Dendrobium enigmaticum Ormerod strongly resembles D. taurinum Lindl. and D. nindii W. Hill in the shape of the lip . It differs from D. taurinum in having 3 apically elevated keels on the lip (versus 1) and the flower colour with shades of yellow and brown (versus white to pale green with purple). D. nindii has 3 apically decurrent keels (versus apically elevated keels) and flowers white to pale green with purple.
Based on 2 additional collections cultivated at the firm Sanders in England, one of which collected in 1898 by W. Micholitz in "German New Guinea", Ormerod suggests that Dendrobium enigmaticum may have originally been collected somewhere in what is now Papua New Guinea.
