Wilsonara

×Wilsonara, abbreviated as Wils. in the horticultural trade, is the nothogenus for intergeneric hybrids between the three orchid genera "Cochlioda", "Odontoglossum" and "Oncidium" (Cda. x Odm. x Onc.).
In the current botanical classifications according to Genera Orchidacearum by Alec M. Pridgeon, Phillip J. Cribb, Mark W. Chase, and Finn N. Rasmussen, Odontoglossum and Cochlioda are almost completely merged into Oncidium and most of the x Wilsonara are considered to be interspecific crosses whithin Oncidium or some might be called x Cochlicidium for the Cochlioda x Oncidium hybrids.
