Greyish Forget-me-not (Myosotis traversii var. cinerascens)
The Greyish Forget-me-not, a subspecies of Traver’s Forget-me-not (Myosotis traversii Hook. f.), was restricted to exposed limestone cliff faces in the semi-alpine Castle Hill Basin in Canterbury, South Island, New Zealand.
The plant is known only from a handful of specimens collected in the 18th and 19th century, it was not found since and is thought to be possiblky extinct.
