• Type: "N.S.W., at Burrawang; collected by A.W. Dockrill, Nov., 1946. (TYPES lodged in the National Herbaria of Sydney and Melbourne.)"

• Etymology: "The character of the labellum, in particular, is surely unique; it is bent at an almost perfect right angle at the middle, and the anterior half is rigidly extended like a tail between the paired sepals. The name has been given in allusion to this feature and was suggest by Mr. J. H. Willis of the Victorian National Herbarium."
