"Morphologically Bulbophyllum konstantinovii Aver. 2013 may be closest to Bulbophyllum simplicilabellum Seidenf. andB. didymotropis Seidenf. described from Thailand, but distinctly differs in 3 nerved sepals, broadly ovate, oblique, acute petals, broad cup-like, cordate broadening of column foot apex and inflated fleshy margin of the lip."
