Epiphyte plants growing above ground that do not feed from their tree support (for example through their haustorium or feeding part having dug into the tree, such as Mistletoe) have subaerial roots (for example some Ficus species).
Epiphytic plants that grow above the ground and do not obtain nutrients directly from their host trees (like Mistletoe using a haustorium to penetrate or feeding parts digging into the tree) possess aerial roots. Some examples include certain Ficus species.
