Definition: Cryptocreagris is a genus of plants in the family Asteraceae, commonly known as mosses and lichens. They are characterized by their small size, typically less than 2-3 cm tall, and their lack of leaves or stems, making them ideal for growing on rocks, cliffs, and other rocky surfaces. Cryptocreagris is often associated with the rock formations found in the Mediterranean region, where they can thrive as a natural part of the ecosystem.
