'''Shetland Mouse-ear''' ''Cerastium nigrescens'', also known as '''Shetland Mouse-eared Chickweed''' or '''Edmondston's Chickweed''', is an [[endemism|endemic]] [[plant]] found in [[Shetland]], [[Great Britain]].

It was first recorded in 1837 by Shetland [[botanist]] [[Thomas Edmondston]], who was 12 at the time. For a long time it was [[synonomised]] with Arctic Mouse-ear ''[[Cerastium arcticum]]'' but it is now widely regarded as a separate species. Although reported from two other sites in the 19th century, it currently grows only on two [[serpentine]] hills on the island of [[Unst]].
