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. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley.

Distribution
Endemic. North, South, Stewart and Campbell Islands. From Mt. Hikurangi south through the main axial ranges to Fiordland, also on Banks Peninsula on the high points of Stewart Island. Evidently very uncommon on Campbell Island.
Habitat
Subalpine to alpine. Usually on stabile scree, fellfield, stony ground and at the bases of rock tors in places subject to frequent immersion
Features
Decumbent, annual or rarely short-lived perennial herb, forming small circular patches on open ground. Rosette-leaves 15 × 5 mm long (sometimes more), lamina obovate or broadly spathulate, obtuse, petiole broad; upper surface hairy except towards base, undersurface almost or quite glabrous, hairs of upper leaf surface tapering to soft ± flexuous tips; spreading Lateral branches up to 8, decumbent, 30-150 mm long, usually branched, internodes usually less than leaves. Stem-leaves similar to rosette-leaves near base, becoming sessile above, bracts ovate to broad-oblong, distichous, exceeding internodes, diminishing in size, the lowest up to 10 × 5 mm. Cymes usually simple, few- to many-flowered, bracteate throughout; internodes usually less than bracts, sometimes very short; pedicels much smaller than calyx, very hairy. Calyx 3-5 mm long, usually lobed to halfway, lobes subacute; hairs long and ± retrorse short, not stiff or hooked. Corolla 3.0 mm diameter, cream to lemon-coloured, tube 2-3 mm long, cylindric, lobes narrow with obtuse tip; filaments very short, anthers < 1 mm long, wholly included, tips occasionally reaching level of scales; style less than calyx in length, stigma capitate. Nutlet 1.1-1.7 × 0.8-1.0 mm, ovate to ovate-elliptic, black, usually well immersed within calyx remnant.
Flowering
November - February
Flower colours
Cream, Yellow
Fruiting
December - April
Propagation technique
Easily grown from fresh seed. However, plants are short-lived and prone to fungal diseases in humid climates.
Threats
Not Threatened. However like most indigenous Myosotis this species is not that common either. There are no known threats facing the species.
Etymology
myosotis: Mouse-eared
drucei: After A.P. Druce, one of New Zealand’s most respected field botanists
Where To Buy
Not commercially available.
