Conservation status of New Zealand indigenous vascular plants, 2012
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2012 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2009 and replaces all previous NZTCS lists for vascular plants. Authors: Peter J. de Lange, Jeremy R. Rolfe, Paul D.

Features

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.

Flowering

October - January

Flower Colours

White,Yellow

Fruiting

December - March

Propagation Technique

Difficult. Best grown in a rock garden or put, planted within a free draining, fertile soil (enriched with lime). The soil should be kept moist (never fully drying out) but not saturated. Does best in partial shade rather than full sun.

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.
