CAM metabolism, a water-preserving metabolism present among various plant taxa, is particularly relevant to epiphytic communities.[1] For example, it is estimated that among epiphytic orchids, as many as 50% are likely to use it.[2] Other relevant epiphytic families which display such metabolism are Bromeliacee (e.g. in genera Aechmea and Tillandsia), Cactaceae (e.g. in Rhipsalis and Epiphyllum) and Apocynaceae (e.g. in Hoya and Dischidia).[citation needed]
