"Although the name Dockrillia was established as far back as 1981, it is only in recent years that the name has been resurrected. The genus Dockrillia has been split off from Dendrobium and comprises the "terete-leaved" group of "dendrobes". This revision has been generally accepted in Australia. Species in Dockrillia are characterised by succulent leaves which are rounded in cross-section (terete) and which arise from a creeping rhizome. Currently about 28 species are recognised. Dockrillia is named after Alick Dockrill."
