Thank you Tony and Jenny Dominelli for confirming the id of this species for us

General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
We were very excited to find this little single stemmed plant under mallee trees, amounst the leaf/bark litter.
The whole plant is only 160mm tall, with the fruit cluster only 15mm high.
We missed this flowering last year, but now we just caught it in April ... last flower remaining.
In our area the only other midge orchid it could be is Red Midge-orchid (Genoplesium rufum).
In relation to the "sheath" photo, Robert Lawrence said "This genus only has one leaf and that is tightly wrapped around the scape. What you have in this picture is the sheath that protects the new shoot until it emerges from the ground."
