We continue to use the genus names per Sanders. There have been many changes in taxonomy accepted by the RHS and AOS, including the elimination of the Sophronitis genus, plants in these genera are now known as Brassocattleya (Bc.), Cahuzacara (Chz.), Cattleya (C.), Cattlianthe (Ctt.), Rhyncattleanthe (Rth.) and Rhyncholaeliocattleya (Rlc.). In the hope of avoiding confusion, we also show the new genus names in parentheses where different from Sanders nomenclature.
