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.

Found from sea level to 600 m a.s.l. in rocky places such as cliff faces, boulderfield and rock strewn ground, growing on thin peat soils and rock saprolite.
Perennial rosette-forming herb. Rosette usually single, sometimes several and so appearing tufted; rosette lamina linear-oblong to spathulate, 30-120 × 10-25 mm, apex rounded, ± mucronate, petiole very wide and ill-defined; lamina densely clad in long, silky hairs, spreading, upper surface hairs numerous, hairs of leaf undersides shorter and sparser, tending toward glabrescent or glabrate. Lateral branches erect, few to many, occasionally branched, 50-300 mm long, internodes < leaves. Stem-leaves many, ± recurved, upper ones sessile and oblong, up to 40 mm long, tip rounded and mucronate; hairs long, fine, spreading, crowded, especially on upper surface. Cymes ebracteate, except for an occasional leaf near base, 8-flowered, short and usually branched; internodes between fruits usually much < calyx except towards base; pedicels very short. Calyx 3-5 mm long, lobes > 1/2 length, rather broad, obtuse, nerve rather strong, hairs numerous, not hooked, silky, mostly long. Corolla deep blue, 4-8 mm diameter, tube 3-5 mm, cylindric, lobes broadly rounded (e.g. 2.0 × 2.5 mm.) and flat; filaments very short, anthers up to 1 mm long, acute, tips reaching to or just beyond scales; style > calyx in fruit, stigma capitate. Nutlets 1.2-2.5 × 1.2-1.5 mm, black, acute, keeled on inner face.
The uniformly dark blue pigmented flowers, bright green leaves and restriction to the Auckland and Campbell Island groups immediately distinguish this species from all other indigenous Myosotis spp. It could however be confused with the exotic M. sylvatica - which is commonly naturalised in New Zealand and not yet known from the Auckland and Campbell Islands. Myosotis sylvatica is much bigger than M. capitata, grows in a wider range of usually disturbed weedy habitats and the corolla-lobes of the flowers have a white base to them.
November to February
December to February
Difficult. Should not be removed from the wild. Can be grown from fresh seed but dislikes humidity and excessive heat. In cultivation even apparently healthy plants are often prone to sudden collapse.
Not threatened. Listed because it is a narrow range endemic of the Auckland and Campbell Islands. Some past reports suggest it is becoming less common on Campbell Island but these observations are countered by other reports suggesting that while sparsely distributed it is still common there. It is for this reason this species has been qualified Data Poor (DP).
capitata: From the Latin capitus ‘head’, with a knob-like head or tip
