Photographed near
Portland on 14 June 2011.
Separated out as a distinct species by
Bob Bates, this orchid usually grows with other shell orchids but no
hybrids have been noted. Its type location is Nora Creina Bay, SA
but Bates also notes it's located in the Portland area, which is why after
an unsuccessful attempt to find it in SA we also looked into Portland on
the way home. Reading Bob's description and looking at the
accompanying photo I feel we have found it!
It can be
distinguished from other shell orchids by its tri-colour flower, with a
gap between the lateral sepals and galea. The lateral sepals are
fine and arch forwards. As it is in the Diplodium family the flower
does not have a rosette, but the non-flowering plants have a large
crenulate leaf rosette.
