Yamadaara was a combination of Cattleya, Brassavola, Laelia and Encyclia. It is no longer in official use. So many species in these genera have been reclassified as something else that many old names for hybrid genera were scrapped and new ones created.
This plant is now a Maumeneara, the only one of its kind, combining Cattleya, Guarianthe, Brassavola, Rhyncholaelia, Laelia, and Encyclia. Other former Yamadaara are under other names now depending on what species ended up in what genera.
