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.

An ultramafic endemic confined to montane habitats where it grows in rock strewn ground amongst Chionochloa defracta tussock grassland and until recently at another site within a sparse kahikatoa (Leptospermum scoparium) shrubland
Dark reddish-green perennial herb. Rosette-leaves few, 20-50 × 5-9 mm, narrow-spathulate, apex acute, apiculate, basally attenuate, gradually tapering into winged petiole 10-45 mm long, followed by a broad sheathing base; hairs fine, silky, scarcely overlapping, appressed to spreading, distinctly retrorse on undersides, with the hairs of the leaf margins and sheathing leaf-base distinctly longer than those of the rest of the leaf. Lateral branches numerous, widely spreading, at first suberect, soon erect, up to 200 mm, internodes > leaves, with hairs fringing margins. Stem-leaves few, clearly distinct from rosette-leaves, c. 8 × 3 mm., narrow-oblong, sessile, acute; hairs fine and silky on upper surface, coarser and sparser on undersides, long and fringing on margin. Cymes simple, ebracteate, c.12-15-flowered, c.50-80 mm long; internodes> calyx in fruit; pedicels up to 4 mm long. Calyx 3-4 mm long, lobes > ½ length, narrow, subacute; hairs on lobes long, flexuous, basally in mixtures of shorter, appressed and longer hooked ones. Corolla white with a yellow eye, c.8-10 mm diameter, tube funnelform and c.5 mm long with scales set well above level of calyx-tips, lobes c.3.0 × 2.5 mm, ± oblong; filaments fixed about level of scales, > anthers and carrying them well above scales to level of lobes, anthers 1.1-1.3 mm long; style » calyx in fruit, stigma capitate. Nutlets ovoid, pale-brown.
An ultramafic endemic known only from one site on the Red Hills, above the Wairau River, Marlborough. In the field it is easily distinguished from the only other common reddish coloured forget-me-not present in that area Myosotis monroi. That species has yellow not white flowers borne on compact rather than elongated inflorescences, and the leaf hairs are sparse, uniformly short, stiff and closely appressed, rather than fine and silky, and retrorse on the leaf undersides.

Difficult. Should not be removed from the wild.
The only recently confirmed population occurs within habitat threatened to a degree through despoilation by 4-wheel drivers (this threat has been curbed to some extent by the erection of a vehicle barrier). Wilding pines are a major threat to the whole of the Red Hills. Potential threats include deer and goats though as yet there has been no evidence of browsing pressure on the Myosotis from these animals.
