Hi Rowan, it may or may not have a tag name I have long since given up even trying to keep track of the myriad postulates being promulgated for orchids. The salient point is that the genus Corybas - and yes I use Corybas - needs a serious multidisciplinary revision combing cytogenetic, DNA based molecular methodologies and morpological data. This is happening in part in Australia and in part in New Zealand - but a full revision is needed and until it is much confusion will remain.
