epipetric plant

An epipetric plant is a plant that grows on rocks for physical support, rather than in the ground. These plants, also known as lithophytes, are not parasitic and do not draw nutrients from their rock substrate. They are commonly found in moist, shaded environments, such as forests, where they can access sunlight and collect organic debris for nutrients.12

Epipetric plants obtain water from rain and atmospheric moisture. Some species have specialized leaves to absorb water, while others use their roots. Many epipetric plants, particularly ferns, have adaptations for dry conditions, such as thick cuticles and hairy surfaces. Some cacti also grow as epiphytes on rocks, often with thin stems to absorb water and reduced spines.13
