than Composites
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.

Leaves numerous, narrow-spathulate, 30 x 30 mm, apex sub acute, all parts covered in silky silvery-white hairs all of one type, uniformly stiff, straight, appressed, imbricating so as to hide leaf surface entirely. Lateral branches few, erect, up to 150 mm. Stem leaves sparse, upper ones sessile, narrow-oblong, 6 x 2 mm, apex sub acute. Inflorescence a simple, terminal cyme. Calyx 3 mm long, lobes > half length, narrow, acute. Corolla yellow, 5 mm diam., tube 4-5 mm, flaring toward top, corolla lobes 2.5 x 1.5 mm, oblong, filaments short, anther-tips below to just above scales; style » calyx in fruit,. Nutlets ovate, pointed and keeled, 1.7-2.1 x 1-1.1 mm long.

Difficult. Should not be removed from the wild.
As far as is known this species has always been confined to a small portion of the Dunstan Range above the Kawarau River, near Cromwell. At present just the one population is known (and in fact this may be the same population as that discovered originally by John Buchanan and James Hector). That population has been regularly monitored for the greater part of 30 years, and seems to be stable. Nevertheless because the species is known from just the one site, within an area of < 1 ha it qualifies as Nationally Critical.
Where To Buy
A few plants are held by specialist growers. Very difficult to maintain in cultivation.
