Epiphytic orchids are orchids that grow non-parasitically on trees, and derive their moisture and nutrients from the air and dampness (rain and cloud moisture) on the surface of the hosts. Epiphytic orchids are the main group of tropical orchids. They attach to their hosts high in the canopy to gain more light for photosynthesis. Roots are developed primarily for support. The roots also have a modified aerial root called velamen. The velamen is a thick layer of dead cells which cover the roots of epiphytic orchids. It is silvery gray or white in color when dry and usually more green when wet. It is capable of absorbing atmospheric moisture and nutrients.
Epiphytic orchids have roots that are often grown to hold tight to the surface of pots or potting material, exposed to the elements. They grow well in potting with a very open and free-draining material that is not soil. Pieces of brick, charcoal, fern root, wooden baskets, logs, tree stumps, or coconut fiber are good material to plant epiphytic orchids, as these material retain moisture but allow aeration, and they are long lasting. Epiphytic orchids are never half-buried under potting mixture, rather they sit right on top of it.
There is only one species, known as Abdominea minimiflora, also known as Tiny-flowered Abdominea.
Abdominea minimiflora is a monopodial epiphytic orchid in the family Orchidaceae. It is the sole species in the genus Abdominea, and is also known as Tiny-flowered Abdominea. The name Abdominea is derived from the Latin abdomen, meaning belly. It refers to the similarity with the shape of an abdomen and the labellum (lip) of an insect. This species of orchid is found in Thailand, Malaysia, Java and the Philippines. It bears an inflorescence of many small flowers, which is 0.45 cm across.

Laelia is a small genus of epiphytic orchids in the family Orchidaceae, comprising about 11 species. It is native to subtropical and temperate regions of Central America, mostly in Mexico. Laelia is abbreviated as L in horticultural trade.
Most Laelia species are epiphytes but some are lithophytes, such as Laelia anceps. Laelia species are closely related to Cattleya, only differing in the number of pollinia. Their stems are short, with ovate pseudobulbs, 6-30 cm long. Each pseudobulb produces one or two waxy, leathery leaves. Each leave can grow up to 20 cm long. The inflorescence is a raceme of 30 cm long, with up to eight flowers, growing from the apex of the the pseudobulb. The color of the orchid flowers is ranged from pink to purple with a darker shade lip which becoming white close to the column. The albino variety is a highly sought after and prized variety.
Laelia species are easy to cultivate, and some are highly drought-tolerant.
