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.
Eulophia, commonly known as corduroy orchids, is a genus of about two hundred species of flowering plants in the orchid family, Orchidaceae. Most Eulophia orchids are terrestrial but some are deciduous while others are evergreen. They either have an underground rhizome or pseudobulbs on the surface and those species with leaves have them on the end of a fleshy stem. The flowers are arranged on a thin flowering spike, the flowers having sepals which are larger than the petals. The genus is widely distributed but most species are found in Africa and Asia, usually growing in shady places with grass or shrubs in forests.
Epidendroideae is a subfamily of plants in the orchid family, Orchidaceae. Epidendroideae is larger than all the other orchid subfamilies together, comprising more than 15,000 species in 576 genera. Most epidendroid orchids are tropical epiphytes, typically with pseudobulbs. There are, however, some terrestrials such as Epipactis and even a few myco-heterotrophs, which are parasitic upon mycorrhizal fungi.

Aerangidinae is classified as a subtribe within the tribe Vandeae in the family Orchidaceae. However, it is likely to soon become a synonym of Angraecinae with the genera below re-allocated to this sub-tribe. As traditionally circumscribed, it consists of 36 genera and about 300 species. The type genus of this subtribe is Aerangis. Members of this group are epiphytic orchids having a monopodial habit and are endemic to tropical Africa and Madagascar. They are distinguished from the other subtribes in Vandeae by having an elongate rostellum, an elongate spur, and two pollinia. Most genera in the group indicate pollination by moths, however leaf beetles are reported as frequent visitors, but it is unknown whether they are vectors for pollination.
Rhipidoglossum is a genus of flowering plants from the orchid family, Orchidaceae. It contains about 20-30 species, all from sub-Saharan Africa.
