Note: Dendrobium congianum Averyanov 2016 differs from Dendrobium wattii "in much smaller flowers and relatively long median lip lobe. It may be close to Dendrobium vocongii Schettler et D.M. Pham (Schettler and Minh, 2016) closely allied to Dendrobium wattii, from which differs in smaller, almost pure white flowers and entire acute (not emarginate) epichile. It is highly probable that Dendrobium vocongii is natural hybrid, which exhibits visible intermediate vegetative and floral morphology between Dendrobium wattii and our new species and obviously originated by means their natural hybridization."
