Current conservation status
The threat classification 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) – more information about this can be found on the NZTCS website 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. Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – a suggested threat classification status has not been assessed by the NZTCS panel.

Endemic. North Island: Kaimanawa and Ruahine Ranges
Subalpine to alpine. A basicole confined to limestone bluffs and talus slopes
Tufted somewhat spreading perenial herb with a much branched base bearing numerous loose rosettes. Rosette-leaves 8, up to 100 × 15 mm (in dwarfed plants only 10 × 2 mm), petiole slender, almost equal in length to lamina, broadly sheathing at base; lamina elliptic, tip apiculate; hairs short, straight, stiff, closely appressed, not overlapping and sparse on leaf undersides (sometimes almost absent on old leaves). Lateral branches ascending, up to 250 mm long, leafless below cyme, lower internodes us. < lvs. Stem-lvs up to 25×7 mm., elliptic, apiculate, sessile, hairs similar to those on rosette-lvs but a little longer. Cymes simple or forked, ebracteate, c.12-flowered, up to 30 mm long; internodes < calyx in fruit; pedicels up to 2-4 mm; calyx 5-6 mm long, lobes > half calyx length, narrow and acute, hairs short, stiff, sparse and appressed. Corolla white, 14-18 mm diameter, tube 4.0-4.6 mm long with vertically elongated scales at mouth, flaring above into wide funnel-shape with shallow lobes c.5.0-6.0 × 3.0-3.5 mm; filaments long, reaching to level of lobes; anthers 2 mm long, prominently exserted; style 2-3× calyx in fruit, stigma capitate. Nutlet 2.3-3.1 × 1.4-1.8 mm, ovate-elliptic, black.
Myosotis eximia is easily recognised by its much branched spreading habit; leaves which are sparsely hairy (with the hairs short, stuff, and closely appressed); by the large and dense fruiting inflorescences whose internodes are less than the length of the calyx; by the anthers which are much shorter than their filaments and by the large white flowers which have wide-funnelform corolla-tubes, and straight rather than hooked calyx hairs. In the wild part of its range Myosotis eximia is very unlikely to be confused with any other Myosotis species.
December - January
February - April
One of the few indigenous alpine Myosotis that is easily cultivated. Best grown in a sunny situation within a free-draining but moist soil enriched with lime. Excellent in a rockery or alpine house. This species flowers freely even in warm climates
Myosotis eximia is a narrow-range, naturally uncommon endemic confined to base-rich rocks (mostly limestone and calcareous sandstones) of the Kaimanawa and Ruahine Range. Although it is very localised species known populations seem secure and none appear to be threatened.
eximia: Strikingly unusual
Where To Buy
Myosotis eximia is occasionally sold by specialist native plant nurseries (and even from time to time in more general nursery outlets).
