Brassavola is a genus of 21 orchids. They were named in 1813 by the Scottish botanist Robert Brown. The name comes from the Italian nobleman and physician Antonio Musa Brassavola. This genus is abbreviated B. in trade journals.
Cattleya is a genus of orchids from Costa Rica south to Argentina. The genus is abbreviated C in trade journals.
Laelia is a small genus of 25 species in the orchid family (Orchidaceae). Laelia species are found in areas of subtropical or temperate climate in Central and South America, but mostly in Mexico. Laelia is abbreviated L. in the horticultural trade.
× Brassolaeliocattleya, abbreviated Blc. in the horticultural trade, is the orchid nothogenus for intergeneric hybrid greges containing at least one ancestor species from each of the three ancestral genera BrassavolaR.Br., CattleyaLindl. and Laelia Lindl., and from no other genera.
× Epicattleya is an intergeneric orchid hybrid. The nothogenus is abbreviated Epc. in the horticultural trade.
× Epilaeliocattleya, abbreviated Eplc. in the horticultural trade, is the nothogenus consisting of all intergeneric orchid hybrids descended from at least one species in each of the parent genera, and from no other natural genera.
× Hawkinsara, abbreviated Hknsa. in the horticultural trade, is an intergeneric hybrid of orchids, with parent genera Broughtonia, Cattleya, Laelia and Sophronitis.
× Laeliocatonia is a nothogenus of intergeneric orchid hybrids descended from the parent genera Laelia, Cattleya and Broughtonia. It is abbreviated Lctna. in the horticultural trade.
× Potinara, abbreviated Pot in the horticultural trade, is the nothogenus comprising those intergeneric hybrids of orchids which have Brassavola, Cattleya, Laelia and Sophronitis as parent genera.
× Schombocattleya is a historic intergeneric hybrid of orchids since all species of Schomburgkia have been transferred to either Laelia or Myrmecophila. The genus was abbreviated Smbc. in the horticultural trade. Plants of the World Online treats it as a synonym of × Laeliocattleya.
× Sophrolaeliocattleya is a nothogenus of artificial intergeneric orchid hybrids. It is abbreviated as Slc. in the horticultural trade. As of 2008, × Sophrolaeliocattleya is defunct, with the genus Sophronitis having been merged into Cattleya.
× Howeara, abbreviated as Hwra. in the horticultural trade, is the nothogenus for intergeneric hybrid of the three genera Leochilus, Oncidium and Rodriguezia.
Cattleya purpurata, known in the past as Laelia purpurata and Sophronitis purpurata, is native to Brazil where it is very popular among orchid growers. It is an epiphyte that is found in the canopy of tall trees near coastal areas, in the Brazilian states of Rio Grande do Sul, Santa Catarina and São Paulo. The orchid favors bright light and cool to warm conditions and is relative easy to cultive. C. purpurata has been used extensively as a parent in hybridizing with Cattleyas. Cattleya purpurata blooms from late spring to fall with three to five flowers on a spike. The flowers are long-lasting and fragrant.
× Aliceara, abbreviated Alcra. in the horticultural trade, is the nothogenus for intergeneric hybrids between three orchid genera.
× Bratonia, abbreviated Brat. in the horticultural trade, is the nothogenus for intergeneric hybrids between the orchid genera Brassia and Miltonia. An incorrect synonym for this nothogenus is × Miltassia (Mtssa.).
The term grex, derived from the Latin noun grex, gregis, meaning 'flock', has been expanded in 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, and individual orchid plants can be selected and named as cultivars.
× Cattlianthe, abbreviated Ctt. in the horticultural trade, is the orchid nothogenus for intergeneric hybrid greges containing at least one ancestor species from each of the two ancestral genera Cattleya and Guarianthe, and from no other genera.
× Laeliocatarthron, abbreviated Lcr. in the horticultural trade, is the nothogenus containing intergeneric hybrids with at least one ancestor in each of the natural genera Cattleya, Caularthron, and Laelia, and with no ancestors in any other natural genera.
Papilionanthe is a genus of flowering plants from the orchid family, Orchidaceae. It is native to Southeast Asia, southern China, and the Indian Subcontinent.
× Rhyncholaeliocattleya, abbreviated Rlc. in the horticultural trade, is the orchid nothogenus for intergeneric hybrid greges containing at least one ancestor species from each of the two ancestral genera RhyncholaeliaSchltr. and CattleyaLindl., and from no other genera.
