× Wilsonara, abbreviated as Wils. in the horticultural trade, was a nothogenus of orchids, set up for plants produced by crosses between the three genera Cochlioda, Odontoglossum and Oncidium. , Cochlioda and Odontoglossum were treated as synonyms of Oncidium, so that plants correctly treated formerly as × Wilsonara fall within Oncidium.
