See text The Oncidiinae is a subtribe within the Orchidaceae that consists of a number of genera that are closely related.

This subtribe consists of about 70 genera with over 1000 species, with Oncidium as its largest genus.

These genera consist of a single floral type based on the angle of the attachment of the lip to the column, reflecting pollinator preferences.

These were transferred to Gomesa and a new genus Nohawilliamsia, has been described for Oncidium orthostates[1] Most species have well-developed pseudobulbs and conduplicate leaves.
