'''''Myosotis suavis''''' is a species of [[flowering plant]] in the [[Family (taxonomy)|family]] [[Boraginaceae]], [[Endemism|endemic]] to the [[South Island]] of [[New Zealand]]. [[Donald Petrie (botanist)|Donald Petrie]] described the species in 1914. Plants of this species of [[Forget-me-nots|forget-me-not]] are [[Perennial plant|perennial]] rosettes with ebracteate inflorescences and white corollas with stamens that are partially exserted.
''M. suavis'' is distributed among rocky alpine habitats in the South Island in the [[Canterbury Region|Canterbury]], [[Westland, New Zealand|Westland]], and [[Otago]] regions. It is listed as data deficient by the [[New Zealand Threat Classification System]].
== Description == '''''Myosotis suavis''''' plants are rosettes. The rosette leaves have long [[Petiole (botany)|petioles]] that are shorter than the leaf blades. The rosette leaf blades are 20–40 mm long by 7–15 mm wide, broadly obovate-spathulate, widest at or above the middle, with an [[Obtuse (leaf)|obtuse]] apex. The upper surface of the leaf is uniformly and densely covered in appressed antrorse (forward-facing) hairs, whereas the lower surface is uniformly and sparsely covered in appressed retrorse (backward-facing) hairs.
Each rosette has few ascending, ebracteate [[inflorescence]]s that are up to 100 mm long. The cauline leaves are similar to the rosette leaves, but are smaller, become smaller toward the top of the inflorescence, narrow-elliptic, and sessile, and have hairs similar to the rosette leaves. The flowers are several per inflorescence, and each is borne on a short [[Pedicel (botany)|pedicel]], without a bract. The calyx is 5–8 mm long at flowering and fruiting, lobed to more than one-half of its length, and with densely distributed, appressed to erect hairs, some of which are retrorse near the base and others hooked. The corolla is white and 5–7 mm in diameter, with a cylindrical tube, and small scales alternating with the petals. The anthers are partially exserted, with the tips only surpassing the faucal scales. The nutlets were not described.<ref name=":2">{{Cite web |last=Moore |first=L.B. |title=Boraginaceae.
