For. eg. Cattleya Lembera it has been registered with unknown parentage in 1919 by someone named C.J. Philips. It is parent of Rhyncholaeliocattleya Dorothy Drury-Lowe. Rlc. Dorothy Drury-Lowe is a parent of 2 offspring Rlc. Brocade and Rlc. Jane Helton. These two plants are parents of 108 hybrids which are some of the main Rlc. hybrids in the business and parents of countless other hybrids. So I think if a plant is extremely wonderful in some criteria, people will be willing to accept it without a pedigree LOL.
