Myosotis oreophila plants are rosettes. The rosette leaves have long
petioles that are about as long the leaf blades and difficult to distinguish from them. The rosette leaves are up to 40 mm long by 10 mm wide, linear-spathulate, widest at or above the middle, with an
obtuse,
apiculate apex. The upper surface of the leaf is uniformly and densely covered in appressed antrorse (forward-facing) hairs mixed with retrorse (backward-facing) hairs, whereas the lower surface is uniformly and sparsely covered in appressed and mostly retrorse hairs. Each rosette has few ascending to erect, ebracteate
inflorescences that are up to 70 mm long. The cauline leaves are similar to the rosette leaves, but are smaller, become smaller toward the top of the inflorescence, linear-oblong, and subacute. The flowers are several per inflorescence, and each is borne on a short
pedicel, without a bract. The calyx is 6–9 mm long at flowering and fruiting, lobed to less than one-half of its length, and with many hairs, some of which are retrorse near the base and others hooked. The corolla is white, with a cylindrical tube, and small scales alternating with the petals. The anthers are partially exserted. The nutlets are 1.8–2.4 × 1.0–1.2 mm. The
