Cochlearia pyrenaica Pyrenean Scurveygrass RR DD N
This plant is found on spoil heaps and damp grassland on basic soils on Northern England and Southern Scotland. It looks like the other Cochlearia officinalis (Common Scurvygrass) at first glance but examination of the fruits should show them to be rounder and the leaves are generally smaller than the other common plants of the Cochlearia genus.
This plant is likely to be ssp pyrenaica which has its stronghold in the Teesdale area of northern England.
