Distribution

Endemic. South Island: Kahurangi National Park (Mt Owen Massif). There is also some suggestion that this species may be present on Mt Arthur

Habitat

Subalpine to alpine on marble bluffs, boulders and talus.

Features

Stout, tufted, perennial herb. Rosette-leaves 50-110 × 7-11 mm, narrowly elliptic-spathulate, petiole slender and almost equal to lamina in length, tip subacute; hairs very finely silky, appressed, ± overlapping on upper surface, on undersurface similar but regularly retrorse. Lateral branches ascending to erect, 150-200 mm long, leafless below cyme, lower internodes < leaves. Stem-leaves c.25 × 7 mm, lanceolate with rounded base and narrowing to subacute tip, sessile; hairs similar to those on rosette-leaves but less closely appressed, on undersurface many retrorse especially on lower leaves. Cymes usually forked, ebracteate, many-flowered, 10-20 mm long or more, internodes very short, pedicels up to 6 mm long. Calyx 5-8 mm long, lobes cut to about half of calyx length, ± oblong and obtuse, hairs crowded, silky, appressed, ± flexuous but not hooked, many retrorse at base. Flowers scented. Corolla yellow, c.9-12 mm diameter, tube cylindric to above calyx, c.6 mm long, flaring slightly at mouth, scales prominent, lobes spreading, up to 4 mm long, ± oblong; filaments long and conspicuous, standing well above corolla, anthers c.1·5 mm long, versatile; style > stamens, stigma capitate. Nutlets 2.4-2.9 × 1.3-1.7 mm, ovate, dark black.

Similar Taxa

Myosotis concinna is a well marked species easily recognised by its stout growth habit, erect and rather tall many flowered inflorescence's which bear numerous large yellow flowers whose stamen filaments are unusually long and conspicuous, and which are clearly much larger than the anthers. It is unlikely to be confused with any other species.
