Question: Which horticultural trade is commonly known as Angrek, Angraecum or Ascocenda?

full_context: Document 1: Epiphyllum hybrid: The plants known as epiphyllum hybrids, epiphyllums, epicacti or just epis, widely grown for their flowers, are artificial hybrids of species within the group of cacti placed in the tribe Hylocereeae, particularly species of "Disocactus", "Pseudorhipsalis" and "Selenicereus". In spite of the common name, species in the genus "Epiphyllum" are less often involved as parents of epiphyllum hybrids.
Document 2: Ascocenda: × Ascocenda, abbreviated as Ascda in the horticultural trade, is a man-made hybrid orchid genus resulting from a cross between "Ascocentrum" and "Vanda" (Asctm × V). It was first described in Orchid Rev. 57: 172 (1949).
Document 3: Degarmoara: × Degarmoara, abbreviated Dgmra. in the horticultural trade, is the nothogenus comprising intergeneric hybrids between the orchid genera "Brassia", "Miltonia" and "Odontoglossum" (Brs. x Milt. x Odm.).
Document 4: Buddleja × whiteana: Buddleja × whiteana is a hybrid of "Buddleja alternifolia" and "Buddleja asiatica" made at the Blandy Experimental Farm, Boyce, VA, USA, in 1948 by R.J.Moore. The plant was named for Orlando E. White, Director of Botany at Blandy. However, the taxonomy of the plant is a matter of contention, the RBG Kew "Plantlist" treating the status of its name as 'unresolved'. 
Document 5: Catasetum: Catasetum, abbreviated as Ctsm in horticultural trade, is a genus of showy epiphytic Orchids, family Orchidaceae, subfamily Epidendroideae, tribe Cymbidieae, subtribe Catasetinae, with 166 species, many of which are highly prized in horticulture.
Document 6: Catawbiense hybrid: A catawbiense hybrid is a hybrid of the plant genus "Rhododendron", derived from crosses of American species "Rhododendron catawbiense" and "Rhododendron maximum" with European and Asian species "R. arboreum", "R. caucaseum" and "R. ponticum".
Document 7: Grex (horticulture): The term grex (pl. greges or grexes; abbreviation gx), derived from the Latin noun "grex, gregis" meaning 'flock', has been coined to expand botanical nomenclature to describe hybrids of orchids, based solely on their parentage. Grex names are one of the three categories of plant names governed by the International Code of Nomenclature for Cultivated Plants; within a grex the "cultivar group" category can be used to refer to plants by their shared characteristics (rather than by their parentage), and individual orchid plants can be selected (and propagated) and named as cultivars.
Document 8: Brassocattleya: Brassocattleya or Brasso-cattleya, abbreviated Bc. in the horticultural trade, is an intergeneric orchid hybrid derived from the genera "Brassavola" and "Cattleya".
Document 9: Coryanthes: Coryanthes, commonly known as bucket orchids, is a genus of tropical epiphytic orchids. This genus is abbreviated as Crths in horticultural trade. They are native to South America, Central America, Mexico and Trinidad.
Document 10: Phalaenopsis: Phalaenopsis , known as moth orchids, abbreviated Phal in the horticultural trade, is an orchid genus of approximately 60 species. "Phalaenopsis" is one of the most popular orchids in the trade, through the development of many artificial hybrids. It is native to southern China, Taiwan, the Indian Subcontinent, Southeast Asia (Thailand, Philippines, Malaysia, Indonesia, etc.), New Guinea, the Bismarck Archipelago, and Queensland.
Document 11: Acanthaceae: Acanthaceae is a family (the acanthus family) of dicotyledonous flowering plants containing almost 250 genera and about 2500 species. Most are tropical herbs, shrubs, or twining vines; some are epiphytes. Only a few species are distributed in temperate regions. The four main centres of distribution are Indonesia and Malaysia, Africa, Brazil, and Central America. The representatives of the family can be found in nearly every habitat, including dense or open forests, scrublands, wet fields and valleys, sea coast and marine areas, swamps, and mangrove forests.
Document 12: Aerangis: Aerangis, abbreviated as Aergs in horticultural trade, is a genus of the Orchid family (Orchidaceae). The name of this genus has been derived from the Greek words 'aer' (air) and 'angos' (urn), referring to the form of the lip. It is the type genus of the subtribe Aerangidinae. Approximately 50 species in this genus are known mostly from tropical Africa, but also from the Comoro Islands, Madagascar and Sri Lanka.
Document 13: Hybrid orangutan: A hybrid orangutan or cocktail orangutan is a usually captive-born orangutan derived from interbreeding between Bornean ("Pongo pygmaeus") and Sumatran ("Pongo abelii") orangutans. The topic of orangutan speciation was poorly understood until the 1980s, when genetics revealed that orangutans actually comprise these two genetically distinct species. Before this was known, orangutans from differing species were paired in captivity, and in some cases produced hybrid offspring. Subsequently, the government of Indonesia and the organization that oversees zoo programs in the United States suggested to stop interbreeding of Sumatran and Bornean orangutans and called for disallowing hybrids to reproduce.
Document 14: Bulbophyllum: Bulbophyllum is the largest genus in the orchid family Orchidaceae. With more than 2,000 species, it is also one of the largest genera of flowering plants, exceeded only by "Astragalus". This genus is abbreviated in the trade journals as Bulb. It is found throughout most of the warmer parts of the world: Africa, southern Asia, Latin America, the West Indies, and various islands in the Indian and Pacific Oceans.
Document 15: Angraecum: The genus Angraecum, abbreviated as Angcm in horticultural trade, common name Angrek (Indonesian and Malay) or Comet Orchid, contains about 220 species.
ground_truth: Angraecum
