Dendrobium of the orchidacea family from the subtropical and tropical regions of Asia, Australia and New Zealand. There are 1220 species in various biotopes. The name consists of Greek words δένδον (Dendron) = tree and βίος (bios) = life (literally living on trees because all species are epiphytic, more rarely lithophytes). After Bulbophyllum, Dendrobium represents the second most important genus of orchids in number of species. The genus is characterized by the stem consisting of pseudobulbs.
