Detailed description
Perennial herb with stout branched stock producing one or more loose rosettes. Leaves spathulate, 30-140 × 3-14 mm, tip subacute, petiole longer than lamina; hairs alike on both surfaces, short, stiff, straight, closely appressed, barely overlapping, rather sparser on undersurface, clinging to margin. Lateral branches few, ascending or erect, sometimes again branched, 80-300 mm long, internodes equal in length to leaves. Uppermost stem-leaves 10-20 × 2-5 mm, narrow-oblong, sessile, tip acuminate-acute; hairs as on rosette-leaves but more crowded. Cymes ebracteate, on long leafless peduncles, simple or once (occasionally twice) forked; internodes between lower flowers becoming greater than calyx length; pedicels occasionally up to 5 mm long. Calyx c.4mm long, lobes greater than half calyx length, very narrow, acute; hairs usually all short, straight, stiff and appressed as on rest of plant, very crowded at base, evenly covering lobes. Corolla white (rarely pale yellow), c. 7-10 mm diameter, tube 7-8 mm long, narrow-funnelform, inconspicuous scales below mouth, lobes c.3 × 3 mm; filaments very short, fixed below (occasionally much below) scales, anthers 1·5 mm long, tips at or below level of scales; style much greater than calyx; stigma capitate. Nutlet 1.8-3.3 × 1.0-1.9 mm, ovate, black
Similar taxa
Myosotis goyenii is easily recognised by the ashen grey colouration, loose rosette-forming growth habit, grey long-petioled leaves and leaf hairs which overlap but do not obscure the epidermis.
Distribution
Endemic. South Island: South Canterbury and Central Otago.
Habitat
Dry bare banks, rocky steep slopes
Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2022-2023 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes replaces all previous NZTCS lists for vascular plants. Previous assessments can be found here.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – these interim threat classification statuses has not been assessed by the NZTCS panel.

Threats
Myosotis goyenii is a naturally uncommon species confined to a small part of the South Island. Within its range the species is rarely common - a pattern that is not that unusual for the New Zealand members of the genus. Despite this natural scarcity, as far as is known there are no active threats affecting this species.
