Confused

Q I recently purchased a plant listed as Rossioglossum williamsianum. It now appears that this plant is really Ross.Rawdon Jester. What are the parents of this hybrid and is it really a Rossioglossum or an intergeneric hybrid?

A  Rossiogkossum is the new name for this group, formerly known as odontoglossums and still treated as such by the Royal Horticultural Society for registration purposes. Rossioglossum Rawdon Jester (grande x williamsianum) is listed by the RHS as Odontoglossum Rawdon Jester. NedNash.
