×Wilsonara
× Wilsonara is a former hybrid genus of orchids made by crossing Cochlioda, Odontoglossum and Oncidium; those genera are now merged into Oncidium, so these plants are grown and sold as Oncidium-type orchids. Care follows the typical Oncidium-type hybrid: bright light, airy mix and careful watering.
× 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. As of April 2026, Cochlioda and Odontoglossum were treated as synonyms of Oncidium, so that plants correctly treated formerly as × Wilsonara fall within Oncidium.
