Myosotis uniflora

Myosotis plants are compacted cushions or mats that can reach 50 cm in diameter. The many imbricate rosette leaves have petioles 1–4 mm long that are glabrous but with erect hairs on the edges. The rosette leaf blades are 1–4 mm long by about 1 mm wide (length: width ratio 1.4–4.1: 1), lanceolate to ovate or triangular, widest at or below the middle, with an acute apex. The upper and lower surfaces of the leaf are sparsely to densely covered in long, flexuous, appressed to patent, antrorse (forward-facing) hairs that are oriented parallel to the mid vein. Each rosette has few prostrate to ascending, once-branched, bracteate inflorescences that are up to 60 mm long. The cauline leaves are similar to the rosette leaves but smaller. Each inflorescence has a solitary flower, borne on a short pedicel, with a bract. The calyx is 1–4 mm long at flowering and 2–5 mm long at fruiting, lobed to about half its length, and densely covered in long, antrorse, flexuous (rarely hooked at the calyx base), mostly appressed (few patent) hairs. The corolla is cream to yellow, 2–7 mm in diameter, with a cylindrical tube, petals that are obovate to very broadly obovate or ovate to very broadly ovate, and flat, and small yellow scales alternating with the petals. The anthers are usually fully included, or sometimes partially included with the tips only surpassing the scales. …

Myosotis uniflora is a forget-me-not endemic to the South Island of New Zealand in the ecological districts of Canterbury and Otago from 210–850 m ASL elevation. It is mainly found in Otago, but is also known from Westland, Canterbury and Fiordland from 1020–2130 m ASL. M. uniflora plants are found scattered throughout lowland river-bed flats and terraces, with other cushions, herbs and subshrubs. They are closely associated with cushionfield, moss-stonefield and stonefield plant communities in upper river catchments.
