The falsa sanicola (Petagnaea gussonei) is an endangered herbaceous plant endemic to North-East Sicily in the Nebrodi mountains. It typically grows on the borders of shaded woodland streams at an altitude of 204-1,500 metres above sea level. The leaves are made up of 5 equal lobes with small teeth that serrate the edges. It blooms white flowers throughout May and June and can grow up to 45cm in height. It is largely distinguished by its strong celery aroma. There are only a few populations remaining, scattered over an area of approximately 400m². It is believed that increased water usage in the area will draw away from the plant's habitat, resulting in a decline of habitat quality and number of individuals.
