"Dendrobium deleonii is most similar to Den. sanderae var. major Hort., but differs in the proportionately shorter sidelobes, the shorter and proportionately wider midlobe. The mid lobe of Den. sanderae var. major is angled downwards at the junction of the sidelobes and midlobe whereas the midlobe of Den. deleonii is straight or slightly curved. When similar-sized flowers are viewed ventrally, the throat of Den. deleonii is narrower. The leaves of Den. deleonii are also proportionately smaller and less curved than those of Den. sanderae var. major.." Cabactulan, M.D. De Leon, Cootes, and Pimentel 2019
