Brassolaeliocattleya, abbreviated Blc. in the horticultural trade, is the orchid nothogenus for intergeneric hybrid greges

Grex (horticulture)

The term grex , derived from the Latin noun grex, gregis meaning flock, has been coined to expand botanical nomenclature to describe horticultural hybrids of orchids, based solely on their specified parentage...

Cattleya

Cattleya is a genus of 113 species of orchids from Costa Rica to tropical South America. The genus was named in 1824 by John Lindley after Sir William Cattley who received and successfully cultivated specimens of Cattleya labiata that were used as packing material in a shipment of other orchids...

Laelia

Laelia, abbreviated L. in the horticultural trade, is a small genus of 25 species from the orchid family . This is one of the most important and popular orchid genera, because of the beautiful flowers, their genetic properties and because they are fairly easy in culture. It is probably named after...

 Lindl., and from no other genera.

Nomenclatural history

As the name was used in 1999, there were many greges which were among the most spectacular of cultivated orchids, being particularly valued for the large showy labellum

Labellum

Labellum is the Latin diminutive of labium, meaning lip. These are anatomical terms used descriptively in biology, for example in Entomology and botany.-Botany:...

. By 2009, the "Brassavola" parents most commonly used in producing Brassolaeliocattleyas had been moved into the genus Rhyncholaelia

Rhyncholaelia

Rhyncholaelia, abbreviated Rl. in the horticultural trade, is a genus of orchids , comprising 2 species. They are distributed in Mexico, Guatemala, Belize, and Honduras. Both species were originally published in Brassavola by Lindley. In 1918, Schlechter erected the new genus Rhyncholaelia and...

, and the "Laelia" parents most commonly used in producing Brassolaeliocattleyas had been moved into the genus Cattleya. As a result, most of the greges that were classified as Brassolaeliocattleyas in 1999 are now classified in the nothogenus Rhyncholaeliocattleya

Rhyncholaeliocattleya

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 Rhyncholaelia Schltr. andCattleya Lindl., and from no other genera.The many greges in this...
