Osyris is a genus of plants in the family Santalaceae, one of the many genera known as sandalwoods.
The species of this genus are mostly hemiparasitic, meaning although they can survive and grow by themselves, they also opportunistically tap into the root systems of nearby plants and parasitize them.
