A hemiepiphyte is a plant that spends part of its life cycle as an epiphyte. The seeds of primary hemiepiphytes germinate in the canopy and initially live epiphytically. They send roots downward, and these roots eventually make contact with the ground. Secondary epiphytes begin as rooted vines growing upward from the forest floor, but later break their connection to the ground.[1]

Strangler figs are hemiepiphytic – they may begin life as epiphytes but after making contact with the ground they encircle their host tree and "strangle" it. This usually results in the death of the host tree, either through girdling or through competition for light.[2] Strangler figs can also germinate and develop as independent trees, not reliant on the support of a host.
