Lithophytes are plants that grow in or on rocks. Epilithic (or epipetric) lithophytes grow on the surfaces of rocks, while endolithic (or chasmophytes) lithophytes grow in the cracks or crevices of rocks. Obligate lithophytes grow solely on rocks, while facultative lithophytes will grow partially on a rock and on another substrate simultaneously.
