About

Myosotidium is a genus of plants belonging to the family Boraginaceae. This genus is represented by the single species Myosotidium hortensia, the Chatham Islands lily, giant forget-me-not or Chatham Islands forget-me-not, which is endemic to the Chatham Islands, New Zealand. In the Māori language, it is known by the name kopukapuka.

The biogeography is yet unresolved, but its ancestors may have originated from the American continent, as Myosotidium hortensia was found to be sister to the South American plant genus Selkirkia and both genera being sister to the North American genus Mimophytum.
