This orchid was first formally described in 2006 by David Jones and Mark Clements from a specimen collected from Cockies Creek State Forest and which later flowered in the Australian National Botanic Gardens. It was given the name Tropilis eungellensis and the description was published in Australian Orchid Research.[3] In 2014, Julian Shaw changed the name to Dendrobium eungellensis.[4] The specific epithet (eungellensis) refers to the main distribution of the species - the ending -ensis is a Latin suffix meaning "of" or "in".[5]
