× Colmanara, abbreviated Colm. in the horticultural trade,[1] is the nothogenus comprising intergeneric hybrids between the orchid genera Miltonia, Odontoglossum and Oncidium (Milt. × Odm. × Onc.).
The name refers to Jeremiah Colman (1859–1942), an English collector of orchids,[2] and uses the suffix -ara used to form nothogenera of orchids. The nothogenus was established in 1936.[3]
In the current botanical classifications according to Genera Orchidacearum by Alec M. Pridgeon, Phillip J. Cribb, Mark W. Chase, and Finn N. Rasmussen, Odontoglossum is merged into Oncidium and × Colmanara is considered to be the same as the nothogenus × Miltonidium. The RHS Orchid register does not register × Colmanara anymore.
