Braya longii

Braya longii, common name Long's Braya or Long's northern rockcress, is a small, herbaceous, arctic-alpine flowering plant that grows only in the cool, wet and windy climate of the coastal limestone barrens of northern Newfoundland. It is a narrow endemic, found in only five populations within a range of 6 km, and in one isolated population 14 km to the south, all in the Strait of Belle Isle ecoregion on the extreme northwest portion of the Great Northern Peninsula of Newfoundland.
