The Guernsey Centaury (Exaculum pusillum) is a species of plant in the Gentianaceae family.
This species is very rare in Britain, confined to, as it's name suggests, Guernsey. Similar to other gentians and centauries, this species has light pink flowers on small and slender erect stems. The flowers are similar to other gentian flowers, in being held quite erect, with the petals folding at the edge. This species flowers from July till September, and is found coastal grasslands.
