Bulbophyllum is a genus of mostly epiphytic and lithophytic orchids in the family Orchidaceae. It is the largest genus in the orchid family and one of the largest genera of flowering plants with more than 2,000 species, exceeded in number only by Astragalus. These orchids are found in diverse habitats throughout most of the warmer parts of the world including Africa, southern Asia, Latin America, the West Indies, and various islands in the Indian and Pacific Oceans. Orchids in this genus have thread-like or fibrous roots that creep over the surface of trees or rocks or hang from branches. The stem is divided into a rhizome and a pseudobulb, a feature that distinguished this genus from Dendrobium. There is usually only a single leaf at the top of the pseudobulb and from one to many flowers are arranged along an unbranched flowering stem that arises from the base of the pseudobulb. Several attempts have been made to separate Bulbophyllum into smaller genera, but most have not been accepted by the World Checklist of Selected Plant Families.
Dinema is a genus of orchids. It is represented by a single currently accepted species, Dinema polybulbon, native to Mexico, Central America, and the Caribbean.
Bulbophyllum fletcherianum, the tongue orchid, Fletcher's bulbophyllum or Spies' bulbophyllum, is a rare orchid native to southern New Guinea.

It grows on shrubs, trees and rocks, often in exposed situations.
Bulbophyllum longiflorum, commonly known as the pale umbrella orchid, is a species of epiphytic or lithophytic orchid. It has a creeping rhizome, widely spaced, dark green pseudobulbs with a single large, fleshy leaf, and flowers spreading in a semicircular umbel, resembling one-half of an umbrella. The flowers are canoe-shaped, greenish cream-coloured to yellowish with purple dots. It has a wide distribution and is found in parts of Africa, on islands in the Indian and Pacific Oceans, Southeast Asia, New Guinea and northern Australia.

It has tiny, crowded, slightly flattened, dark green pseudobulbs, a single thick, fleshy leaf and a single dark red to purplish red flower with a narrow labellum. It grows on trees and rocks in sheltered places.
Bulbophyllum rosemarianum is a species of orchid in the genus Bulbophyllum.
Bulbophyllum shepherdii, commonly known as the wheat-leaf rope orchid, is a species of epiphytic or lithophytic orchid that forms a dense mat of branching rhizomes pressed against the surface on which it grows. The pseudobulbs are well spaced along the rhizome, each with a single egg-shaped leaf and a single small, white or cream-coloured flower with yellow tips. It grows on trees and rocks in rainforest and is endemic to eastern Australia.
Bulbophyllum sphaericum is a species of orchid in the genus Bulbophyllum. It is found in Sichuan and Yunnan, providence of China. The Bulbophyllum sphaericum is a warm to cool growing epiphyte with a creeping, branching rhizome with .4" [1 cm] between each globose pseudobulb carrying a single, apical, thickly leathery, elliptic-oblong, abaxially purplish red, adaxially pale green, margin slightly recurved, retuse apically, sessile base leaf that blooms in the summer on an erect, basal from the pseudobulb, much longer than the leaf, 4 to 5 flowered inflorescence holding the flowers in an apical umbel.
Bulbophyllum wolfei, commonly known as the fleshy snake orchid, is a species of epiphytic or lithophytic orchid with thin, creeping rhizomes, and flattened pseudobulbs each with a single thick, fleshy, dark green leaf and a single cream-coloured flower with dark red stripes.
