NEcology #91 - Calcareous Cliffs and Their Carnivorous Colonizers

Plant carnivory? Check! Inaccessible habitat? Check! Weird geology? Check! Pinguicula vulgaris the "Common Butterwort" has a pretty widespread distribution across the globe, but the special sauce it needs to truly thrive is at a premium in New England. A dweller of sun-scorched, basic cliff faces, it eludes the vast majority of casual observers, despite being well worth the effort to see!
