Myosotis goyenii subsp. goyenii

goyenii is a subspecies of flowering plant in the family Boraginaceae, endemic to southern South Island of New Zealand.

Plants of this subspecies of forget-me-not are perennial rosettes which form loose clumps, with ebracteate, erect inflorescences, and white corollas with partly exserted stamens.

[5][2] Multiple specimens of original material (syntypes) of Myosotis goyenii were collected in different localities in Otago, New Zealand by Peter Goyen (from Arrowtown) and Donald Petrie (from the Cardrona Valley and Lake Hawea).

The lectotype was designated by Carlos Lehnebach,[6] and is lodged at the herbarium of the Museum of New Zealand Te Papa Tongarewa (WELT SP002484).

infima by its clumps of single rosettes that have a central woody taproot, and the following floral characteristics: a long style (> 6 mm), pistil that is 1.6–2.8× longer than the calyx, filaments attached < 1 mm below the scales, and anthers only partly included (with the tips equal to or just surpassing the scales).

goyenii plants have long woody, branched taproots, and are single rosettes that often grow together to form loose clumps.

The rosette leaf blades are 7–40 mm long by 3–11 mm wide (length: width ratio 2.2–5.3: 1), usually narrowly oblanceolate, oblanceolate or narrowly obovate, widest at or above the middle (rarely below the middle), with an acute apex (rarely obtuse).

Both surfaces and the edges of the leaf are densely covered in straight, appressed, antrorse (forward-facing) hairs that are oriented parallel to the mid vein.

Each rosette has 2–40 erect, usually once-branched (sometimes unbranched), ebracteate inflorescences that are up to 350 mm long and are usually bifurcating in an open, forked 'V' shape near the tips.

[5] The species M. goyenii is listed as At Risk - Naturally Uncommon on the most recent assessment (2017-2018) under the New Zealand Threatened Classification system for plants, with the qualifier "Sp" (Sparse).
