infima Meudt & Heenan is a subspecies of flowering plant in the family Boraginaceae, endemic to central South Island of New Zealand.

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

[1] The holotype was collected by Peter Heenan and Miles Giller in Canterbury, Waipara, South Dean and is lodged at the Allan Herbarium of Manaaki Whenua - Landcare Research (CHR 666639).

[1][4] The subspecific epithet, infima, means lowest or lowermost in Latin (infimus),[5] and refers to the filaments in the flower which are attached much lower in the corolla tube than those of M. goyenii subsp.

infima found on limestone and calcareous siltstone in Marlborough and Canterbury and M. goyenii subsp.

infima form 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).

infima plants are single rosettes with fibrous roots that often grow together to form caespitose clumps or tufts.

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.
