Dendrobium is a genus of mostly epiphytic and lithophytic orchids in the family Orchidaceae. It is a very large genus, containing more than 1,800 species that are found in diverse habitats throughout much of south, east and southeast Asia, including China, Japan, India, the Philippines, Indonesia, Australia, New Guinea, Vietnam and many of the islands of the Pacific. Orchids in this genus have roots that creep over the surface of trees or rocks, rarely having their roots in soil. Up to six leaves develop in a tuft at the tip of a shoot and from one to a large number of flowers are arranged along an unbranched flowering stem. Several attempts have been made to separate Dendrobium into smaller genera, but most have not been accepted by the World Checklist of Selected Plant Families.

It is popular in Australian native horticulture and is a commonly cultivated orchid among Australian orchid species growers.
Dendrobium antennatum, commonly known as the green antelope orchid, is an epiphytic orchid in the family Orchidaceae.

It occurs in tropical North Queensland, Australia and New Guinea.
Dendrobium discolor, commonly known as antler orchid or golden orchid, is a species of epiphytic or lithophytic orchid in the family Orchidaceae, and are native to northern Australia, New Guinea, and part of Indonesia. It has cylindrical pseudobulbs, each with between ten and thirty five leathery leaves, and flowering stems with up to forty mostly brownish or greenish flowers with wavy and twisted sepals and petals.
Dendrobium jonesii, commonly known as the oak orchid is a species of epiphytic or lithophytic orchid endemic to far north Queensland.

Dendrobium tetragonum, commonly known as the tree spider orchid, is a variable species of epiphytic or lithophytic orchid endemic to eastern Australia. Tree spider orchids are unusual in having pendulous pseudobulbs that are thin and wiry near the base then expand into a fleshy, four-sided upper section before tapering at the tip. There are only a few thin but leathery leaves at the end of the pseudobulbs and up to five flowers on relatively short flowering stems. To allow for the variations in the species there are five subspecies and a variety, some with a unique common name.
Dendrobium smillieae, commonly known as the bottlebrush orchid, is an epiphytic or lithophytic orchid with large, spongy pseudobulbs, thin, bright green leaves which are shed after their first year and crowded flowers in a bottlebrush-like arrangement. The flowers are white, to cream-coloured or pink and the labellum has a shiny, dark green tip. This orchid species is found in some of the Torres Strait Islands, and through Cape York Peninsula to Townsville, Queensland. It is also found in New Guinea and eastern Indonesia.
Dendrobium johannis, commonly known as the chocolate tea tree orchid, is a species of epiphytic or lithophytic orchid native to Australia and New Guinea. It has spindle-shaped pseudobulbs, between five and ten dark green leaves with purplish markings and flowering stems with up to fifteen chocolate brown flowers with a yellow labellum.

It has cane-like pseudobulbs which grow up to 2 metres long and 2–3 centimetres (0.8–1.2 in) in diameter. Its inflorescences are up to 75 cm (30 in) long with many flowers, up to 5 cm (2.0 in) across. Its leaves are oblong or lanceolate, and up to 15 cm (6 in) long. They last two to three months and bloom throughout the year in the native habitat.

It grows in tropical North Queensland and New Guinea.
Dendrobium carronii, commonly known as the pink tea tree orchid, is a small epiphytic orchid in the family Orchidaceae.

Dendrobium schuetzei, sometimes called Schuetze's dendrobium, is a species of orchid endemic to northeastern Mindanao, Philippines. Though widely grown as an ornamental, it is classified as Critically Endangered by the IUCN Red List of Threatened Species due to habitat loss and unsustainable harvesting from the wild.
