Plants of this species of forget-me-not are perennial rosettes with ebracteate inflorescences and white corollas with exserted stamens.

[2][4] It was raised to species rank by Heidi Meudt, Jessica Prebble, Rebecca Stanley, and Michael Thorsen in 2013.

pottsiana was collected by Anthony Druce in 1956, and the holotype is lodged at the Allan Herbarium of Manaaki Whenua - Landcare Research (CHR 87624).

[7] In addition, several individuals of Myosotis pottsiana were included in two different studies that phylogenetically analysed amplified fragment length polymorphisms (AFLPs) of the informal M. petiolata species group.

Both surfaces of the leaf are uniformly and densely covered in straight, appressed, antrorse (forward-facing) hairs.

Each rosette has multiple ascending, branched ebracteate (or sometimes partially bracteate) inflorescences that are up to 430 mm long.

[8] Although once thought to be extinct,[6] Myosotis pottsiana is known from a handful of populations in Bay of Plenty, North Island, New Zealand from 40 to 300 m ASL, on vertical rock walls, steep river banks and forest bluffs.
