Myosotis explanata is a species of flowering plant in the family Boraginaceae, endemic to high-elevation habitats in the South Island of New Zealand. Thomas Cheeseman described the species in 1906. Plants of this species of forget-me-not are perennial rosettes with ebracteate inflorescences and white corollas with stamens that are partly exserted, with the tips of the anthers only surpassing the scales.

Myosotis is a genus of flowering plants in the family Boraginaceae. The name comes from the Ancient Greek μυοσωτίς "mouse's ear", which the foliage is thought to resemble. In the Northern Hemisphere, they are colloquially known as forget-me-nots or scorpion grasses. Myosotis alpestris is the official flower of Alaska and Dalsland, Sweden. Plants of the genus are not to be confused with Chatham Islands' forget-me-nots, which belong to the related genus Myosotidium.
